Public Member Functions inherited from osg::Referenced | |
Referenced () | |
Referenced (bool threadSafeRefUnref) | |
Deprecated, Referenced is now always uses thread safe ref/unref, use default Referenced() constructor instead. | |
Referenced (const Referenced &) | |
Referenced & | operator= (const Referenced &) |
virtual void | setThreadSafeRefUnref (bool) |
Deprecated, Referenced is always theadsafe so there method now has no effect and does not need to be called. | |
bool | getThreadSafeRefUnref () const |
Get whether a mutex is used to ensure ref() and unref() are thread safe. | |
OpenThreads::Mutex * | getRefMutex () const |
Get the mutex used to ensure thread safety of ref()/unref(). | |
int | ref () const |
Increment the reference count by one, indicating that this object has another pointer which is referencing it. | |
int | unref () const |
Decrement the reference count by one, indicating that a pointer to this object is no longer referencing it. | |
int | unref_nodelete () const |
Decrement the reference count by one, indicating that a pointer to this object is no longer referencing it. | |
int | referenceCount () const |
Return the number of pointers currently referencing this object. | |
ObserverSet * | getObserverSet () const |
Get the ObserverSet if one is attached, otherwise return NULL. | |
ObserverSet * | getOrCreateObserverSet () const |
Get the ObserverSet if one is attached, otherwise create an ObserverSet, attach it, then return this newly created ObserverSet. | |
void | addObserver (Observer *observer) const |
Add a Observer that is observing this object, notify the Observer when this object gets deleted. | |
void | removeObserver (Observer *observer) const |
Remove Observer that is observing this object. |

|
protectedvirtual |
|
virtual |
implementation of the actual creation of an GL object - subclasses from GLObjectManager must implement the appropriate GL calls.
|
virtual |
Do a GL delete all OpenGL objects.
Note, must be called from a thread which has current the graphics context associated with contextID.
Implements osg::GraphicsObjectManager.
|
pure virtual |
implementation of the actual deletion of an GL object - subclasses from GLObjectManager must implement the appropriate GL calls.
Implemented in osg::GLFrameBufferObjectManager, and osg::GLRenderBufferManager.
|
virtual |
Discard all OpenGL objects.
Note, unlike deleteAllGLjects discard does not do any OpenGL calls so can be called from any thread, but as a consequence it also doesn't remove the associated OpenGL resource so discard should only be called when the associated graphics context is being/has been closed.
Implements osg::GraphicsObjectManager.
|
virtual |
Flush all deleted OpenGL objects.
Note, must be called from a thread which has current the graphics context associated with contextID.
Implements osg::GraphicsObjectManager.
|
virtual |
Flush all deleted OpenGL objects within the specified availableTime.
Note, must be called from a thread which has current the graphics context associated with contextID.
Implements osg::GraphicsObjectManager.
|
virtual |
schedule a GL object for deletion by the graphics thread.
