java.lang.Object

org.apache.hadoop.hbase.io.hfile.bucket.TestByteBufferIOEngine.BufferGrabbingDeserializer

All Implemented Interfaces:

org.apache.hadoop.hbase.io.hfile.CacheableDeserializer<org.apache.hadoop.hbase.io.hfile.Cacheable>

Enclosing class:

TestByteBufferIOEngine

static class TestByteBufferIOEngine.BufferGrabbingDeserializer
extends Object
implements org.apache.hadoop.hbase.io.hfile.CacheableDeserializer<org.apache.hadoop.hbase.io.hfile.Cacheable>

A CacheableDeserializer implementation which just store reference to the ByteBuff to be deserialized. Use getDeserializedByteBuff() to get this reference.
