If the resulting layout is smaller horizontally than the area it needs to fill, the extra space is distributed to each column in proportion to its weight. A column that has a weight of zero receives no extra space.

If all the weights are zero, all the extra space appears between the grids of the cell and the left and right edges.

The default value of this field is 0. weightx should be a non-negative value.

 
See Also:
GridBagConstraints.clone() , GridBagConstraints.weighty

weighty

Reads default serializable fields from the stream. Reads from the stream a string and an array of bytes as additional data.

Serial Data:
The String is the name of one of CS_* constants defined in the ColorSpace class if the profile object is a profile for a predefined color space (for example "CS_sRGB"). The string is null otherwise.

The byte[] array is the profile data for the profile. It will usually be null for the predefined profiles.

If the string is recognized as a constant name for predefined color space the object will be resolved into profile obtained with getInstance(int cspace) and the profile data are ignored. Otherwise the object will be resolved into profile obtained with getInstance(byte[] data).

Serial Data:
The String is the name of one of CS_* constants defined in the ColorSpace class if the profile object is a profile for a predefined color space (for example "CS_sRGB"). The string is null otherwise.

The byte[] array is the profile data for the profile. For predefined color spaces null is written instead of the profile data. If in the future versions of Java API new predefined color spaces will be added, future versions of this class may choose to write for new predefined color spaces not only the color space name, but the profile data as well so that older versions could still deserialize the object.

Serialization Overview

Class Class is special cased within the Serialization Stream Protocol. A Class instance is written intially into an ObjectOutputStream in the following format:
      TC_CLASS ClassDescriptor
      A ClassDescriptor is a special cased serialization of 
      a java.io.ObjectStreamClass instance. 
 
A new handle is generated for the initial time the class descriptor is written into the stream. Future references to the class descriptor are written as references to the initial class descriptor instance.

Serialization Methods

readObject


private void readObject ( ObjectInputStream in)
 throws IOException,
 ClassNotFoundException
readObject for custom serialization.

This method reads this object's serialized form for this class as follows:

The readObject method is invoked on in to read this object's unique identifier (a UID instance).

Next, the readUTF method is invoked on in to read the external ref type name of the RemoteRef instance for this object's activator. Next, the RemoteRef instance is created of an implementation-specific class corresponding to the external ref type name (returned by readUTF), and the readExternal method is invoked on that RemoteRef instance to read the external form corresponding to the external ref type name.

Note: If the external ref type name is "UnicastRef", "UnicastServerRef", "UnicastRef2", "UnicastServerRef2", or "ActivatableRef", a corresponding implementation-specific class must be found, and its readExternal method must read the serial data for that external ref type name as specified to be written in the serialData documentation for this class. If the external ref type name is any other string (of non-zero length), a ClassNotFoundException will be thrown, unless the implementation provides an implementation-specific class corresponding to that external ref type name, in which case the RemoteRef will be an instance of that implementation-specific class.

Throws:
IOException
ClassNotFoundException

writeObject


private void writeObject ( ObjectOutputStream out)
 throws IOException,
 ClassNotFoundException
writeObject for custom serialization.

This method writes this object's serialized form for this class as follows:

The writeObject method is invoked on out passing this object's unique identifier (a UID instance) as the argument.

Next, the getRefClass method is invoked on the activator's RemoteRef instance to obtain its external ref type name. Next, the writeUTF method is invoked on out with the value returned by getRefClass, and then the writeExternal method is invoked on the RemoteRef instance passing out as the argument.

Serial Data:
The serialized data for this class comprises a java.rmi.server.UID (written with ObjectOutput.writeObject) followed by the external ref type name of the activator's RemoteRef instance (a string written with ObjectOutput.writeUTF), followed by the external form of the RemoteRef instance as written by its writeExternal method.

The external ref type name of the RemoteRef instance is determined using the definitions of external ref type names specified in the RemoteObject writeObject method serialData specification. Similarly, the data written by the writeExternal method and read by the readExternal method of RemoteRef implementation classes corresponding to each of the defined external ref type names is specified in the RemoteObject writeObject method serialData specification.

Serialization Methods

readObject


private void readObject ( ObjectInputStream in)
 throws IOException,
 ClassNotFoundException
readObject for custom serialization.

