Examples of ImmutableBytesWritable

org.apache.hadoop.hbase.io.ImmutableBytesWritable
A byte sequence that is usable as a key or value. Based on {@link org.apache.hadoop.io.BytesWritable} only this class is NOT resizableand DOES NOT distinguish between the size of the seqeunce and the current capacity as {@link org.apache.hadoop.io.BytesWritable} does. Hence itscomparatively 'immutable'. When creating a new instance of this class, the underlying byte [] is not copied, just referenced. The backing buffer is accessed when we go to serialize.
