typedef struct _heapobject heapobject

Heap structure when allocating rave objects.

Function Documentation

RaveCoreObject_bind()

void RaveCoreObject_bind	(	RaveCoreObject *	src,
		void *	bindingData )

Sets the binding data field, useful when for example associating this object with another object in order to manage objects from python or other languages.

Do not use this function directly but use the macros for binding instead.

Parameters

[in]	src	- this object
[in]	bindingData	- the associated object (or similar)

RaveCoreObject_clone()

RaveCoreObject * RaveCoreObject_clone	(	RaveCoreObject *	src,
		const char *	filename,
		int	lineno )

Creates a clone of the provided object by using the types copyconstructor (if there is any).

Parameters

[in]	src	- the object to be cloned
[in]	filename	- the filename that this operation was performed in
[in]	lineno	- the linenumber that this operation was performed in

Returns

a pointer to the cloned object

RaveCoreObject_copy()

RaveCoreObject * RaveCoreObject_copy	(	RaveCoreObject *	src,
		const char *	filename,
		int	lineno )

Increments the reference counter and returns a pointer to the provided object.

Parameters

[in]	src	- the object to be copied
[in]	filename	- the filename that this operation was performed in
[in]	lineno	- the linenumber that this operation was performed in

Returns

a pointer to the copied object

RaveCoreObject_getBindingData()

void * RaveCoreObject_getBindingData

(

RaveCoreObject *

src

)

Returns the extra data.

Do not use this function directly but use the macros for binding objects instead.

Parameters

[in]

src

- this object

Returns

the binding data or NULL if none.

RaveCoreObject_getRefCount()

int RaveCoreObject_getRefCount

(

RaveCoreObject *

src

)

Returns the current reference count.

Parameters

[in]

src

- the the object that should be queried for reference count

Returns

the reference count.

RaveCoreObject_getTrackObjects()

int RaveCoreObject_getTrackObjects

(

void

)

Returns

if object creation / destruction is tracked.

RaveCoreObject_isCloneable()

int RaveCoreObject_isCloneable

(

RaveCoreObject *

src

)

Returns if this object is possible to clone or not.

Parameters

[in]

src

- the rave core object

Returns

1 if the object is possible to clone.

RaveCoreObject_new()

RaveCoreObject * RaveCoreObject_new	(	RaveCoreObjectType *	type,
		const char *	filename,
		int	lineno )

Creates a new instance of the provided type.

Parameters

[in]	type	- the object type
[in]	filename	- the filename that this allocation was performed in
[in]	lineno	- the linenumber that this allocation was performed in

Returns

a new instance

RaveCoreObject_printCurrentObjectStatus()

void RaveCoreObject_printCurrentObjectStatus

(

void

)

Print current status of object creation.

RaveCoreObject_printStatistics()

void RaveCoreObject_printStatistics

(

void

)

Prints the rave object statistics.

RaveCoreObject_release()

void RaveCoreObject_release	(	RaveCoreObject *	obj,
		const char *	filename,
		int	lineno )

Decrements the reference counter and if reference counts gets to 0, the destructor that was provided when creating the instance will be called.

Note, regardless on if and how the destructor has been implemented, the object will be freed.

Parameters

[in]	obj	- the object to release (including the object itself)
[in]	filename	- the filename that this operation was performed in
[in]	lineno	- the linenumber that this operation was performed in

RaveCoreObject_setTrackObjects()

void RaveCoreObject_setTrackObjects

(

int

track

)

Will track object creation and destruction.

Parameters

[in]

track

- if object creation / destruction should be tracked

RaveCoreObject_unbind()

void RaveCoreObject_unbind	(	RaveCoreObject *	src,
		void *	bindingData )

Removes the binding from the rave object.

Do not use this function directly but use the macros for binding instead. If bindingData != the stored binding data nothing will happen.

Parameters

[in]	src	- this object
[in]	bindingData	- the binding to remove
