| Sets the user data associated with this object. This may be any EggUserData-derived object. The egg library will do nothing with this pointer, except to hold its reference count and return the pointer on request. More...

TypeHandle | getType () |
| Derived classes should override this function to return get_class_type(). More...

int | getTypeIndex () |
| Returns the internal index number associated with this object's TypeHandle, a unique number for each different type. This is equivalent to get_type().get_index(). More...

Public Member Functions inherited from ReferenceCount |
int | getRefCount () |
| Returns the current reference count. More...
|
|
| ref () |
| Explicitly increments the reference count. User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically. More...

|
bool | testRefCountIntegrity () |
| Does some easy checks to make sure that the reference count isn't completely bogus. Returns true if ok, false otherwise. More...
|
|
bool | testRefCountNonzero () |
| Does some easy checks to make sure that the reference count isn't zero, or completely bogus. Returns true if ok, false otherwise. More...
|
|
bool | unref () |
| Explicitly decrements the reference count. Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic.) However, see the helper function unref_delete(). More...

The highest-level base class in the egg directory. (Almost) all things egg inherit from this.
Sets the user data associated with this object. This may be any EggUserData-derived object. The egg library will do nothing with this pointer, except to hold its reference count and return the pointer on request.
The EggObject maintains multiple different EggUserData pointers, one for each unique type (as reported by get_type()). If you know that only one type of EggUserData object will be added in your application, you may use the query functions that accept no parameters, but it is recommended that in general you pass in the type of your particular user data, to allow multiple applications to coexist in the same egg data.
This pointer is also copied by the copy assignment operator and copy constructor.
