Constructor & Destructor Documentation

RTT::Parser::Parser ( TaskContext caller = 0)

Create a parser and allow to explicitly specify which TaskContext is calling it. This allows to generate the correct asynchonous method invocation code in case caller and parser are not identical.

Member Function Documentation

ConditionInterface * RTT::Parser::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

Definition at line 134 of file Parser.cpp.

Parses the expression in s.

Returns:
A base::DataSourceBase which contains the expression.
Exceptions:
parse_exceptionThrows exceptions of type parse_exception.

Definition at line 163 of file Parser.cpp.

Parser::ParsedFunctions RTT::Parser::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_exceptionThrows exceptions of type parse_exception.

Definition at line 84 of file Parser.cpp.

Parser::ParsedPrograms RTT::Parser::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_exceptionThrows exceptions of type parse_exception.

Definition at line 96 of file Parser.cpp.

Parser::ParsedStateMachines RTT::Parser::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_exceptionThrows exceptions of type file_parse_exception.

Definition at line 110 of file Parser.cpp.

Parses a change of a value in s.

Returns:
A base::DataSourceBase which contains the command to change the value.
Exceptions:
parse_exceptionThrows exceptions of type parse_exception.

Definition at line 194 of file Parser.cpp.

Parses a whole value manipulation/creation statement. Requires the set/var/const etc prefixes.

Returns:
A base::DataSourceBase which contains the command to change the value.
Exceptions:
parse_exceptionThrows exceptions of type parse_exception.

Definition at line 200 of file Parser.cpp.

void RTT::Parser::runScript ( std::string const &  code,
TaskContext mowner,
ScriptingService service,
std::string const &  filename 
)

Runs all statements in code.

Parameters:
codeA list of scripting statements and definitions
mownerThe task in which the code must be interpreted
filenameAn informational description of the source of code.
Exceptions:
parse_exceptionand its derivatives.
