// Function: MaterialPool::get_material
|
|
// Access: Public, Static
|
|
// Description: Returns a Material pointer that represents the
|
|
// same material described by temp, except that it is a
|
|
// shared pointer.
|
|
//
|
|
// Each call to get_material() passing an equivalent
|
|
// Material pointer will return the same shared pointer.
|
|
//
|
|
// If you modify the shared pointer, it will
|
|
// automatically disassociate it from the pool.
|
|
//
|
|
// Also, the return value may be a different pointer
|
|
// than that passed in, or it may be the same pointer.
|
|
// In either case, the passed in pointer has now been
|
|
// sacrificed to the greater good and should not be used
|
|
// again (like any other PointerTo, it will be freed
|
|
// when the last reference count is removed).
