Method stub

In the following example pseudocode, the function ReadThermometer returns a particular value even though ultimately it is supposed to read a value from a hardware source. It returns a valid value, allowing consuming code to be runnable. The function ignores the input parameter source which is common for a stub.

function ReadThermometer(Source source) return 28 end function

Distributed computing

In distributed computing, stub is like a mock object , simulates existing code, such as a procedure on a remote machine. Such stubs can be useful in porting.

In RMI nomenclature, a stub on the client-side communicates with a skeleton on the server-side.

Windows/MS-DOS

In Windows and MS-DOS, stub is like a shim , small interface code left in conventional memory by self-relocating resident drivers which move most of themselves into upper memory, the high memory area, expanded or extended memory as well as similar stubs to allow the relocated code to communicate with real-mode DOS in conjunction with DOS extenders (like DPMI, DPMS, CLOAKING or NIOS).
