Class Summary

Class	Description
JrubyAccumulatorEvalFunc	This class provides a bridge between Ruby classes that extend AccumulatorPigUdf and their execution in Pig.
JrubyAlgebraicEvalFunc<T>	This class provides the bridge between Ruby classes that extend the AlgebraicPigUdf "interface" by implementing an initial, intermed, and final method.
JrubyAlgebraicEvalFunc.AlgebraicFunctionWrapper<T>	This is a lightweight wrapper shell that registers information on the method being called, and provides the initializer that the static Algebraic classes (Initial, Intermed, Final) will use to execute.
JrubyAlgebraicEvalFunc.BagJrubyAlgebraicEvalFunc	Unlike EvalFuncs and Accumulators, the type must be known at compile time (ie it can't return Object), as Pig inspects the type and ensures that it is valid.

JrubyAlgebraicEvalFunc.IntegerJrubyAlgebraicEvalFunc.Final
JrubyAlgebraicEvalFunc.Intermed	This class invokes the intermed method on the given Ruby class.

JrubyAlgebraicEvalFunc.MapJrubyAlgebraicEvalFunc.Final
JrubyAlgebraicEvalFunc.TupleJrubyAlgebraicEvalFunc
JrubyAlgebraicEvalFunc.TupleJrubyAlgebraicEvalFunc.Final
JrubyEvalFunc	This class serves at the bridge between Ruby methods that are registered with and extend PigUdf, and their execution in Pig.
JrubyScriptEngine	Implementation of the script engine for Jruby, which facilitates the registration of scripts as UDFs, and also provides information (via the nested class RubyFunctions) on the registered functions.
PigJrubyLibrary	This class provides the ability to present to Ruby a library that was written in Java.
RubyDataBag	This provides a Ruby-esque way to interact with DataBag objects.
RubyDataByteArray	This class presents a native Ruby object for interacting with and manipulating DataByteArray objects.
RubySchema	This class encapsulated a native Schema object, and provides a more convenient interface for manipulating Schemas.
