示例1: readBuffer
import org.apache.hadoop.io.compress.CompressionInputStream; //导入方法依赖的package包/类
/** 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();
}
