Interface declaration

Declarations are used to express the interfaces implemented by classes or provided by objects.

Method Summary
Inherited from InterfaceClass
	`__contains__(self, name)`
	`__iter__(self)`
	`extends(self, interface, strict)` Does the specification extend the given interface?
	`get(self, name, default)` Query for an attribute description
	`isOrExtends(self, interface)` Is the interface the same as or extend the given interface
	`weakref(self, callback)`

Class Variable Details

Type:: str
Value:: '''Create an interface specification with some interfaces added The argument can be an interface or an interface specifications. The interface or interfaces given in a specification are added to the interface specification. Adding an interface that is already in the specification does not raise an error. Doing so has no effect. ...

Type:: str
Value:: '''Return a true value of the interface specification is non-empty '''

Type:: tuple
Value:: (<InterfaceClass zope.interface.interfaces.IDeclaration>, <InterfaceClass zope.interface.interfaces.ISpecification>, <InterfaceClass zope.interface.Interface>)

Type:: str
Value:: '''Create an interface specification with some interfaces excluded The argument can be an interface or an interface specifications. The interface or interfaces given in a specification are subtracted from the interface specification. Removing an interface that is not in the specification does not raise an error. Doing so has no effect. ...

Type:: str
Value:: '''Return an iterator of all included and extended interfaces An iterator is returned for all interfaces either included in or extended by interfaces included in the specifications without duplicates. The interfaces are in "interface resolution order". The interface resolution order is such that base interfaces are listed after interfaces that extend them and, otherwise, interfaces are included in the order that they ...
