Dynamic dispatch method
WebThe call must be dispatched to the right function dynamically(that is, at run time) instead. Implementation[edit] An object's virtual method table will contain the addressesof the object's dynamically bound methods. Method calls are performed by fetching the method's address from the object's virtual method table. WebJan 19, 2024 · Static vs. Dynamic Dispatch. Dynamic dispatch and static dispatch are two different mechanisms used in programming languages to determine which method or function to call. Dynamic dispatch, also known as runtime polymorphism or late binding, is a mechanism where the decision of which method or function to call is made at runtime, …

WebJan 30, 2012 · · Dynamic dispatch – when a method is invoked on an object, the object itself determines what code gets executed by looking up the method at run time in a table associated with the object. This feature distinguishes an object from an abstract data type (or module), which has a fixed (static) implementation of the operations for all instances ... WebFeb 10, 2009 · Dynamic Dispatch - The actual method group/signature/override chain is bound at compile time. The method called is dependent upon the actual runtime type of the object but no actual interpretation occurs. It will still be a version of the statically bound method. Here is an example in C#.

For every class that defines or inherits virtual functions the compiler creates a virtual table. The virtual table stores a pointer to the most specific definition of each virtual function. For every class that has a vtable, the compiler adds an extra member to the class ...
