void | signalObserversAndDelete (bool signalDelete, bool doDelete) const |
| |
|
void | deleteUsingDeleteHandler () const |
| |
Base class for providing reference counted objects.
◆ addObserver()
| void osg::Referenced::addObserver |
( |
Observer * |
observer | ) |
const |
Add a Observer that is observing this object, notify the Observer when this object gets deleted.
◆ getDeleteHandler()
◆ getGlobalReferencedMutex()
◆ getObserverSet()
Get the ObserverSet if one is attached, otherwise return NULL.
◆ getOrCreateObserverSet()
| ObserverSet* osg::Referenced::getOrCreateObserverSet |
( |
| ) |
const |
◆ getRefMutex()
Get the mutex used to ensure thread safety of ref()/unref().
◆ getThreadSafeReferenceCounting()
| static bool osg::Referenced::getThreadSafeReferenceCounting |
( |
| ) |
|
|
static |
Get whether reference counting is active.
◆ getThreadSafeRefUnref()
| bool osg::Referenced::getThreadSafeRefUnref |
( |
| ) |
const |
|
inline |
Get whether a mutex is used to ensure ref() and unref() are thread safe.
◆ ref()
| int osg::Referenced::ref |
( |
| ) |
const |
|
inline |
Increment the reference count by one, indicating that this object has another pointer which is referencing it.
◆ referenceCount()
| int osg::Referenced::referenceCount |
( |
| ) |
const |
|
inline |
Return the number of pointers currently referencing this object.
◆ removeObserver()
| void osg::Referenced::removeObserver |
( |
Observer * |
observer | ) |
const |
Remove Observer that is observing this object.
◆ setDeleteHandler()
| static void osg::Referenced::setDeleteHandler |
( |
DeleteHandler * |
handler | ) |
|
|
static |
Set a DeleteHandler to which deletion of all referenced counted objects will be delegated.
◆ setThreadSafeReferenceCounting()
| static void osg::Referenced::setThreadSafeReferenceCounting |
( |
bool |
enableThreadSafeReferenceCounting | ) |
|
|
static |
Set whether reference counting should use a mutex for thread safe reference counting.
◆ setThreadSafeRefUnref()
| virtual void osg::Referenced::setThreadSafeRefUnref |
( |
bool |
threadSafe | ) |
|
|
virtual |
Set whether to use a mutex to ensure ref() and unref() are thread safe.
Reimplemented in osg::StateSet, osg::Node, osgText::Text, osgText::GlyphTexture, osg::Drawable, osgText::TextBase, osgText::Glyph3D, osgSim::OverlayNode::OverlayData, osgText::Font, osgText::GlyphGeometry, osg::Group, osg::Object, osgSim::OverlayNode, osgText::Text3D, osg::LightSource, osg::Program, and osg::TexGenNode.
◆ unref()
| int osg::Referenced::unref |
( |
| ) |
const |
|
inline |
Decrement the reference count by one, indicating that a pointer to this object is no longer referencing it.
If the reference count goes to zero, it is assumed that this object is no longer referenced and is automatically deleted.
◆ unref_nodelete()
| int osg::Referenced::unref_nodelete |
( |
| ) |
const |
Decrement the reference count by one, indicating that a pointer to this object is no longer referencing it.
However, do not delete it, even if ref count goes to 0. Warning, unref_nodelete() should only be called if the user knows exactly who will be responsible for, one should prefer unref() over unref_nodelete() as the latter can lead to memory leaks.
