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.

	)

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

Exceptions:

parse_exception

Throws exceptions of type parse_exception.

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.
