Virtual function information

Pascal, a virtual function or virtual method is an inheritable and overridable function or method that is dispatched dynamically. Virtual functions are an...

In computer programming, a virtual method table (VMT), virtual function table, virtual call table, dispatch table, vtable, or vftable is a mechanism used...

Network functions virtualization (NFV) is a network architecture concept that leverages IT virtualization technologies to virtualize entire classes of...
