Uses of AccumulatorEvalFunc in org.apache.pig

Subclasses of AccumulatorEvalFunc in org.apache.pig

Modifier and Type	Class and Description
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:
