void ReferenceCount::local_object | ( | ) | [inline, inherited] |
This function should be called, once, immediately after creating a new instance of some ReferenceCount-derived object on the stack.
This allows the object to be passed to functions that will increment and decrement the object's reference count temporarily, and it will prevent the object from being deleted (inappropriately), when the reference count returns to zero. It actually achieves this by setting a large positive value in the reference count field.

void ReferenceCount::ref | ( | ) | const [inline, inherited] |
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.
This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.

void EggJointData::reparent_to | ( | EggJointData * | new_parent | ) | [inline] |
Indicates an intention to change the parent of this joint to the indicated joint, or NULL to remove it from the hierarchy.
The joint is not reparented immediately, but rather all of the joints are reparented at once when do_reparent() is called.

Returns true if the rest frames for different models differ in their initial value.

int EggJointData::score_reparent_to | ( | EggJointData * | new_parent, |

Computes a score >= 0 reflecting the similarity of the current joint's animation (in world space) to that of the indicated potential parent joint (in world space).
The lower the number, the more similar the motion, and the more suitable is the proposed parent-child relationship. Returns -1 if there is an error.

void EggObject::set_user_data | ( | EggUserData * | user_data | ) | [inherited] |
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.

bool ReferenceCount::unref | ( | ) | const [inline, virtual, inherited] |
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().
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.
This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.
The return value is true if the new reference count is nonzero, false if it is zero.
