BufferedDataBlockEncoder.ClonedSeekerState (Apache HBase 1.2.12 API)

java.lang.Object
- org.apache.hadoop.hbase.io.encoding.BufferedDataBlockEncoder.ClonedSeekerState

All Implemented Interfaces:

Cell, HeapSize, SettableSequenceId

Enclosing class:

BufferedDataBlockEncoder
```
protected static class BufferedDataBlockEncoder.ClonedSeekerState
extends Object
implements Cell, HeapSize, SettableSequenceId
```
Copies only the key part of the keybuffer by doing a deep copy and passes the seeker state members for taking a clone. Note that the value byte[] part is still pointing to the currentBuffer and the represented by the valueOffset and valueLength
