ByteRangeSet (Apache HBase 1.2.12 API)

java.lang.Object
- org.apache.hadoop.hbase.util.byterange.ByteRangeSet

Direct Known Subclasses:

ByteRangeHashSet, ByteRangeTreeSet
```
@InterfaceAudience.Private
public abstract class ByteRangeSet
extends Object
```
Performance oriented class for de-duping and storing arbitrary byte[]'s arriving in non-sorted order. Appends individual byte[]'s to a single big byte[] to avoid overhead and garbage.
Current implementations are ByteRangeHashSet and ByteRangeTreeSet, but other options might be a trie-oriented ByteRangeTrieSet, etc
