Class: IEventThread

The event thread class must store a list of handles to execute and must define a run method which actually executes the handles.

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.

getName (self)

Returns the name of the object.

getTaggedValue (self, tag)

interfaces (self)

Return an iterator for the interfaces in the specification

for example:

>>> i.next().getName()
'I1'
>>> list(i)
[]

isEqualOrExtendedBy (self, other)
