An object's virtual method table will contain the addresses of the object's dynamically bound methods. Method calls are performed by fetching the method's address from the object's virtual method table. The virtual method table is the same for all objects belonging to the same class, and is therefore typically shared between them.
A single thread is dedicated to execute the methods of the object. Method calls from threads outside of the apartment are marshalled and automatically queued by the system (via Windows messaging). Thus, the COM run-time provides synchronization to ensure that each method call to the object is executed to completion before another is invoked.
The default form of dispatch is static. To get dynamic dispatch the programmer must declare a method as virtual. C++ compilers typically implement dynamic dispatch with a data structure called a virtual function table (vtable) that defines the name-to-implementation mapping for a given class as a set of member function pointers. This is purely ...
Departments or other top-level agencies, i.e., where the head of agency reports directly to the Governor (with the exception of the Education Department which is headed by the Regents of the University of the State of New York, and the Executive Department which is headed by the Governor.)
The flag of New York. The Government of the State of New York, headquartered at the New York State Capitol in Albany, encompasses the administrative structure of the U.S. state of New York, as established by the state's constitution. Analogously to the US federal government, it is composed of three branches: executive, legislative, and judicial.
Virtual functions allow a program to call methods that don't necessarily even exist at the moment the code is compiled. [citation needed] In C++, virtual methods are declared by prepending the virtual keyword to the function's declaration in the base class. This modifier is inherited by all implementations of that method in derived classes ...
Multiple dispatch or multimethods is a feature of some programming languages in which a function or method can be dynamically dispatched based on the run-time (dynamic) type or, in the more general case, some other attribute of more than one of its arguments. [1]
In C#, class methods, indexers, properties and events can all be overridden. Non-virtual or static methods cannot be overridden. The overridden base method must be virtual, abstract, or override. In addition to the modifiers that are used for method overriding, C# allows the hiding of an inherited property or method.
