template<class T >

bool RTT::ConfigurationInterface::addAttribute	(	const std::string &	name,
		T &	attr
	)		`[inline, inherited]`

Adds a variable of any type as read/write attribute to the configuration interface.

An Alias is created which causes contents of the attr variable always to be in sync with the contents of the attribute object in the interface.

Parameters:

name	The name of this attribute
attr	The variable that will be aliased.

Definition at line 101 of file ConfigurationInterface.hpp.

template<class T >

bool RTT::Service::setOperationThread	(	std::string const &	name,
		ExecutionThread	et

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:

name	The name of the operation to modify. For example, "start".
et	The 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.
