Class AccumuloBinaryConverter

java.lang.Object
  org.apache.pig.backend.hadoop.accumulo.AccumuloBinaryConverter

All Implemented Interfaces:

LoadCaster, LoadStoreCaster, StoreCaster

public class AccumuloBinaryConverter
extends Object
implements LoadStoreCaster

A LoadStoreCaster implementation which stores most type implementations as bytes generated from the toString representation with a UTF8 Charset. Pulled some implementations from the Accumulo Lexicoder implementations in 1.6.0.
