org.apache.accumulo.core.client.lexicoder.impl.AbstractLexicoder<Long>

org.apache.accumulo.core.client.lexicoder.ULongLexicoder

All Implemented Interfaces:

Encoder<Long>, Lexicoder<Long>, org.apache.accumulo.core.iterators.TypedValueCombiner.Encoder<Long>

Direct Known Subclasses:

public class ULongLexicoder
extends org.apache.accumulo.core.client.lexicoder.impl.AbstractLexicoder<Long>
implements Lexicoder<Long>

Unsigned long lexicoder. The lexicographic encoding sorts first 0l and -1l last. This encoding does not correspond to the sort of Long because it does not consider the sign bit. If Java had an unsigned long type, this encoder would correspond to its sort order.

Since:

1.6.0
