Methods

Attributes

Class: ISet

The basic interface for set objects.

Methods

changed (self, originally_changed)

We, or something we depend on, have changed

deferred (self)

Return a defered class corresponding to the interface.

direct (self, name)

extends (self, interface, strict=True)

Does the specification extend the given interface?

Test whether an interface in the specification extends the given interface

Examples:

>>> from zope.interface import Interface
>>> from 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))
1
>>> 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
>>> I2.extends(I2)
0
>>> I2.extends(I2, False)
1
>>> I2.extends(I2, strict=False)
1

get (self, name, default=None)

Query for an attribute description

getBases (self)

getDescriptionFor (self, name)

Return the attribute description for the given name.

getDoc (self)

Returns the documentation for the object.

getName (self)

Returns the name of the object.

getTaggedValue (self, tag)

Returns the value associated with 'tag'.

getTaggedValueTags (self)

Returns a list of all tags.

interfaces (self)

Return an iterator for the interfaces in the specification

for example:

>>> from zope.interface import Interface
>>> class I1(Interface): pass
...
>>>
>>> i = I1.interfaces()
>>> i.next().getName()
'I1'
>>> list(i)
[]

isEqualOrExtendedBy (self, other)

Same interface or extends?

names (self, all=False)

Return the attribute names defined by the interface.

namesAndDescriptions (self, all=False)

queryDescriptionFor (self, name, default=None)

queryTaggedValue (self, tag, default=None)

Returns the value associated with 'tag'.

setTaggedValue (self, tag, value)

Associates 'value' with 'key'.

subscribe (self, dependent)

unsubscribe (self, dependent)

validateInvariants (self, obj, errors=None)

validate object to defined invariants.
