Class IndexedQueue

source code

object --+

Adds functionality to a IQueue object to track its usage.

Adds a new member function getIndex() and modify popChunk() and insertBackChunk() to keep a virtual pointer to the queue's first entry index.

Instance Methods
__init__(self, queue)
x.__init__(...) initializes x; see help(type(x)) for signature

Method Details

__init__(self, queue)

source code 

x.__init__(...) initializes x; see help(type(x)) for signature

Overrides: object.__init__
(inherited documentation)


Special descriptor for class __provides__

The descriptor caches the implementedBy info, so that
we can get declarations for objects without instance-specific
interfaces a bit quicker.

For example:

  >>> from zope.interface import Interface
  >>> class IFooFactory(Interface):
  ...     pass
  >>> class IFoo(Interface):
  ...     pass
  >>> class C(object):
  ...     implements(IFoo)
  ...     classProvides(IFooFactory)
  >>> [i.getName() for i in C.__provides__]

  >>> [i.getName() for i in C().__provides__]
