Invocation adapters form the connection between a caller (of a method) and an ORB similar to the way in which object adapters establish a connection between an ORB and object implementations. Invocation adapters in a microkernel ORB are separate services from the ORB core. Similar to object adapters, they conceal different types of callers from the ORB, thereby making it possible for the ORB kernel to be small and flexible.

This chapter will first introduce some of the fundamental concepts concerning invocation adapters. It will then look at two special adapters—the Dynamic Invocation Interface (DII) and the Static Invocation Interface (SII)—and how they are implemented in MICO.
