Uses of AccumulatorEvalFunc in org.apache.pig

Subclasses of AccumulatorEvalFunc in org.apache.pig

class	AlgebraicEvalFunc<T> This class is used to provide a free implementation of the Accumulator interface and EvalFunc class in the case of an Algebraic function.
class	IteratingAccumulatorEvalFunc<T> This class provides a much more intuitive way to write Accumulator UDFs. For example, you could express IsEmpty as follows:

class	JrubyAccumulatorEvalFunc This class provides a bridge between Ruby classes that extend AccumulatorPigUdf and their execution in Pig.
class	JrubyAlgebraicEvalFunc<T> This class provides the bridge between Ruby classes that extend the AlgebraicPigUdf "interface" by implementing an initial, intermed, and final method.
