Detailed Description

Argument class for substep lists, suitable for preExec/postExec.

substep is followed by a ':' then the python fragments. The substep is validated and set as the key in a dictionary with the value being the python following the ':'.

• If no substep (e.g. r2a) is specified, it will be parsed for 'all'.

  Note

  substep can be either the subspet property of an executor or the executor's name. Thus r2a:something is the same as RAWtoALL:something.

__init__()

def python.trfArgClasses.argSubstepList.__init__	(		self,
			value = None,
			runarg = True,
			name = None,
			defaultSubstep = 'all',
			splitter = None,
			separator = ':'
	)

argSubstepList constructor

Parameters

splitter

Character used to split the string into multiple list elements

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!
