Public Member Functions | |
virtual const char * | className () const |
virtual void | init (ViewDependentShadowTechnique *st, osgUtil::CullVisitor *cv) |
Method called upon ViewData instance to initialize internal variables. | |
virtual void | cull () |
Method called by ViewDependentShadowTechnique to allow ViewData do the hard work computing shadows for its associated view. | |
virtual void | dirty (bool flag) |
Dirty is called by parent ViewDependentShadowTechnique to force update of resources after some of them were modified in parent technique. | |
ViewData () | |
Simple constructor zeroing all variables. | |
![]() | |
Referenced () | |
Referenced (bool threadSafeRefUnref) | |
Referenced (const Referenced &) | |
Referenced & | operator= (const Referenced &) |
virtual void | setThreadSafeRefUnref (bool threadSafe) |
Set whether to use a mutex to ensure ref() and unref() are thread safe. | |
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 referencing it. | |
int | unref_nodelete () const |
Decrement the reference count by one, indicating that a pointer to this object is 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. |
Public Attributes | |
OpenThreads::Mutex | _mutex |
Mutex used to guard _dirty flag from override in case when parent technique calls dirty() simultaneously with ViewData while it is updating resources inside init method. | |
bool | _dirty |
Dirty flag tells this instance to update its resources. | |
osg::observer_ptr < osgUtil::CullVisitor > | _cv |
View's CullVisitor associated with this ViewData instance. | |
osg::observer_ptr < ViewDependentShadowTechnique > | _st |
Parent ViewDependentShadowTechnique. |
Additional Inherited Members | |
![]() | |
static OpenThreads::Mutex * | getGlobalReferencedMutex () |
Get the optional global Referenced mutex, this can be shared between all osg::Referenced. | |
static void | setThreadSafeReferenceCounting (bool enableThreadSafeReferenceCounting) |
Set whether reference counting should use a mutex for thread safe reference counting. | |
static bool | getThreadSafeReferenceCounting () |
Get whether reference counting is active. | |
static void | setDeleteHandler (DeleteHandler *handler) |
Set a DeleteHandler to which deletion of all referenced counted objects will be delegated. | |
static DeleteHandler * | getDeleteHandler () |
Get a DeleteHandler. | |
![]() | |
virtual | ~Referenced () |
void | signalObserversAndDelete (bool signalDelete, bool doDelete) const |
void | deleteUsingDeleteHandler () const |
![]() | |
OpenThreads::AtomicPtr | _observerSet |
OpenThreads::Atomic | _refCount |
Base container class for view dependent shadow resources.
Techniques based on ViewDependentShadowTechnique will usually define similar struct and derive it from ViewData to contain their specufic resources.
|
inline |
Simple constructor zeroing all variables.
Reimplemented in osgShadow::MinimalDrawBoundsShadowMap::ViewData.
|
inlinevirtual |
|
virtual |
Method called by ViewDependentShadowTechnique to allow ViewData do the hard work computing shadows for its associated view.
Reimplemented in osgShadow::StandardShadowMap::ViewData, and osgShadow::DebugShadowMap::ViewData.

View's CullVisitor associated with this ViewData instance.
bool osgShadow::ViewDependentShadowTechnique::ViewData::_dirty |
Dirty flag tells this instance to update its resources.
OpenThreads::Mutex osgShadow::ViewDependentShadowTechnique::ViewData::_mutex |
osg::observer_ptr< ViewDependentShadowTechnique > osgShadow::ViewDependentShadowTechnique::ViewData::_st |
Parent ViewDependentShadowTechnique.
