Detailed Description

Float substep argument.

Constructor & Destructor Documentation

__init__()

def python.trfArgClasses.argSubstepFloat.__init__	(		self,
			value = None,
			runarg = None,
			name = None,
			defaultSubstep = True,
			separator = None
	)

argSubstep constructor

Parameters

defaultSubstep

Default substep to use when no specific substep has been given - this should be set to first for arguments that apply, by default, to the first executor in the chain (e.g., maxEvents)

Reimplemented from python.trfArgClasses.argSubstep.

_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

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!
