Detailed Description

This class represents a function. It has much in common with a program but is only used for storing a Graph.

Constructor & Destructor Documentation

RTT::FunctionGraph::FunctionGraph	(	const std::string &	name,
		bool	unload_on_stop
	)

Create a FunctionGraph with a given name.

Parameters:

name The name of this script.

unload_on_stop Set to true to force an unload when the script stops or an error is encountered. The unload is forced by returning false in execute(), as defined in the ExecutableInterface. This flag should only be set to true for scripts that don't have a service associated (see setProgramService() ), since the service is destroyed when the function is unloaded. You can override this behavior after construction by using setUnloadOnStop().

Member Function Documentation

void RTT::scripting::FunctionGraph::addArgument ( base::AttributeBase * a ) [inline]

Definition at line 248 of file FunctionGraph.hpp.

void RTT::FunctionGraph::clearArguments ( )

Clear the arguments vector and release all base::AttributeBase resources.

Definition at line 459 of file FunctionGraph.cpp.

FunctionGraph * RTT::FunctionGraph::clone ( ) const [virtual]

Implements RTT::scripting::ProgramInterface.

Definition at line 432 of file FunctionGraph.cpp.

FunctionGraph * RTT::FunctionGraph::copy ( std::map< const base::DataSourceBase *, base::DataSourceBase * > & replacementdss ) const [virtual]

Clone this Program. This will produce a completely new instance, that has nothing in common with this one. It takes care to properly map identical DataSources to identical DataSources.

Parameters:

alreadyMappedData A map of some DataSources used in this program to new DataSources that should replace them in the new Program. This is provided, because in some cases the outside world also keeps references to datasources used somewhere in this programgraph. It is then important that when this Program is copied, the outside world has a way to get a reference to the corresponding datasources in the new program. We do this by allowing it to map some datasources itself, and simply provide us a list of its mappings.

void RTT::FunctionGraph::debugPrintout ( ) const

Definition at line 437 of file FunctionGraph.cpp.

bool RTT::FunctionGraph::execute ( ) [virtual]

Execute as much actions until the program needs to wait on a condition to become true. When paused, only execute one action.

Returns:: false if a program error occured.

Vertex RTT::scripting::FunctionGraph::exitNode ( ) const [inline]

Definition at line 222 of file FunctionGraph.hpp.

void RTT::FunctionGraph::finish ( )

To be called after a function is constructed.

Definition at line 94 of file FunctionGraph.cpp.

std::vector<base::AttributeBase*> RTT::scripting::FunctionGraph::getArguments ( ) const [inline, virtual]

Return an ordered list of this funcion's arguments.

int RTT::FunctionGraph::getLineNumber ( ) const [virtual]

Return the current 'line number' of the program.

Implements RTT::scripting::ProgramInterface.

const std::string & RTT::FunctionGraph::getName ( ) const [virtual]

Programs can be refered to by name.

Implements RTT::scripting::ProgramInterface.

base::AttributeBase* RTT::scripting::FunctionGraph::getResult ( ) const [inline, virtual]

Get the return value of this program.

Implements RTT::scripting::ProgramInterface.

Definition at line 244 of file FunctionGraph.hpp.

std::string RTT::FunctionGraph::getText ( ) const [virtual]

Return the program text to which getLineNumber() refers.

Implements RTT::scripting::ProgramInterface.

Definition at line 368 of file FunctionGraph.cpp.

void RTT::FunctionGraph::loading ( ) [virtual]

Informs this object that it got loaded in an ExecutionEngine. Called by load() after the engine pointer is set.

Reimplemented from RTT::base::ExecutableInterface.

Definition at line 136 of file FunctionGraph.cpp.

virtual bool RTT::scripting::FunctionGraph::needsStart ( ) const [inline, virtual]

Returns true if a start() is necessary when this function is loaded with ExecutionEngine::runFunction(). Functions that unload_on_stop == true don't need to be started since they will start themselves when loaded in the EE.

Pause or start-and-pause the execution of this program.
