Dispatch table
In computer science, a dispatch table is a table of pointers or memory addresses to functions or methods. Use of such a table is a common technique when implementing late binding in object-oriented programming.
The following shows one way to implement a dispatch table in Perl, using a hash to store references to code (also known as function pointers).
Running this Perl program as perl greet -h will produce "hello", and running it as perl greet -g will produce "goodbye".
Following is a demo of implementing a dispatch table in JavaScript:
In object-oriented programming languages that support virtual methods, the compiler will automatically create a dispatch table for each object of a class containing virtual methods. This table is called a virtual method table or vtable, and every call to a virtual method is dispatched through the vtable.
