expression_load_address::expression_load_address

Member Function Documentation

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

int expression_load_address::get_precedence

(

)

const [protected, virtual]

The get_precedence method is used to obtain the precedence of this expression node.

The highest precedence has the highest absolute value, the lowest precedence gets the lowest absolute value.

Implements expression.

type::pointer expression_load_address::get_type

(

)

const [protected, virtual]

The get_type method is used to get the type of this expression.

Implements expression.

bool expression_load_address::is_lvalue

(

)

const [protected, virtual]

The is_lvalue method is used to determine whether or not this expression is suitable to appear on the left hand side of an assignment expression.

Implements expression.

side_effect_t expression_load_address::has_side_effect

(

)

const [protected, virtual]

The has_side_effect method is used to determine if an expression has any effect. It is used by the parse to produce "statement with no effect" warnings.

Implements expression.

expression::pointer expression_load_address::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_load_address& expression_load_address::operator=

(

const expression_load_address &

)

[private]

The assignment operator.
