示例1: readKey

/** 
 * Analyze the key and fill the state assuming we know previous state.
 * Uses mark() and reset() in ByteBuffer to avoid moving the position.
 * <p>
 * This method overrides all the fields of this instance, except
 * {@link #prevOffset}, which is usually manipulated directly by encoders
 * and decoders.
 * @param in Buffer at the position where key starts
 * @param keyLength Length of key in bytes
 * @param valueLength Length of values in bytes
 * @param commonPrefix how many first bytes are common with previous KeyValue
 * @param previousState State from previous KeyValue
 */
void readKey(ByteBuffer in, int keyLength, int valueLength,
    int commonPrefix, CompressionState previousState) {
  this.keyLength = keyLength;
  this.valueLength = valueLength;

  // fill the state
  in.mark(); // mark beginning of key

  if (commonPrefix < KeyValue.ROW_LENGTH_SIZE) {
    rowLength = in.getShort();

    familyLength = in.get();
