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..

) |
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.

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..

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.

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'
