Constructor Detail

ByteArrayRow

public ByteArrayRow(byte[][] internalRowData,
                    ExceptionInterceptor exceptionInterceptor,
                    ValueDecoder valueDecoder)

ByteArrayRow

public ByteArrayRow(byte[][] internalRowData,
                    ExceptionInterceptor exceptionInterceptor)

Method Detail

isBinaryEncoded

public boolean isBinaryEncoded()

getBytes

public byte[] getBytes(int index)

Description copied from interface: Row

Returns the value at the given column as a byte array. The bytes represent the raw values returned by the server.

Parameters:

index - index of column (starting at 0) to return from.

Returns:

the value for the given column; if the value is SQL NULL, the value returned is null

setBytes

public void setBytes(int index,
                     byte[] value)

Description copied from interface: Row

Sets the given byte array as a raw column value (only works currently with ByteArrayRow).

Parameters:

index - index of the column (starting at 0) to set to.

value - the (raw) value to set

getNull

public boolean getNull(int columnIndex)

Description copied from interface: Row

Check whether a column is NULL and update the 'wasNull' status.

Parameters:

columnIndex - of the column value (starting at 0) to check.

Returns:

true if the column value is NULL, false if not.

getValue

public <T> T getValue(int columnIndex,
                      ValueFactory<T> vf)

Implementation of getValue() based on the underlying byte array. Delegate to superclass for decoding.

Type Parameters:

T - type to decode to

Parameters:

columnIndex - index of column to retrieve value from (0-indexed, not JDBC 1-indexed)

vf - value factory used to create the return value after decoding

Returns:

The return value from the value factory
