Detailed Description

If the type opcode is set to type_class the type represents class types.

A list of fields and methods is associated with a class. Further a class can inherit from and bequest to other classes.

The following attributes are private to this type kind:

• member: All entities belonging to this class. This are method entities which have type_method or fields that can have any of the following type kinds: type_class, type_struct, type_union, type_array, type_pointer, type_primitive.

The following two are dynamic lists that can be grown with an "add_" function, but not shrinked:

• subtypes: A list of direct subclasses.
• supertypes: A list of direct superclasses.

Macro Definition Documentation

#define INVALID_MEMBER_INDEX   ((size_t)-1)

Special index returned when get_class_member_index() cannot find a member.

This index is never used for actual members.

Function Documentation

void add_class_subtype	(	ir_type *	clss,
		ir_type *	subtype
	)

Adds subtype as subtype to clss.

Checks whether clss is a supertype of subtype. If not adds also clss as supertype to subtype.

void add_class_supertype	(	ir_type *	clss,
		ir_type *	supertype
	)

Adds supertype as supertype to class.

Checks whether clss is a subtype of supertype. If not adds also clss as subtype to supertype.

ir_entity* get_class_member	(	const ir_type *	clss,
		size_t	pos
	)

Returns the member at position pos, 0 <= pos < n_member.

size_t get_class_member_index	(	ir_type const *	clss,
		ir_entity const *	mem
	)

Returns index of mem in clss, INVALID_MEMBER_INDEX if not contained.

size_t get_class_n_members

(

const ir_type *

clss

)

Returns the number of members of this class.

size_t get_class_n_subtypes

(

const ir_type *

clss

)

Returns the number of subtypes.

size_t get_class_n_supertypes

(

const ir_type *

clss

)

Returns the number of supertypes.

ir_type* get_class_subtype	(	const ir_type *	clss,
		size_t	pos
	)

Returns the subtype at position pos, 0 <= pos < n_subtype.

size_t get_class_subtype_index	(	const ir_type *	clss,
		const ir_type *	subclass
	)

Returns the index to access subclass as subtype of class.

If subclass is no direct subtype of class returns -1.

ir_type* get_class_supertype	(	const ir_type *	clss,
		size_t	pos
	)

Returns the supertype at position pos, 0 <= pos < n_supertype.

size_t get_class_supertype_index	(	const ir_type *	clss,
		const ir_type *	super_clss
	)

Returns the index to access superclass as supertype of class.

If superclass is no direct supertype of class returns -1.

int is_Class_type

(

const ir_type *

clss

)

Returns true if a type is a class type.

ir_type* new_type_class

(

ident *

name

)

Creates a new class type.

void remove_class_subtype	(	ir_type *	clss,
		ir_type *	subtype
	)

Finds subtype in the list of subtypes and removes it.

void remove_class_supertype	(	ir_type *	clss,
		ir_type *	supertype
	)

Finds supertype in the list of supertypes and removes it.

void set_class_subtype	(	ir_type *	clss,
		ir_type *	subtype,
		size_t	pos
	)

Sets the subtype at position pos, 0 <= pos < n_subtype.

Does not set the corresponding supertype relation for subtype: this might be a different position!

void set_class_supertype	(	ir_type *	clss,
		ir_type *	supertype,
		size_t	pos
	)

Sets the supertype at position pos, 0 <= pos < n_supertype.

Does not set the corresponding subtype relation for supertype: this might be at a different position!
