org.apache.hadoop.hbase.codec.prefixtree.PrefixTreeCodec

所有已实现的接口:

DataBlockEncoder

已过时。

Since 1.2.7. Will be removed in 2.0.0. Write the dev list if you would like to take on the maintainence of this facility.

@Deprecated
@InterfaceAudience.Private
public class PrefixTreeCodec
extends Object
implements DataBlockEncoder

This class is created via reflection in DataBlockEncoding enum. Update the enum if class name or package changes.

PrefixTreeDataBlockEncoder implementation of DataBlockEncoder. This is the primary entry point for PrefixTree encoding and decoding. Encoding is delegated to instances of PrefixTreeEncoder, and decoding is delegated to instances of CellSearcher. Encoder and decoder instances are created and recycled by static PtEncoderFactory and PtDecoderFactory.