This method reads this object's serialized form for this class as follows:

The readUTF method is invoked on in to read the external ref type name for the RemoteRef instance to be filled in to this object's ref field. If the string returned by readUTF has length zero, the readObject method is invoked on in, and than the value returned by readObject is cast to RemoteRef and this object's ref field is set to that value. Otherwise, this object's ref field is set to a RemoteRef instance that is created of an implementation-specific class corresponding to the external ref type name returned by readUTF, and then the readExternal method is invoked on this object's ref field.

If the external ref type name is "UnicastRef", "UnicastServerRef", "UnicastRef2", "UnicastServerRef2", or "ActivatableRef", a corresponding implementation-specific class must be found, and its readExternal method must read the serial data for that external ref type name as specified to be written in the serialData documentation for this class. If the external ref type name is any other string (of non-zero length), a ClassNotFoundException will be thrown, unless the implementation provides an implementation-specific class corresponding to that external ref type name, in which case this object's ref field will be set to an instance of that implementation-specific class.

Throws:
IOException
ClassNotFoundException

writeObject


private void writeObject ( ObjectOutputStream out)
 throws IOException,
 ClassNotFoundException
writeObject for custom serialization.

This method writes this object's serialized form for this class as follows:

The getRefClass method is invoked on this object's ref field to obtain its external ref type name. If the value returned by getRefClass was a non-null string of length greater than zero, the writeUTF method is invoked on out with the value returned by getRefClass, and then the writeExternal method is invoked on this object's ref field passing out as the argument; otherwise, the writeUTF method is invoked on out with a zero-length string (""), and then the writeObject method is invoked on out passing this object's ref field as the argument.

Serial Data:
The serialized data for this class comprises a string (written with ObjectOutput.writeUTF) that is either the external ref type name of the contained RemoteRef instance (the ref field) or a zero-length string, followed by either the external form of the ref field as written by its writeExternal method if the string was of non-zero length, or the serialized form of the ref field as written by passing it to the serialization stream's writeObject if the string was of zero length.

If this object is an instance of RemoteStub or RemoteObjectInvocationHandler that was returned from any of the UnicastRemoteObject.exportObject methods and custom socket factories are not used, the external ref type name is "UnicastRef". If this object is an instance of RemoteStub or RemoteObjectInvocationHandler that was returned from any of the UnicastRemoteObject.exportObject methods and custom socket factories are used, the external ref type name is "UnicastRef2". If this object is an instance of RemoteStub or RemoteObjectInvocationHandler that was returned from any of the java.rmi.activation.Activatable.exportObject methods, the external ref type name is "ActivatableRef". If this object is an instance of RemoteStub or RemoteObjectInvocationHandler that was returned from the RemoteObject.toStub method (and the argument passed to toStub was not itself a RemoteStub), the external ref type name is a function of how the remote object passed to toStub was exported, as described above. If this object is an instance of RemoteStub or RemoteObjectInvocationHandler that was originally created via deserialization, the external ref type name is the same as that which was read when this object was deserialized.

If this object is an instance of java.rmi.server.UnicastRemoteObject that does not use custom socket factories, the external ref type name is "UnicastServerRef". If this object is an instance of UnicastRemoteObject that does use custom socket factories, the external ref type name is "UnicastServerRef2".

Following is the data that must be written by the writeExternal method and read by the readExternal method of RemoteRef implementation classes that correspond to the each of the defined external ref type names:

For "UnicastRef":

  • the hostname of the referenced remote object, written by DataOutput.writeUTF(String)
  • the port of the referenced remote object, written by DataOutput.writeInt(int)
  • the data written as a result of calling {link java.rmi.server.ObjID#write(java.io.ObjectOutput)} on the ObjID instance contained in the reference
  • the boolean value false, written by DataOutput.writeBoolean(boolean)

For "UnicastRef2" with a null client socket factory:

  • the byte value 0x00 (indicating null client socket factory), written by DataOutput.writeByte(int)
  • the hostname of the referenced remote object, written by DataOutput.writeUTF(String)
  • the port of the referenced remote object, written by DataOutput.writeInt(int)
  • the data written as a result of calling {link java.rmi.server.ObjID#write(java.io.ObjectOutput)} on the ObjID instance contained in the reference
  • the boolean value false, written by DataOutput.writeBoolean(boolean)

For "UnicastRef2" with a non-null client socket factory:

  • the byte value 0x01 (indicating non-null client socket factory), written by DataOutput.writeByte(int)
  • the hostname of the referenced remote object, written by DataOutput.writeUTF(String)
  • the port of the referenced remote object, written by DataOutput.writeInt(int)
  • a client socket factory (object of type java.rmi.server.RMIClientSocketFactory), written by passing it to an invocation of writeObject on the stream instance
  • the data written as a result of calling {link java.rmi.server.ObjID#write(java.io.ObjectOutput)} on the ObjID instance contained in the reference
  • the boolean value false, written by DataOutput.writeBoolean(boolean)

