These methods are similar in concept to C++ nonstatic member functions (that is, C++ functions that are not virtual member functions and are not static member functions). Nonstatic methods are normally invoked using offset resolution, but all three kinds of method resolution are applicable to nonstatic methods. When the SOMobjects language bindings are used to implement a class, the SOM IDL nonstatic modifier is used to indicate that a given method is nonstatic.
Like static methods, nonstatic methods are given individual positions in method tables. However, nonstatic methods cannot be overridden. Instead, descendants of a class that introduces a nonstatic method can use the SOM IDL reintroduce modifier to "hide" the original nonstatic method with another (nonstatic or static) method of the same name. When a nonstatic method is resolved, selection of the specific method procedure is determined by the interface that is used to access the method.
