Detailed Description

The expression_load_bogus class is used to represent a load that isn't a load - the address stays on the stack. This is used principally for strings, but may eventually have otjer uses.

Member Function Documentation

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

expression::pointer expression_load_bogus::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::pointer expression_load_bogus::assignment_expression_factory

(

const expression::pointer &

rhs

)

const [protected, virtual]

The assignment_expression_factory method is used by the assignment_expression method to build an assignment expression node.

The default implementation prints and error saying that the left hand side of the assignment is inappropriate.

Parameters:

rhs

The right hand side of the assignment ("this" is the left hand side).

Note:

The parser will delete this expression tree once the assignment tree has been manufactored. If you wish to keep using this tree, you will need to self() it.

Reimplemented from expression.

expression::pointer expression_load_bogus::strip_indirection

(

)

const [protected, virtual]

The strip_indirection method is used to obtain the address expression of an abstract indirection expression. This is used to pass variables by reference to functions and procedures.

The default implementation returns a NULL pointer, because the error has to be printer by the caller.

Reimplemented from expression.

expression_load_bogus& expression_load_bogus::operator=

(

const expression_load_bogus &

)

[private]

The assignment operator. Do not use.
