Detailed Description

Almost all simple (non composite) operators will be constructed by specifying number of operands, operands and the text representation of the operator.

This is an implementation of Composite design pattern where leaves and composites share the same interface.

Constructor & Destructor Documentation

pdfobjects::SimpleGenericOperator::SimpleGenericOperator	(	const char *	opTxt,
		const size_t	numOper,
		Operands &	opers
	)

Constructor. Create it as a standalone object. Prev and Next are not valid.

Parameters:

	opTxt	Operator name text representation.
	numOper	(Maximum) Number of operands.
	opers	This is a stack of operands from which we take number specified by numOper or while any operand left.
