Function Details

_flatten(ob, result)

mergeOrderings(orderings, seen=None)

Merge multiple orderings so that within-ordering order is preserved

Orderings are constrained in such a way that if an object appears in two or more orderings, then the suffix that begins with the object must be in both orderings.

For example:

>>> _mergeOrderings([
... ['x', 'y', 'z'],
... ['q', 'z'],
... [1, 3, 5],
... ['z']
... ])
['x', 'y', 'q', 1, 3, 5, 'z']

ro(object)

Compute a "resolution order" for an object

Module gnue.navigator.external.zope.interface.ro
