Detailed Description

This class is the base class for the service classes.

See also:

LLIOPipe

The services map a string to a chain factory with a known interface at the front of the chain. So, to activate a service, call activate() with the name of the service needed which will call the associated factory, and return a pointer to the known interface. NOTE: If you are implementing a service factory, it is vitally important that the service pipe is at the front of the chain.
