Function Documentation

build_class_identifier()

static exprt build_class_identifier ( const exprt &  src, const namespacet &  ns  )

static

parameters: Struct expression

Returns

Member expression giving the clsid field of the input, or its parent, grandparent, etc.

Definition at line 22 of file class_identifier.cpp.

get_class_identifier_field()

exprt get_class_identifier_field	(	const exprt &	this_expr_in,
		const struct_tag_typet &	suggested_type,
		const namespacet &	ns
	)

parameters: Pointer expression of any pointer type, including void*,

and a recommended access type if the pointer is void-typed.

Returns

Member expression to access a class identifier, as above.

Definition at line 57 of file class_identifier.cpp.

set_class_identifier()

void set_class_identifier	(	struct_exprt &	expr,
		const namespacet &	ns,
		const struct_tag_typet &	class_type
	)

If expr has its components filled in then sets the @class_identifier member of the struct.

Remarks

Follows through base class members until it gets to the object type that contains the @class_identifier member

Parameters

expr	An expression that represents a struct
ns	The namespace used to resolve symbol references in the type of the struct
class_type	A symbol whose identifier is the name of the class
