Detailed Description

This class is responsible for parsing constant definitions, variable definitions, variable change instructions, and alias definitions.. It stores these in the ValueParser in the ParseContext, and parses values using ExpressionParser..

Todo:: The ValueChangeParser.cxx implementation needs refactoring.

Constructor & Destructor Documentation

RTT::ValueChangeParser::ValueChangeParser	(	TaskContext *	tc,
		CommonParser &	cp,
		Service::shared_ptr	storage,
		ExecutionEngine *	caller
	)

Create a ValueChangeParser which operates and stores values in a task. Use definedvalues() to get the values added to tc, use store() to store the added values in another task context as well. After reset(), tc will be cleared of all the stored values. tc is thus used as a temporary storage container. If you want the new added values in a different storage container, use the storage argument. Defaults to tc->provides() if set to null.

Member Function Documentation

rule_t & RTT::ValueChangeParser::aliasDefinitionParser ( )

The parser that parses alias definitions. This does not work via an assignment, and it is not necessary to check assignCommand() after this..

Definition at line 367 of file ValueChangeParser.cpp.

std::vector<std::string> RTT::scripting::ValueChangeParser::allDefinedNames ( ) [inline]

Definition at line 193 of file ValueChangeParser.hpp.

base::ActionInterface* RTT::scripting::ValueChangeParser::assignCommand ( ) [inline]

This base::ActionInterface holds the command assigning a value to a variable that should be included in the program. After a constant definition, variable definition or variable assignment is parsed, you should check it, and include it in your program if it is non-zero.

Definition at line 157 of file ValueChangeParser.hpp.

std::vector<base::ActionInterface*> RTT::scripting::ValueChangeParser::assignCommands ( ) [inline]

Definition at line 164 of file ValueChangeParser.hpp.

rule_t & RTT::ValueChangeParser::bareDefinitionParser ( )

The parser that parses a bare variable definition. These do not get initialised where they are defined, so it is not necessary to check assignCommand() after this...

Definition at line 382 of file ValueChangeParser.cpp.

void RTT::ValueChangeParser::cleanup ( ) [private]

Delete temporary variables before throwing an exception.

Definition at line 328 of file ValueChangeParser.cpp.

void RTT::ValueChangeParser::clear ( )

Clear assignCommands(), definedValues() and definedNames(). Does not delete any variables or commands.

Definition at line 333 of file ValueChangeParser.cpp.

rule_t & RTT::ValueChangeParser::constantDefinitionParser ( )

the parser that parses definitions of constants. Do not forget to check assignCommand after a constant definition is parsed..

Definition at line 362 of file ValueChangeParser.cpp.

std::vector<std::string> RTT::scripting::ValueChangeParser::definedNames ( ) [inline]

Definition at line 188 of file ValueChangeParser.hpp.

std::vector<base::AttributeBase*> RTT::scripting::ValueChangeParser::definedValues ( ) [inline]

Definition at line 176 of file ValueChangeParser.hpp.

std::string RTT::scripting::ValueChangeParser::lastDefinedName ( ) [inline]

Definition at line 181 of file ValueChangeParser.hpp.

base::AttributeBase* RTT::scripting::ValueChangeParser::lastDefinedValue ( ) [inline]

Definition at line 169 of file ValueChangeParser.hpp.

void RTT::ValueChangeParser::load ( Service::shared_ptr source )

Loads all defined names from a service. Just like store(), but works the other way around and allows you to pre-defined some variables. This function removes all these variables from 'source'

Definition at line 313 of file ValueChangeParser.cpp.

rule_t & RTT::ValueChangeParser::paramDefinitionParser ( )

The parser that parses state context parameter definitions. These do not get initialised where they are defined, so it is not necessary to check assignCommand() after this...

Definition at line 377 of file ValueChangeParser.cpp.

rule_t & RTT::ValueChangeParser::parser ( )

Returns the full parser, as it is used most. The individual sub-parsers are below.
