Uses of HFileBlock in org.apache.hadoop.hbase.io.hfile

Subclasses of HFileBlock in org.apache.hadoop.hbase.io.hfile

Modifier and Type	Class and Description
class	ExclusiveMemHFileBlock The ByteBuffAllocator won't allocate pooled heap ByteBuff now; at the same time, if allocate an off-heap ByteBuff from allocator, then it must be a pooled one.
class	SharedMemHFileBlock The ByteBuffAllocator won't allocate pooled heap ByteBuff now; at the same time, if allocate an off-heap ByteBuff from allocator, then it must be a pooled one.
