Public Member Functions | |
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. More... | |
base::DataSourceBase::shared_ptr | parseExpression (const std::string &s, TaskContext *) |
Parses the expression in s. More... | |
ParsedFunctions | parseFunction (const std::string &s, TaskContext *, const std::string &filename="stream") |
Reads out the string, parses it, and returns a new FunctionGraph. More... | |
ParsedPrograms | parseProgram (const std::string &s, TaskContext *, const std::string &filename="stream") |
Reads out the string, parses it, and returns a new ProgramGraph. More... | |
Parser (ExecutionEngine *caller=0) | |
ParsedStateMachines | parseStateMachine (const std::string &s, TaskContext *, const std::string &filename="stream") |
Reads out the string, parses it, and returns a new ParsedStateMachine. More... | |
base::DataSourceBase::shared_ptr | parseValueChange (const std::string &s, TaskContext *) |
Parses a change of a value in s. More... | |
base::DataSourceBase::shared_ptr | parseValueStatement (const std::string &s, TaskContext *) |
Parses a whole value manipulation/creation statement. Requires the set/var/const etc prefixes. More... | |

RTT::Parser::Parser | ( | ExecutionEngine * | caller = 0 | ) |
Create a parser and allow to explicitly specify which TaskContext's ExecutionEngine is calling it. This allows to generate the correct asynchonous method invocation code in case caller and parser are not identical.
