示例1: readBuffer

import org.apache.hadoop.io.compress.CompressionInputStream; //導入方法依賴的package包/類
/** Read a compressed buffer */
private synchronized void readBuffer(DataInputBuffer buffer, 
                                     CompressionInputStream filter) throws IOException {
  // Read data into a temporary buffer
  DataOutputBuffer dataBuffer = new DataOutputBuffer();

  try {
    int dataBufferLength = WritableUtils.readVInt(in);
    dataBuffer.write(in, dataBufferLength);
  
    // Set up 'buffer' connected to the input-stream
    buffer.reset(dataBuffer.getData(), 0, dataBuffer.getLength());
  } finally {
    dataBuffer.close();
  }

  // Reset the codec
  filter.resetState();
}
