Method Detail

• open

  public void open(DataSpec dataSpec)
            throws IOException

  Description copied from interface: DataSink
  Opens the sink to consume the specified data.

  Note: If an IOException is thrown, callers must still call DataSink.close() to ensure that any partial effects of the invocation are cleaned up.

  Specified by:

  open in interface DataSink

  Parameters:

  dataSpec - Defines the data to be consumed.

  Throws:

  IOException - If an error occurs opening the sink.

• close

  public void close()
             throws IOException

  Description copied from interface: DataSink
  Closes the sink.

  Note: This method must be called even if the corresponding call to DataSink.open(DataSpec) threw an IOException. See DataSink.open(DataSpec) for more details.

  Specified by:

  close in interface DataSink

  Throws:

  IOException - If an error occurs closing the sink.

• write

  public void write(byte[] buffer,
                    int offset,
                    int length)
             throws IOException

  Description copied from interface: DataSink
  Consumes the provided data.

  Specified by:

  write in interface DataSink

  Parameters:

  buffer - The buffer from which data should be consumed.

  offset - The offset of the data to consume in buffer.

  length - The length of the data to consume, in bytes.

  Throws:

  IOException - If an error occurs writing to the sink.

• getData

  public byte[] getData()

  Returns the data written to the sink since the last call to open(DataSpec), or null if open(DataSpec) has never been called.
