Constructor & Destructor Documentation

__init__()

def GaudiHive.precedence.RndBiasedBooleanValue.__init__	(		self,
			pattern,
			seed = None
	)

Keyword arguments:
pattern -- either a dictionary describing proportion of True and False (e.g., {True:5,False:15}), or
   a list/tuple containing a pattern to be used as-is (e.g., [False,True,True,False])
seed -- an int, long or other hashable object to initialize random number generator (passed to random.shuffle as-is)
