#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.
Add a new ServiceRequester to this TaskContext.
- Parameters:
-
obj This object becomes owned by this TaskContext.
- Returns:
- true if it could be added, false if such service requester already exists.
Definition at line 122 of file ServiceRequester.cpp.
| void RTT::ServiceRequester::clear | ( | ) | [virtual] |
Remove all operation callers from this service requester.
Definition at line 184 of file ServiceRequester.cpp.
| bool RTT::ServiceRequester::connectTo | ( | Service::shared_ptr | sp | ) | [virtual] |
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.

| void RTT::ServiceRequester::disconnect | ( | ) | [virtual] |
Disconnects all methods from their implementation.

| std::vector< std::string > RTT::ServiceRequester::getOperationCallerNames | ( | ) | const |
Definition at line 74 of file ServiceRequester.cpp.
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.

| const std::string& RTT::ServiceRequester::getRequestName | ( | ) | const [inline] |
Definition at line 98 of file ServiceRequester.hpp.
| TaskContext* RTT::ServiceRequester::getServiceOwner | ( | ) | const [inline] |
The owner is the top-level TaskContext owning this service (indirectly).
Definition at line 106 of file ServiceRequester.hpp.
| bool RTT::ServiceRequester::ready | ( | ) | const [virtual] |
Returns true when all methods were resolved.
- Returns:

| bool RTT::ServiceRequester::requiresService | ( | const std::string & | service_name | ) | [inline] |
Query if this service requires certain sub-services.
- Parameters:
-
service_name

| void RTT::ServiceRequester::setOwner | ( | TaskContext * | new_owner | ) |
Sets the owning TaskContext that is considered as the caller of requested operations.
