Package org.nfunk.jep.function

Provides function and operator classes.

Description

Interface Summary

CallbackEvaluationI	Functions which require greater control over their evaluation should implement this interface.
LValueI
PostfixMathCommandI	All function classes must implement this interface to ensure that the run() method is implemented.
SpecialEvaluationI	Deprecated. The interface CallbackEvaluationI should generally be used instead as its simpler and allows different evaluation schemes to be used.

Class Summary
