Parameters:
nameThe name of this attribute
cnstThe variable that will be aliased.

Definition at line 135 of file ConfigurationInterface.hpp.

bool RTT::Service::setOperationThread ( std::string const &  name,
ExecutionThread  et 
) [inherited]

Sets the thread of execution of a previously added operation.

Only the component itself should modify this property. Don't call this function from outside the component, it has unspecified behaviour when not called from within one of the member functions or a service of the current component.

This function is typically used to change the ExecutionThread of the standard component hooks such as startHook(), configureHook() etc. which all have the ClientThread policy by default.

Parameters:
nameThe name of the operation to modify. For example, "start".
etThe ExecutionThread type in which the function of the operation will be executed, being OwnThread or ClientThread.
Returns:
true if name was a local, present operation, false otherwise.

bool RTT::DataFlowInterface::setPortDescription ( const std::string &  name,
const std::string  description 
) [inherited]

Sets the description for the service of an added port.

It's prefered to use getPort(name)->doc(description) instead of this method, since this function only updates the documentation of the service representing this port, and not the documentation stored in the port.

Parameters:
nameThe port name
descriptionThe new description for this port's service
Returns:
true if the port was found and the description was set, false otherwise.
