RTT::Parser

Parser Class Reference

#include <rtt/scripting/Parser.hpp>

Detailed Description

This class is the public interface to the Orocos Program Parser Framework. It parsers Orocos program scripts, Orocos State Contexts and allows to parse a text Command, Condition or Expression to the respective objects.

See also:: ProgramLoader. Use the ProgramLoader for a more user friendly loading of scripts into TaskContexts.

Member Function Documentation

Parser::ParsedFunctions parseFunction	(	const std::string &	s,
		TaskContext *	c,
		const std::string &	filename = `"stream"`
	)

Reads out the string, parses it, and returns a new FunctionGraph.

Exceptions:

parse_exception

Throws exceptions of type parse_exception.

Definition at line 53 of file Parser.cpp.

References ProgramGraphParser::parseFunction().

Parser::ParsedPrograms parseProgram	(	const std::string &	s,
		TaskContext *	c,
		const std::string &	filename = `"stream"`
	)

Reads out the string, parses it, and returns a new ProgramGraph.

Exceptions:

parse_exception

Throws exceptions of type parse_exception.

References ProgramGraphParser::parse().

Parser::ParsedStateMachines parseStateMachine	(	const std::string &	s,
		TaskContext *	c,
		const std::string &	filename = `"stream"`
	)

Reads out the string, parses it, and returns a new ParsedStateMachine.

Exceptions:

file_parse_exception

Throws exceptions of type file_parse_exception.

ConditionInterface * parseCondition	(	const std::string &	s,
		TaskContext *	tc
	)

Parses the string as a condition, and returns a new ConditionInterface. Will throw parse_exception on failure. Use ext to get the data from the components.

Exceptions:

parse_exception
