Constructor Detail

DefaultColumnValue

public DefaultColumnValue(java.lang.String columnName,
                          oracle.sql.Datum columnData,
                          int columnDataType)
                   throws StreamsException

Constructs a DefaultColumnValue object with columnName, columnData, and columnDataType.
When columnData is NULL, a valid columnDataType is expected. When columnData is not NULL, the columnDataType is ignored. The mapping is maintained internally.

Parameters:

columnName - The column name, cannot be NULL

columnData - The column data.

columnDataType - The column data type.

Throws:

StreamsException - is thrown if the columnName is NULL, or the columnData is NULL and the columnDataType is invalid

DefaultColumnValue

public DefaultColumnValue(java.lang.String columnName,
                          oracle.sql.Datum columnData)
                   throws StreamsException

Constructs a DefaultColumnValue object with columnName and columnData.
This constructor can be used when columnData is not null. The mapping between columnData and columnDataType is maintained internally.

Parameters:

columnName - the column name, cannot be NULL.

columnData - the column data, cannot be NULL.

Throws:

StreamsException - is thrown if the columnData is NULL and the columnDataType is invalid.

Method Detail

getColumnName

public java.lang.String getColumnName()

Gets the column name.

Specified by:

getColumnName in interface ColumnValue

Returns:

A string contains the column name.

setColumnName

public void setColumnName(java.lang.String columnName)

Sets the column name.

Specified by:

setColumnName in interface ColumnValue

Parameters:

columnName - The column name.

getColumnData

public oracle.sql.Datum getColumnData()

Gets the column data.
Column data can be an instance of one of the following oracle.sql.Datum subclasses:
oracle.sql.CHAR
oracle.sql.RAW
oracle.sql.DATE
oracle.sql.NUMBER
oracle.sql.BINARY_FLOAT
oracle.sql.BINARY_DOUBLE
oracle.sql.TIMESTAMP
oracle.sql.TIMESTAMPTZ
oracle.sql.TIMESTAMPLTZ
oracle.sql.INTERVALYM
oracle.sql.INTERVALDS

Specified by:

getColumnData in interface ColumnValue

Returns:

A oracle.sql.Datum object that contains the column data.

setColumnData

public void setColumnData(oracle.sql.Datum columnData,
                          int columnDataType)
                   throws StreamsException

Sets the column data.
When columnData is NULL, columnDataType must be a valid non-NULL value. When columnData is non-NULL, the columnDataType is ignored. The mapping is maintained internally.

Specified by:

setColumnData in interface ColumnValue

Parameters:

columnData - the column data, instance of oracle.sql.Datum subclasses.

columnDataType - the column data type as defined in ColumnValue.

Throws:

StreamsException - is thrown if the columnData is NULL and the columnDataType is invalid.

getColumnDataType

public int getColumnDataType()

Gets the column data type as defined in ColumnValue interface.

Specified by:

getColumnDataType in interface ColumnValue

Returns:

an integer that indicates the column data type.

getTDEFlag

public boolean getTDEFlag()

Gets the Transparent Data Encryption (TDE) flag. This flag indicates whether TDE was enabled for this column.

Specified by:

getTDEFlag in interface ColumnValue

Returns:

A boolean value indicates whether TDE was enabled.

setTDEFlag

public void setTDEFlag(boolean tdeFlag)

Sets the TDE flag. This method is used to set the TDE flag for the column. When this flag is set, the column data is encrypted if the LCR is spilled or put into an error queue.

Specified by:

setTDEFlag in interface ColumnValue

Parameters:

tdeFlag - A boolean value indicates whether TDE Flag should be set.

is32kData

public boolean is32kData()

Indicates whether the column is an extended size column (maximum size of 32767 bytes).

Specified by:

is32kData in interface ColumnValue

set32kData

public void set32kData(boolean is32kData)

Sets the extended size column flag (maximum size of 32767 bytes).
This flag indicates whether the column is an extended size column.

Specified by:

set32kData in interface ColumnValue

Parameters:

is32kData - The extended size column flag.

setCharsetId

public void setCharsetId(int charsetId)

Sets the Oracle character set ID for the column.
Some types of columns, such as XMLTYPE columns, contain character data stored in raw byte format (oracle.sql.RAW). The character set ID is required to interpret the character data properly.

Specified by:

setCharsetId in interface ColumnValue

Parameters:

charsetId - The character set ID.

See Also:

CharacterSet

getCharsetId

public int getCharsetId()

Gets the column character set identifier (ID).
Some types of columns, such as XMLTYPE columns, contain character data stored in raw byte format (oracle.sql.RAW). The character set ID is required to interpret the character data properly.

Specified by:

getCharsetId in interface ColumnValue

Returns:

An interger that identifies the character set.

CharacterSet

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
