Method Detail

setColumnCount

public void setColumnCount(int columnCount)
                    throws java.sql.SQLException

Description copied from class: RowSetMetaDataImpl

Sets to the given number the number of columns in the RowSet object for which this RowSetMetaDataImpl object was created.

Specified by:

setColumnCount in interface javax.sql.RowSetMetaData

Overrides:

setColumnCount in class RowSetMetaDataImpl

Parameters:

columnCount - an int giving the number of columns in the RowSet object

Throws:

java.sql.SQLException - if the given number is equal to or less than zero

setColumnClassName

public void setColumnClassName(int columnIndex,
                               java.lang.String className)
                        throws java.sql.SQLException

Specified by:

setColumnClassName in interface RowSetMetaDataX

Throws:

java.sql.SQLException

setDefinitelyWritable

public void setDefinitelyWritable(int columnIndex,
                                  boolean value)
                           throws java.sql.SQLException

Specified by:

setDefinitelyWritable in interface RowSetMetaDataX

Throws:

java.sql.SQLException

setReadOnly

public void setReadOnly(int columnIndex,
                        boolean value)
                 throws java.sql.SQLException

Specified by:

setReadOnly in interface RowSetMetaDataX

Throws:

java.sql.SQLException

setWritable

public void setWritable(int columnIndex,
                        boolean value)
                 throws java.sql.SQLException

Specified by:

setWritable in interface RowSetMetaDataX

Throws:

java.sql.SQLException

getColumnClassName

public java.lang.String getColumnClassName(int columnIndex)
                                    throws java.sql.SQLException

Description copied from class: RowSetMetaDataImpl

Retrieves the fully-qualified name of the class in the Java programming language to which a value in the designated column will be mapped. For example, if the value is an int, the class name returned by this method will be java.lang.Integer.

If the value in the designated column has a custom mapping, this method returns the name of the class that implements SQLData. When the method ResultSet.getObject is called to retrieve a value from the designated column, it will create an instance of this class or one of its subclasses.

Specified by:

getColumnClassName in interface java.sql.ResultSetMetaData

Overrides:

getColumnClassName in class RowSetMetaDataImpl

Parameters:

columnIndex - the first column is 1, the second is 2, and so on; must be between 1 and the number of columns, inclusive

Returns:

the fully-qualified name of the class in the Java programming language that would be used by the method RowSet.getObject to retrieve the value in the specified column. This is the class name used for custom mapping when there is a custom mapping.

Throws:

java.sql.SQLException - if a database access error occurs or the given column number is out of bounds

isDefinitelyWritable

public boolean isDefinitelyWritable(int columnIndex)
                             throws java.sql.SQLException

Description copied from class: RowSetMetaDataImpl

Indicates whether a write operation on the designated column will definitely succeed.

Specified by:

isDefinitelyWritable in interface java.sql.ResultSetMetaData

Overrides:

isDefinitelyWritable in class RowSetMetaDataImpl

Parameters:

columnIndex - the first column is 1, the second is 2, and so on; must be between 1 and the number of columns, inclusive

Returns:

true if a write operation on the designated column will definitely succeed; false otherwise

Throws:

java.sql.SQLException - if a database access error occurs or the given column number is out of bounds

isReadOnly

public boolean isReadOnly(int columnIndex)
                   throws java.sql.SQLException

Description copied from class: RowSetMetaDataImpl

Indicates whether the designated column is definitely not writable, thus readonly.

Specified by:

isReadOnly in interface java.sql.ResultSetMetaData

Overrides:

isReadOnly in class RowSetMetaDataImpl

Parameters:

columnIndex - the first column is 1, the second is 2, and so on; must be between 1 and the number of columns, inclusive

Returns:

true if this RowSet object is read-Only and thus not updatable; false otherwise

Throws:

java.sql.SQLException - if a database access error occurs or the given column number is out of bounds

isWritable

public boolean isWritable(int columnIndex)
                   throws java.sql.SQLException

Description copied from class: RowSetMetaDataImpl

Indicates whether it is possible for a write operation on the designated column to succeed. A return value of true means that a write operation may or may not succeed.

Specified by:

isWritable in interface java.sql.ResultSetMetaData

Overrides:

isWritable in class RowSetMetaDataImpl

Parameters:

columnIndex - the first column is 1, the second is 2, and so on; must be between 1 and the number of columns, inclusive

Returns:

true if a write operation on the designated column may will succeed; false otherwise

Throws:

java.sql.SQLException - if a database access error occurs or the given column number is out of bounds
