createOpNode

public OpNode createOpNode(Node right,
                           Node left)

Creates a new instace of this node type.

Overrides:

createOpNode in class OpNode

createOpNode

public OpNode createOpNode(java.util.Stack operands)
                    throws OperandException

Creates a new node using the factory pattern. New node is initialized using the operands from the stack. Plus node is a binary operand node (takes 2 elements from the stack)

Overrides:

createOpNode in class OpNode

Parameters:

operands - Stack containing operands.

Returns:

Newly created OpNode initialized.

Throws:

OperandException - Throws OperandException if there aren't enough operands on the stack.

main

public static void main(java.lang.String[] args)

Test function for PlusOpNode

Parameters:

args - command line arguments
