Object () | |
Construct an object. | |
Object (bool threadSafeRefUnref) | |
Object (const Object &, const CopyOp ©op=CopyOp::SHALLOW_COPY) | |
Copy constructor, optional CopyOp object can be used to control shallow vs deep copying of dynamic data. | |
virtual Object * | cloneType () const =0 |

virtual Object * | clone (const CopyOp &) const =0 |
Clone an object, with Object* return type. | |
virtual bool | isSameKindAs (const Object *) const |
virtual const char * | libraryName () const =0 |
return the name of the object's library. | |
virtual const char * | className () const =0 |
return the name of the object's class type. | |
virtual void | setThreadSafeRefUnref (bool threadSafe) |
Set whether to use a mutex to ensure ref() and unref() are thread safe. | |
virtual void | setName (const std::string &name) |
Set the name of object using C++ style string. | |
void | setName (const char *name) |
Set the name of object using a C style string. | |
const std::string & | getName () const |
Get the name of object. | |
void | setDataVariance (DataVariance dv) |
Set the data variance of this object. | |
DataVariance | getDataVariance () const |

void | setUserDataContainer (osg::UserDataContainer *udc) |
set the UserDataContainer object. | |
osg::UserDataContainer * | getUserDataContainer () |
get the UserDataContainer attached to this object. | |
const osg::UserDataContainer * | getUserDataContainer () const |
get the const UserDataContainer attached to this object. | |
osg::UserDataContainer * | getOrCreateUserDataContainer () |
Convinience method that returns the UserDataContainer, and if one doesn't already exist creates and assigns a DefaultUserDataContainer to the Object and then return this new UserDataContainer. | |
virtual void | setUserData (Referenced *obj) |
Set user data, data must be subclassed from Referenced to allow automatic memory handling. | |
virtual Referenced * | getUserData () |
Get user data. | |
virtual const Referenced * | getUserData () const |
Get const user data. | |
template<typename T > | |
bool | getUserValue (const std::string &name, T &value) const |
Convinience method that casts the named UserObject to osg::TemplateValueObject<T> and gets the value. | |
template<typename T > | |
void | setUserValue (const std::string &name, const T &value) |
Convinience method that creates the osg::TemplateValueObject<T> to store the specified value and adds it as a named UserObject. | |
virtual void | resizeGLObjectBuffers (unsigned int) |
Resize any per context GLObject buffers to specified size. | |
virtual void | releaseGLObjects (osg::State *=0) const |
If State is non-zero, this function releases any associated OpenGL objects for the specified graphics context. | |

Referenced (const Referenced &) | |
Referenced & | operator= (const Referenced &) |
bool | getThreadSafeRefUnref () const |

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. |
convience update callback class that can be attached to StateAttribute (such as Textures) to ensure that the Image::update(NodeVisitor*) method is called during the update traversal.
This callback is automatically attached when Image::requiresUpdateCall() is true (it's false by default.)
