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

ParsedFunctions parseFunction	(	const std::string &	s,
		TaskContext *	,
		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.

ParsedPrograms parseProgram	(	const std::string &	s,
		TaskContext *	,
		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.

ParsedStateMachines parseStateMachine	(	const std::string &	s,
		TaskContext *	,
		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 *
	)

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

std::pair<CommandInterface*,ConditionInterface*> parseCommand	(	const std::string &	s,
		TaskContext *	t,
		bool	dispatch
	)

Parses the command in s.

Exceptions:

parse_exception

Throws exceptions of type parse_exception.

DataSourceBase::shared_ptr parseExpression	(	const std::string &	s,
		TaskContext *
	)

Parses the expression in s.

Returns:

A DataSourceBase which contains the expression.

Exceptions:

parse_exception

Throws exceptions of type parse_exception.

DataSourceBase::shared_ptr parseValueChange	(	const std::string &	s,
		TaskContext *
	)

Parses a change of a value in s.

Returns:

A DataSourceBase which contains the command to change the value.

Exceptions:

parse_exception

Throws exceptions of type parse_exception.
