Package buildbot :: Package status :: Module persistent_queue :: Class DiskQueue

Class DiskQueue

object --+
         |
        DiskQueue

Keeps a list of abstract items and serializes it to the disk.

Use pickle for serialization.

Instance Methods

__init__(self, path, maxItems=None, pickleFn=<built-in function dumps>, unpickleFn=<built-in function loads>)
x.__init__(...) initializes x; see help(type(x)) for signature

popChunk(self, nbItems=None)

source code

save(self)

Method Details

init(self, path, maxItems=None, pickleFn=<built-in function dumps>, unpickleFn=<built-in function loads>)
(Constructor)

source code

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

Overrides: object.__init__

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__]
  ['IFooFactory']

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