GlobalInterface
An object that can be accessed as a module global.
Examples:
First, we need to set up a stub name resolver:
>>> d = {'x': 1, 'y': 42, 'z': 'zope'} >>> class fakeresolver(dict): ... def resolve(self, n): ... return self[n]
>>> fake = fakeresolver(d)
>>> g = GlobalObject(value_type=schema.Int()) >>> gg = g.bind(fake) >>> gg.fromUnicode("x") 1 >>> gg.fromUnicode(" x \n ") 1 >>> gg.fromUnicode("y") 42 >>> gg.fromUnicode("z") Traceback (most recent call last): ... WrongType: ('zope', (<type 'int'>, <type 'long'>))
>>> g = GlobalObject(constraint=lambda x: x%2 == 0) >>> gg = g.bind(fake) >>> gg.fromUnicode("x") Traceback (most recent call last): ... ConstraintNotSatisfied: 1 >>> gg.fromUnicode("y") 42 >>> g = GlobalObject() >>> gg = g.bind(fake) >>> gg.fromUnicode('*') >>>
