bool RTT::MarshallingService::readServiceProperties	(	const std::string &	filename,
		const std::string &	servicename
	)		const

Read the property file and 'refresh' all the properties of a Service.

There may be more properties in the file than properties in the Service, but all properties of the Service must be present in filename. In case a type mismatch occurs, this method will fail and update no properties.

Parameters

filename	The file to read from.
servicename	Service to use

Returns: true on success, false on error, consult Logger output for messages.

bool RTT::MarshallingService::readServiceProperty	(	const std::string &	name,
		const std::string &	filename,
		const std::string &	servicename
	)

Read a single property from a file.

The name may be a 'path' like location of a Property in the hierarchy.

Parameters

name	The name of the property in the file. For example "MyProp" for a top-level property or "Settings.XML.Editor" to specify a dot-separated 'path' to the property 'Editor'.
filename	The name of the file in which to lookup name.
servicename	Service to use

void OperationInterface::remove ( const std::string & name )

name	The name of the operation

void RTT::DataFlowInterface::removeLocalPort ( const std::string & name )

inherited

Remove a locally added Port from this interface.

This will remove all connections and callbacks assosiated with this port.

Parameters

port	The port to remove.

Note: this function will not check if a service with the same name as name exists, and will not remove it. So use removePort() in case you want to get rid of the service as well.

void RTT::DataFlowInterface::removePort ( const std::string & name )

inherited

Remove a Port from this interface.

This will remove all services, connections and callbacks assosiated with this port.

Parameters

port	The port to remove.

Note: Since services are refcounted, removePort may effectively delete the this object in case no Service::shared_ptr exists to this DataFlowInterface. In order to prevent such cleanup, create a Service::shared_ptr to this object before calling removePort().

bool RTT::ConfigurationInterface::removeProperty ( base::PropertyBase & p )

Returns: false if no such property exists.

void RTT::Service::removeService ( std::string const & service_name )

virtualinherited

Remove a previously added sub-service, potentially freeing it (and this) from memory.

Parameters

service_name the name of the service to remove.

Note: Since service_name holds a reference to this Service, removeService may also delete this Service. In order to protect against such deletion, take a Service::shared_ptr to this before calling removeService.

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

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.

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

name	The port name
description	The new description for this port's service

Returns: true if the port was found and the description was set, false otherwise.

bool RTT::MarshallingService::updateFile ( const std::string & filename ) const

Write the property file with the properties of a TaskContext, which are already present in filename.

No new entries are created in the file, only existing ones are updated. The file is first read in, the resulting tree is updated with the task's properties, and then written to disk again.

Parameters

filename The file to read from and write to.

Returns: true on success, false on error, consult Logger output for messages.
