Constructor Detail

TypedValue

protected TypedValue()

Protected default constructor.

TypedValue

public TypedValue(java.lang.Object value)

Constructor with value Object. Use only if value is not null.

Parameters:

value -

TypedValue

public TypedValue(FieldType type,
                  java.lang.Object value)

Constructor with FieldType and value Object. Use if value may be null.

Method Detail

typeOfValue

public static FieldType typeOfValue(java.lang.Object value)

Returns the field type corresponding to value Object's class.

Parameters:

value -

getStringValue

public java.lang.String getStringValue()

Returns a string representation of the underlying value object.

getType

public FieldType getType()

Returns the field type.

getValue

public java.lang.Object getValue()

Returns the value Object, which will be one of: Integer, BigDecimal, Long, or String.

Returns:

The typed value object or null.

getComparableValue

protected java.lang.Comparable getComparableValue()

Returns the value Object, which is also Comparable. It will be one of: Integer, BigDecimal, Long, or String. If this TypedValue instance is the result of deserialization, this lazily-creates the value object.

Returns:

The typed value object or null.

Throws:

java.lang.IllegalStateException - If the type has been changed to differ than the value's inherant type. This theoretically can only happen via reflection and/or a bad serialization state.

setValue

public void setValue(java.lang.Object object)

Sets the type, string value (for serialization/persistence), and the transient value object itself.

Parameters:

object - The new value object.

Throws:

java.lang.IllegalArgumentException - If the object cannot be used.

convertToTypedValue

public static java.lang.Object convertToTypedValue(java.lang.String value,
                                                   FieldType type)

Parses the given string based on the FieldType

Parameters:

value - String to parse

type - FieldType to convert the string

Returns:

Object returned from the conversion

toString

public java.lang.String toString()

Returns the toString() result of the underlying value object.

Overrides:

toString in class java.lang.Object

compareTo

public int compareTo(TypedValue o)

Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

Specified by:

compareTo in interface java.lang.Comparable<TypedValue>

Parameters:

o - the object to be compared.

Returns:

a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

Throws:

java.lang.ClassCastException - if the specified object's type prevents it from being compared to this object.

equals

public boolean equals(java.lang.Object object)

Indicates whether some other object is "equal to" this one.

Overrides:

equals in class java.lang.Object

Parameters:

object - the reference object with which to compare.

Returns:

true if this object is the same as the obj argument; false otherwise.

See Also:

hashCode(), Hashtable

hashCode

public int hashCode()

Returns a hash code value for the object. This method is supported for the benefit of hashtables such as those provided by java.util.Hashtable.

Overrides:

hashCode in class java.lang.Object

Returns:

a hash code value for this object.

Object.equals(java.lang.Object), Hashtable
