Method Details

implementedBy(self, cls)

Test whether the specification is implemented by a class or factory. Raise TypeError if argument is neither a class nor a callable.

isOrExtends(self, interface)

Is the interface the same as or extend the given interface

Examples: 
 >>> from gnue.navigator.external.zope.interface import Interface
 >>> from gnue.navigator.external.zope.interface.declarations import Declaration
 >>> class I1(Interface): pass
 ...
 >>> class I2(I1): pass
 ...
 >>> class I3(Interface): pass
 ...
 >>> class I4(I3): pass
 ...
 >>> spec = Declaration()
 >>> int(spec.extends(Interface))
 0
 >>> spec = Declaration(I2)
 >>> int(spec.extends(Interface))
 1
 >>> int(spec.extends(I1))
 1
 >>> int(spec.extends(I2))
 1
 >>> int(spec.extends(I3))
 0
 >>> int(spec.extends(I4))
 0

providedBy(self, ob)

Is the interface implemented by an object 
>>> from gnue.navigator.external.zope.interface import *
>>> class I1(Interface):
...     pass
>>> class C(object):
...     implements(I1)
>>> c = C()
>>> class X(object):
...     pass
>>> x = X()
>>> I1.providedBy(x)
False

>>> I1.providedBy(C)
False

>>> I1.providedBy(c)
True

>>> directlyProvides(x, I1)
>>> I1.providedBy(x)
True

>>> directlyProvides(C, I1)
>>> I1.providedBy(C)
True
