Method Detail

evaluateInternal

protected java.lang.Object evaluateInternal(java.lang.String aLeftOperand,
                                            java.lang.String aRightOperand)

Description copied from class: OperatorNode

Must be implemented by subclasses to implement the actual evaluation of this node. It will get evaluated and converted operands and needs to return the result of the evaluation.

Specified by:

evaluateInternal in class OperatorNode<java.lang.String,java.lang.String>

Parameters:

aLeftOperand - the evaluated left operand

aRightOperand - the evaluated right operand

Returns:

the result of the evaluation
