expression_dereference::expression_dereference

(

const expression::pointer &

arg

)

The constructor.

expression_dereference::expression_dereference

Member Function Documentation

void expression_dereference::traversal

(

int

pprec

)

[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.

int expression_dereference::get_precedence

(

)

const [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_dereference::get_type

(

)

const [virtual]

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

Implements expression.

bool expression_dereference::is_lvalue

(

)

const [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_dereference::has_side_effect

(

)

const [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.

void expression_dereference::pre_order_traversal

(

int

pprec

)

[protected]

The pre_order_traversal method is called by the traversal method just before the operand is traversed.

Reimplemented in expression_dereference_pretty.

void expression_dereference::post_order_traversal

(

int

pprec

)

[protected]

The post_order_traversal method is called by the traversal method just after the operand is traversed.

Reimplemented in expression_dereference_pretty.

expression::pointer expression_dereference::get_operand

(

)

const [inline, protected]

Definition at line 72 of file dereference.h.

References operand.

bool expression_dereference::is_explicit

(

)

const [protected]

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

expression_dereference& expression_dereference::operator=

(

const expression_dereference &

)

[private]

The assignment operator. Do not use.
