Class DynamicFunctionFactory

java.lang.Object
hussam.math.operations.factory.OperatorFactoryImpl<Function>
hussam.math.operations.extra.CustomFunctionFactory
hussam.math.operations.extra.DynamicFunctionFactory

All Implemented Interfaces:: OperatorFactory<Function>, java.io.Serializable, java.lang.Comparable<Operator>

public class DynamicFunctionFactory
extends CustomFunctionFactory
extends CustomFunctionFactory

This factory creates CustomFunctions that have thies expression changed. for example, if you create two CustomFunction from this factory, you can change the expression of both functions by called the setExpression of this factory. you can notice that the setExpression(String) used is overriden to be public. This is a very helpful class, to have many created functions to have one expression to be sharred among all.
