Method Detail

• isFirst

  boolean isFirst()

• readKey

  void readKey(ByteBuffer in,
             int keyLength,
             int valueLength)

  Analyze the key and fill the state. Uses mark() and reset() in ByteBuffer.

  Parameters:

  in - Buffer at the position where key starts

  keyLength - Length of key in bytes

  valueLength - Length of values in bytes

• readKey

  void readKey(ByteBuffer in,
             int keyLength,
             int valueLength,
             int commonPrefix,
             CompressionState previousState)

  Analyze the key and fill the state assuming we know previous state. Uses mark() and reset() in ByteBuffer to avoid moving the position.

  This method overrides all the fields of this instance, except prevOffset, which is usually manipulated directly by encoders and decoders.

  Parameters:

  in - Buffer at the position where key starts

  keyLength - Length of key in bytes

  valueLength - Length of values in bytes

  commonPrefix - how many first bytes are common with previous KeyValue

  previousState - State from previous KeyValue

• readTimestamp

  protected void readTimestamp(ByteBuffer in)

• copyFrom

  void copyFrom(CompressionState state)
