_parseStringAsSubstep()

def python.trfArgClasses.argSubstep._parseStringAsSubstep (   self,   string  )

privateinherited

Parse a string for substep:value format.

If the string matches the substep specifier regexp then we return the two parts; if not then the substep is returned as self._defaultSubstep, with the entire string passed back as the value

Parameters

string

The string which should be parsed

For strings passed to the setter we expect the format to be substep:{in/out}{+/-}DATATYPE or to be a steering alias, which is then expanded to the more complex format. This is then cast into a dictionary of tuples {substep: [('in/out', '+/-', DATATYPE), ...], ...}

Note

We have a default of None here, but all derived classes should definitely have their own value setter and translate this value to something sensible for their underlying value type. N.B. As most argument classes use this default constructor it must call the @value .setter function!
