◆ evalLeftToRight()

bool Bagel::CBagExpression::evalLeftToRight	(	bool	negFl = `false`,
		CBagVar &	result = `*_tempVar`
	)

Same as evaluate above except it evaluates left to right and preserves the value of the previous evaluation in the loop. Provides partial evaluation hierarchy support.

The documentation for this class was generated from the following file:
