◆ operator=()

EggObject & EggObject::operator= ( const EggObject & copy)

Definition at line 42 of file eggObject.cxx.

◆ set_user_data()

void EggObject::set_user_data ( EggUserData * user_data)

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.
