Method Detail

• prepareDecoding

  void prepareDecoding(int onDiskSizeWithoutHeader,
                     int uncompressedSizeWithoutHeader,
                     ByteBuffer blockBufferWithoutHeader,
                     ByteBuffer onDiskBlock)
                       throws IOException

  Perform all actions that need to be done before the encoder's real decoding process. Decompression needs to be done if HFileContext.getCompression() returns a valid compression algorithm.

  Parameters:

  onDiskSizeWithoutHeader - numBytes after block and encoding headers

  uncompressedSizeWithoutHeader - numBytes without header required to store the block after decompressing (not decoding)

  blockBufferWithoutHeader - ByteBuffer pointed after the header but before the data

  onDiskBlock - on disk data to be decoded

  Throws:

  IOException

• getHFileContext

  HFileContext getHFileContext()

  Returns:

  HFile meta information
