A CheckedPSet is a PSet which allows specifying type and invariant checks. >>> class Positives(CheckedPSet): ... __type__ = (int, float) ... __invariant__ = lambda n: (n >= 0, 'Negative') ... >>> Positives([1, 2, 3]) Positives([1, 2, 3])

| def evolver | ( | self | ) |
Create a new evolver for this pset. For a discussion on evolvers in general see the documentation for the pvector evolver. Create the evolver and perform various mutating updates to it: >>> s1 = s(1, 2, 3) >>> e = s1.evolver() >>> _ = e.add(4) >>> len(e) 4 >>> _ = e.remove(1) The underlying pset remains the same: >>> s1 pset([1, 2, 3]) The changes are kept in the evolver. An updated pmap can be created using the persistent() function on the evolver. >>> s2 = e.persistent() >>> s2 pset([2, 3, 4]) The new pset will share data with the original pset in the same way that would have been done if only using operations on the pset.
