public static final byte[] zeroLengthBytes

zeroLengthBinary

public static final BinaryData zeroLengthBinary

Constructor Detail

BinaryData

public BinaryData(byte[] data,
                  boolean clone)

This constructor is used inside the engine when an already serialized byte[] is read from a file (.log, .script, .data or text table source). In this case clone is false. When a byte[] is submitted as a parameter of PreparedStatement then clone is true.
