Detailed Description

template<class SignatureT>
class RTT::OperationCaller< SignatureT >

A OperationCaller serves as a placeholder (aka 'proxy') for a remote Operation. If you want to call an operation, you need this class to do it.

The OperationCaller has the exact same signature template argument as the Operation it wishes to call.

OwnThread operations need the caller's ExecutionEngine to be able to inform it of completion . In case the caller has no ExecutionEngine, the GlobalEngine is used instead, and the GlobalEngine will block until the call completes.

Constructor & Destructor Documentation

template<class SignatureT>
RTT::OperationCaller< SignatureT >::OperationCaller ( )
inline

Create an empty OperationCaller object. Use assignment to initialise it.

Definition at line 103 of file OperationCaller.hpp.

template<class SignatureT>
RTT::OperationCaller< SignatureT >::OperationCaller ( std::string  name,
ExecutionEngine caller = 0 
)
inline

Create an OperationCaller object with a name and optional caller.

Parameters
nameThe name of the operation that will be called.
nameThe ExecutionEngine of the TaskContext calling the operation.

Definition at line 112 of file OperationCaller.hpp.

template<class SignatureT>
RTT::OperationCaller< SignatureT >::OperationCaller ( const OperationCaller< SignatureT > &  m)
inline

OperationCaller objects may be copied. A deep copy is made of the implementation object such that using this object does not interfere when using the original, m.

Parameters
mthe original

Definition at line 123 of file OperationCaller.hpp.

template<class SignatureT>
RTT::OperationCaller< SignatureT >::OperationCaller ( boost::shared_ptr< base::DisposableInterface implementation,
ExecutionEngine caller = 0 
)
inline

Initialise a nameless OperationCaller object from a local Operation.

Parameters
implementationThe implementation of the operation which is to be used by the OperationCaller object. This object will be cloned such that the method uses its own implementation.
callerThe ExecutionEngine which will be used to call us back in case of asynchronous communication. If zero, the global Engine is used.

Definition at line 159 of file OperationCaller.hpp.

template<class SignatureT>
RTT::OperationCaller< SignatureT >::OperationCaller ( OperationInterfacePart part,
ExecutionEngine caller = 0 
)
inline

Initialise a nameless OperationCaller object from an operation factory.

Parameters
partThe OperationInterfacePart which is used by the OperationCaller object to get the implementation.
callerThe ExecutionEngine which will be used to call us back in case of asynchronous communication. If zero, the global Engine is used.

Definition at line 180 of file OperationCaller.hpp.

template<class SignatureT>
RTT::OperationCaller< SignatureT >::OperationCaller ( const std::string &  name,
ServicePtr  service,
ExecutionEngine caller = 0 
)
inline

Initialise a named OperationCaller object from a Service.

Parameters
nameThe name of the operation to look for.
serviceThe Service where the operation will be looked up.
callerThe ExecutionEngine which will be used to call us back in case of asynchronous communication. If zero, the global Engine is used.

Definition at line 199 of file OperationCaller.hpp.

template<class SignatureT>
RTT::OperationCaller< SignatureT >::~OperationCaller ( )
inline

Clean up the OperationCaller object.

Definition at line 317 of file OperationCaller.hpp.

Member Function Documentation

template<class SignatureT>
void RTT::OperationCaller< SignatureT >::disconnect ( )
inlinevirtual

Disconnects this caller from the operation it was connected to. If this OperationCaller had a name, the name is still kept.

Postcondition
this->ready() == false

Implements RTT::base::OperationCallerBaseInvoker.

Definition at line 373 of file OperationCaller.hpp.

template<class SignatureT>
std::string const& RTT::OperationCaller< SignatureT >::getName ( ) const
inlinevirtual

Get the name of this OperationCaller.

Implements RTT::base::OperationCallerBaseInvoker.

Definition at line 333 of file OperationCaller.hpp.

template<class SignatureT>
const OperationCallerBasePtr RTT::OperationCaller< SignatureT >::getOperationCallerImpl ( ) const
inline

Returns the internal implementation of the OperationCaller object.

Definition at line 356 of file OperationCaller.hpp.

template<class SignatureT>
OperationCaller& RTT::OperationCaller< SignatureT >::operator= ( const OperationCaller< SignatureT > &  m)
inline

OperationCaller objects may be assigned. A deep copy is made of the implementation object such that using this object does not interfere when using the original, m.

Parameters
mthe original
Returns
*this

Definition at line 137 of file OperationCaller.hpp.

template<class SignatureT>
OperationCaller& RTT::OperationCaller< SignatureT >::operator= ( boost::shared_ptr< base::DisposableInterface implementation)
inline

OperationCaller objects may be assigned to an implementation. This variant is used when a local implementation is available.

Parameters
implementationthe implementation.
Returns
*this

Definition at line 218 of file OperationCaller.hpp.

template<class SignatureT>
OperationCaller& RTT::OperationCaller< SignatureT >::operator= ( OperationInterfacePart part)
inline

OperationCaller objects may be assigned to a part responsible for production of an implementation. This variant is used when a only a remote implementation is available.

Parameters
partThe part used by the OperationCaller to produce an implementation.
Returns
*this

Definition at line 236 of file OperationCaller.hpp.

template<class SignatureT>
OperationCaller& RTT::OperationCaller< SignatureT >::operator= ( ServicePtr  service)
inline

Named OperationCaller objects may be looked up in a Service.

Parameters
serviceThe Service where the operation will be looked up.
Returns
*this

Definition at line 256 of file OperationCaller.hpp.

template<class SignatureT>
bool RTT::OperationCaller< SignatureT >::ready ( ) const
inlinevirtual

Check if this OperationCaller is ready for execution.

Returns
true if so.

Implements RTT::base::OperationCallerBaseInvoker.

Definition at line 326 of file OperationCaller.hpp.

template<class SignatureT>
void RTT::OperationCaller< SignatureT >::setCaller ( ExecutionEngine caller)
inlinevirtual

Sets the caller of this method after the implementation was set.

Parameters
caller

Implements RTT::base::OperationCallerBaseInvoker.

Definition at line 367 of file OperationCaller.hpp.

template<class SignatureT>
bool RTT::OperationCaller< SignatureT >::setImplementation ( boost::shared_ptr< base::DisposableInterface impl,
ExecutionEngine caller = 0 
)
inlinevirtual

Sets a new implementation for this method.

Parameters
implAn implementation object that can be upcast to the OperationCallerBase class type of this method.
callerThe engine of the calling TaskContext.
Returns
true if the impl could be upcast to a matching OperationCallerBase type, false otherwise.

Implements RTT::base::OperationCallerBaseInvoker.

Definition at line 335 of file OperationCaller.hpp.

template<class SignatureT>
bool RTT::OperationCaller< SignatureT >::setImplementationPart ( OperationInterfacePart orp,
ExecutionEngine caller = 0 
)
inlinevirtual

Sets a new implementation for this method by using a service part.

Parameters
orpA part obtained from a service's OperationInterface.
callerThe engine of the calling TaskContext.
Returns
true if the part could produce the correct OperationCallerBase type, false otherwise.
