示例1: writeKV
import org.apache.hadoop.hbase.KeyValue; //导入方法依赖的package包/类
/**
* Compresses and writes ourKV to out, a DataOutput.
*
* @param out the DataOutput
* @param keyVal the KV to compress and write
* @param writeContext the compressionContext to use.
* @throws IOException
*/
public static void writeKV(final DataOutput out, KeyValue keyVal,
CompressionContext writeContext) throws IOException {
byte[] backingArray = keyVal.getBuffer();
int offset = keyVal.getOffset();
// we first write the KeyValue infrastructure as VInts.
WritableUtils.writeVInt(out, keyVal.getKeyLength());
WritableUtils.writeVInt(out, keyVal.getValueLength());
WritableUtils.writeVInt(out, keyVal.getTagsLength());
// now we write the row key, as the row key is likely to be repeated
// We save space only if we attempt to compress elements with duplicates
Compressor.writeCompressed(keyVal.getBuffer(), keyVal.getRowOffset(),
keyVal.getRowLength(), out, writeContext.rowDict);
// now family, if it exists. if it doesn't, we write a 0 length array.
Compressor.writeCompressed(keyVal.getBuffer(), keyVal.getFamilyOffset(),
keyVal.getFamilyLength(), out, writeContext.familyDict);
// qualifier next
Compressor.writeCompressed(keyVal.getBuffer(), keyVal.getQualifierOffset(),
keyVal.getQualifierLength(), out,
writeContext.qualifierDict);
// now we write the rest uncompressed
int pos = keyVal.getTimestampOffset();
int remainingLength = keyVal.getLength() + offset - (pos);
out.write(backingArray, pos, remainingLength);