For "ActivatableRef" with a null nested remote reference:

  • an instance of java.rmi.activation.ActivationID, written by passing it to an invocation of writeObject on the stream instance
  • a zero-length string (""), written by DataOutput.writeUTF(String)

For "ActivatableRef" with a non-null nested remote reference:

  • an instance of java.rmi.activation.ActivationID, written by passing it to an invocation of writeObject on the stream instance
  • the external ref type name of the nested remote reference, which must be "UnicastRef2", written by DataOutput.writeUTF(String)
  • the external form of the nested remote reference, written by invoking its writeExternal method with the stream instance (see the description of the external form for "UnicastRef2" above)

For "UnicastServerRef" and "UnicastServerRef2", no data is written by the writeExternal method or read by the readExternal method.

Class java.text.DecimalFormat extends NumberFormat

serialVersionUID:  864413376551465018L

Serialization Methods

readObject


private void readObject ( ObjectInputStream stream)
 throws IOException,
 ClassNotFoundException
Reads the default serializable fields from the stream and performs validations and adjustments for older serialized versions. The validations and adjustments are:
  1. Verify that the superclass's digit count fields correctly reflect the limits imposed on formatting numbers other than BigInteger and BigDecimal objects. These limits are stored in the superclass for serialization compatibility with older versions, while the limits for BigInteger and BigDecimal objects are kept in this class. If, in the superclass, the minimum or maximum integer digit count is larger than DOUBLE_INTEGER_DIGITS or if the minimum or maximum fraction digit count is larger than DOUBLE_FRACTION_DIGITS, then the stream data is invalid and this method throws an InvalidObjectException.
  2. If serialVersionOnStream is less than 3, then call the setters for the minimum and maximum integer and fraction digits with the values of the corresponding superclass getters to initialize the fields in this class. The fields in this class are new with version 3.
  3. If serialVersionOnStream is less than 1, indicating that the stream was written by JDK 1.1, initialize useExponentialNotation to false, since it was not present in JDK 1.1.
  4. Set serialVersionOnStream to the maximum allowed value so that default serialization will work properly if this object is streamed out again.

Stream versions older than 2 will not have the affix pattern variables posPrefixPattern etc. As a result, they will be initialized to null, which means the affix strings will be taken as literal values. This is exactly what we want, since that corresponds to the pre-version-2 behavior.

Serialization Methods

readObject


private void readObject ( ObjectInputStream stream)
 throws IOException,
 ClassNotFoundException
Reconstitutes this object from a stream (i.e., deserialize it).

Throws:
IOException
ClassNotFoundException

writeObject


private void writeObject ( ObjectOutputStream stream)
 throws IOException
Save the state of this object to a stream (i.e., serialize it). Ideally, Calendar would only write out its state data and the current time, and not write any field data out, such as fields[], isTimeSet, areFieldsSet, and isSet[]. nextStamp also should not be part of the persistent state. Unfortunately, this didn't happen before JDK 1.1 shipped. To be compatible with JDK 1.1, we will always have to write out the field values and state flags. However, nextStamp can be removed from the serialization stream; this will probably happen in the near future.

Throws:
IOException
Serialized Fields

fields


int[] fields 
The calendar field values for the currently set time for this calendar. This is an array of FIELD_COUNT integers, with index values ERA through DST_OFFSET.

 

isSet


boolean[] isSet 
The flags which tell if a specified calendar field for the calendar is set. A new object has no fields set. After the first call to a method which generates the fields, they all remain set after that. This is an array of FIELD_COUNT booleans, with index values ERA through DST_OFFSET.

 

time


long time 
The currently set time for this calendar, expressed in milliseconds after January 1, 1970, 0:00:00 GMT.

 
See Also:
Calendar.isTimeSet

isTimeSet


boolean isTimeSet 
True if then the value of time is valid. The time is made invalid by a change to an item of field[].

 
See Also:
Calendar.time

areFieldsSet


boolean areFieldsSet 
True if fields[] are in sync with the currently set time. If false, then the next attempt to get the value of a field will force a recomputation of all fields from the current value of time.

 

lenient


boolean lenient 
True if this calendar allows out-of-range field values during computation of time from fields[].

