run

public void run(java.util.Stack<java.lang.Object> s)
         throws EvaluationException

Description copied from class: PostfixMathCommand

Throws an exception because this method should never be called under normal circumstances. Each function should use it's own run() method for evaluating the function. This includes popping off the parameters from the stack, and pushing the result back on the stack.

Specified by:

run in interface PostfixMathCommandI

Overrides:

run in class PostfixMathCommand

Parameters:

s - arguments for function

Throws:

EvaluationException - if function cannot be evaluated
