Methods of TypedObject:

getClassType
static TypeHandle GeomDrawCallbackData::get_class_type(void);

Undocumented function.

getForce
bool GeomDrawCallbackData::get_force(void) const;

Description: Returns true if any required data should be forced into memory if necessary to render the object, or false if the object should be omitted if some of the data is not available (at least until the data becomes available later).

getGsg
GraphicsStateGuardianBase *GeomDrawCallbackData::get_gsg(void) const;

Description: Returns a pointer to the current GSG.

getLostState
bool GeomDrawCallbackData::get_lost_state(void) const;

Description: Returns the lost_state flag. See set_lost_state().

getObject
CullableObject *GeomDrawCallbackData::get_object(void) const;

Description: Returns a pointer to the particular object that is being drawn.

setLostState
void GeomDrawCallbackData::set_lost_state(bool lost_state);

Description: Sets the lost_state flag. If this is true, the callback does not have to be quite so careful to clean up after itself; Panda will assume that the graphics state is in an unknown state after the callback has finished, and will issue all the necessary calls to restore it. If this is false, Panda will assume the callback will leave the graphics state exactly as it came in, and won't bother to try to restore it. The default is true.

getClassType
static TypeHandle CallbackData::get_class_type(void);

Undocumented function.

output
virtual void CallbackData::output(ostream &out) const;

Description:

upcall
virtual void CallbackData::upcall(void);

Description: You should make this call during the callback if you want to continue the normal function that would have been done in the absence of a callback.

getClassType
static TypeHandle TypedObject::get_class_type(void);

Undocumented function.

getType
virtual TypeHandle TypedObject::get_type(void) const = 0;

Derived classes should override this function to return get_class_type().

getTypeIndex
int TypedObject::get_type_index(void) const;

Description: 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().

isExactType
bool TypedObject::is_exact_type(TypeHandle handle) const;

Description: Returns true if the current object is the indicated type exactly.

isOfType
bool TypedObject::is_of_type(TypeHandle handle) const;

Description: Returns true if the current object is or derives from the indicated type.