 
See Also:
Calendar.setLenient(boolean) , Calendar.isLenient()

zone

 TimeZonezone 
The TimeZone used by this calendar. Calendar uses the time zone data to translate between locale and GMT time.

 

firstDayOfWeek


int firstDayOfWeek 
The first day of the week, with possible values SUNDAY, MONDAY, etc. This is a locale-dependent value.

 

minimalDaysInFirstWeek


int minimalDaysInFirstWeek 
The number of days required for the first week in a month or year, with possible values from 1 to 7. This is a locale-dependent value.

 

nextStamp


int nextStamp 
The next available value for stamp[], an internal array. This actually should not be written out to the stream, and will probably be removed from the stream in the near future. In the meantime, a value of MINIMUM_USER_STAMP should be used.

 

serialVersionOnStream


int serialVersionOnStream 
The version of the serialized data on the stream. Possible values:
0 or not present on stream
JDK 1.1.5 or earlier.
1
JDK 1.1.6 or later. Writes a correct 'time' value as well as compatible values for other fields. This is a transitional format.
When streaming out this class, the most recent format and the highest allowable serialVersionOnStream is written.

The contents of the byte array are the true values of the fields startDay, startDayOfWeek, endDay, and endDayOfWeek. The values of these fields in the required section are approximate values suited to the rule mode DOW_IN_MONTH_MODE, which is the only mode recognized by JDK 1.1.

IOException
Serialized Fields

startMonth


int startMonth 
The month in which daylight saving time starts. This value must be between Calendar.JANUARY and Calendar.DECEMBER inclusive. This value must not equal endMonth.

If useDaylight is false, this value is ignored.

 

startDay


int startDay 
This field has two possible interpretations:
startMode == DOW_IN_MONTH
startDay indicates the day of the month of startMonth on which daylight saving time starts, from 1 to 28, 30, or 31, depending on the startMonth.
startMode != DOW_IN_MONTH
startDay indicates which startDayOfWeek in th month startMonth daylight saving time starts on. For example, a value of +1 and a startDayOfWeek of Calendar.SUNDAY indicates the first Sunday of startMonth. Likewise, +2 would indicate the second Sunday, and -1 the last Sunday. A value of 0 is illegal.

If useDaylight is false, this value is ignored.

 

startDayOfWeek


int startDayOfWeek 
The day of the week on which daylight saving time starts. This value must be between Calendar.SUNDAY and Calendar.SATURDAY inclusive.

If useDaylight is false or startMode == DAY_OF_MONTH, this value is ignored.

 

startTime


int startTime 
The time in milliseconds after midnight at which daylight saving time starts. This value is expressed as wall time, standard time, or UTC time, depending on the setting of startTimeMode.

If useDaylight is false, this value is ignored.

 

startTimeMode


int startTimeMode 
The format of startTime, either WALL_TIME, STANDARD_TIME, or UTC_TIME.

 
Since:
1.3

endMonth


int endMonth 
The month in which daylight saving time ends. This value must be between Calendar.JANUARY and Calendar.UNDECIMBER. This value must not equal startMonth.

If useDaylight is false, this value is ignored.

 

endDay


int endDay 
This field has two possible interpretations:
endMode == DOW_IN_MONTH
endDay indicates the day of the month of endMonth on which daylight saving time ends, from 1 to 28, 30, or 31, depending on the endMonth.
endMode != DOW_IN_MONTH
endDay indicates which endDayOfWeek in th month endMonth daylight saving time ends on. For example, a value of +1 and a endDayOfWeek of Calendar.SUNDAY indicates the first Sunday of endMonth. Likewise, +2 would indicate the second Sunday, and -1 the last Sunday. A value of 0 is illegal.

If useDaylight is false, this value is ignored.

 

endDayOfWeek


int endDayOfWeek 
The day of the week on which daylight saving time ends. This value must be between Calendar.SUNDAY and Calendar.SATURDAY inclusive.

If useDaylight is false or endMode == DAY_OF_MONTH, this value is ignored.

 

endTime


int endTime 
The time in milliseconds after midnight at which daylight saving time ends. This value is expressed as wall time, standard time, or UTC time, depending on the setting of endTimeMode.

If useDaylight is false, this value is ignored.

 

endTimeMode


int endTimeMode 
The format of endTime, either WALL_TIME, STANDARD_TIME, or UTC_TIME.

 
Since:
1.3

startYear


int startYear 
The year in which daylight saving time is first observed. This is an AD value. If this value is less than 1 then d
