Detailed Description

An action which calls a FunctionFraph for execution in a ExecutionEngine.

Script functions are always executed in the thread of the component.

It is an DataSource such that it can be executed by program scripts.

inline

Create a Command to send a function to a ExecutionEngine.

Parameters

init_com	The command to execute before sending the function into the processor, in order to initialise it.
foo	The function to run in the processor.
p	The target processor which will run the function.
v	Implementation specific parameter to support copy/clone semantics.

inlinevirtual

When copying an Orocos program, we want identical internal::DataSource's to be mapped to identical DataSources, in order for the program to work correctly.

This is different from the clone function, where we simply want a new Action that can replace the old one directly.

This function takes a map that maps the old internal::DataSource's onto their new replacements. This way, it is possible to check before cloning a internal::DataSource, whether it has already been copied, and if so, reuse the existing copy.

To keep old source working, the standard implementation of this function simply calls the clone function. If your ActionInterface uses a internal::DataSource, it is important that you reimplement this function correctly though.

Reimplemented from RTT::base::ActionInterface.

virtual bool RTT::scripting::CallFunction::execute ( )

inlinevirtual

Execute the functionality of this action.

Returns: true if the action was accepted, false otherwise

Implements RTT::base::ActionInterface.

Definition at line 108 of file CallFunction.hpp.

virtual void RTT::scripting::CallFunction::readArguments ( )

inlinevirtual

This is invoked some time before execute() at a time when the action may read its function arguments.

Implements RTT::base::ActionInterface.

Definition at line 140 of file CallFunction.hpp.

virtual void RTT::scripting::CallFunction::reset ( )

inlinevirtual

Reset this action.

Must be used after execute() failed.

Reimplemented from RTT::base::ActionInterface.

Definition at line 130 of file CallFunction.hpp.

References RTT::ExecutionEngine::removeFunction().

virtual bool RTT::scripting::CallFunction::valid ( ) const

inlinevirtual

Inspect if this action was executed and valid.

This method may not be called before execute(). The default implementation returns always true, i.e. after execute(), it was executed. Override this method if it has more complex state semantics.

Reimplemented from RTT::base::ActionInterface.
