Detailed Description

An ExpressionNode that handles exponentiation.

The node holds a base and an exponent and calulates base^exponent

Constructor & Destructor Documentation

uk.co.cogitolearning.cogpar.ExponentiationExpressionNode.ExponentiationExpressionNode	(	ExpressionNode	base,
		ExpressionNode	exponent
	)

Construct the ExponentiationExpressionNode with base and exponent.

Parameters

base	the node containing the base
exponent	the node containing the exponent

Member Function Documentation

void uk.co.cogitolearning.cogpar.ExponentiationExpressionNode.accept

(

ExpressionNodeVisitor

visitor

)

Implementation of the visitor design pattern.

Calls visit on the visitor and then passes the visitor on to the accept method of the base and the exponent.

Parameters

visitor

the visitor
