Virtual methods can be dispatched efficiently because the code for corresponding methods reside at the same entries in their respective virtual method tables (VMTs). To achieve efficient interface method dispatch, a fixed-sized interface method table (IMT) is associated with each class. Different implementations of the same interface method signature reside at the same entry in their respective IMTs. When a class implements two or more interface methods with the same IMT offset, a conflict resolution stub distinguishes between them at runtime. The resulting interface method dispatch is almost as cheap as its virtual counterpart.
