APPARATUS AND METHODS FOR VIRTUAL AND INTERFACE METHOD CALLS

摘要

Disclosed are apparatus and methods for calling software methods. A computing device can receive a request to call a software method of a class instance which can include an interface method table and a virtual method table (vtable). The interface method table can include interface method table entries, which can include a particular interface method table entry for a particular interface method of a software interface associated with the class instance. The particular interface method table entry can refer to the particular interface method. The vtable can include vtable entries, which can include a particular vtable entry for a particular virtual method associated with the class instance. The particular vtable entry can refer to the particular virtual method. The computing device can determine an entry point for the called software method based on the interface method table and/or the vtable. The computing device can call the called software method by executing instructions at the entry point.
