#include <ServiceRequester.hpp>
Detailed Description
An object that expresses you wish to use a service. The ServiceRequester is symmetrical to the Service. Where a Service registers operations that a component can execute ('provides'), the ServiceRequester registers the methods that a caller wishes to call ('requires'). One method in a ServiceRequester maps to one operation in a Service.
Typical use is to inherit from ServiceRequester and add named OperationCaller objects to it using addOperationCaller.

Member Function Documentation
Definition at line 63 of file ServiceRequester.cpp.
Connects this service's methods to the operations provided by op. This method tries to match as many as possible method-operation pairs.
You may call this function with different instances of sp to 'resolve' missing functions, only the non-connected methods will be further filled in.
- Parameters:
-
sp An interface-compatible Service.
- Returns:
- true if all methods of that are required are provided, false if not all methods could yet be matched.

Returns the service we're referencing. In case you used connectTo to more than one service, this returns the service which was used when connectTo first returned true.
