Member Function Documentation

void expression_boolean_pretty::traversal

(

int

pprec

)

[protected, virtual]

The traversal method may be used to traverse each of the declaractions in the list.

Parameters:

pprec

The precedence of the parent expression node.

Implements expression.

void expression_boolean_pretty::logical_traversal	(	int	pprec,
		label::pointer &	true_branch,
		label::pointer &	false_branch,
		bool	fall_through_preference
	)			[protected]

Reimplemented from expression_boolean.

expression::pointer expression_boolean_pretty::optimize

(

)

const [protected, virtual]

The optimize method may be used to evaluate constant expressions, or substitute more efficient expressions.

This is intended to be called by the translator:: expression_statement method, or similar, where the expression is in its final form, and will get no deeper. In other words, when all available information has been provided.

There is no default implementation, even though most optimize implementations return self(), because this gives the compiler no opportunity to remind the authors of new classes that they have forgotten something.

Returns:

If the expression tree is not constant, or it is already as reduced as it can get, it returns itself. Otherwise, it returns a new expression node.

Implements expression.

expression_boolean_pretty& expression_boolean_pretty::operator=

(

const expression_boolean_pretty &

)

[private]

The assignment operator.
