Constructor & Destructor Documentation

RTT::ScriptParser::ScriptParser	(	iter_t &	positer,
		TaskContext *	tc,
		ExecutionEngine *	caller
	)

Initialize with an initial position, the TaskContext in which context to parse the scripts and the TaskContext that will call the parse() functions.

void RTT::ScriptParser::parse	(	iter_t &	begin,
		iter_t	end
	)

Parses and executes the script from begin to end. The script must be complete and well formed.

Exceptions

parse_exception

or one of its variants in case of wrong input

Definition at line 206 of file ScriptParser.cpp.

base::DataSourceBase::shared_ptr RTT::scripting::ScriptParser::parseExcerpt	(	iter_t &	begin,
		iter_t	end
	)

Parses and executes a (possibly) incomplete script.

Returns

a valid datasource which contains the result of the last statement parsed. It does not need to be evaluate()'ed anymore to read its contents. In case the input is incomplete, a null data source is returned.

Exceptions

parse_exception

or one of its variants in case of wrong input
