This stores a pointer from an EggJointData or EggSliderData object back to the referencing data in an egg file.
One of these objects corresponds to each model appearing in an egg file, and may reference either a single node, or a table, or a slew of vertices and primitives, depending on the type of data stored.
This is just an abstract base class. The actual details are stored in the various subclasses.

void EggBackPointer::extend_to | ( | int | num_frames | ) | [virtual] |

bool EggBackPointer::has_vertices | ( | ) | const [virtual] |
Returns true if there are any vertices referenced by the node this points to, false otherwise.
For certain kinds of back pointers (e.g. table animation entries), this is always false.

static void EggBackPointer::init_type | ( | ) | [inline, static] |
This function is declared non-inline to work around a compiler bug in g++ 2.96.
Making it inline seems to cause problems in the optimizer.
Reimplemented from TypedObject.

Applies the indicated name change to the egg file.
