        "description": "============\ndolmen.field\n============\n\nThe `dolmen.field` package provides additional generic fields to\nextend `zope.schema`.\n\n\nConfiguration fields\n====================\n\nThe configuration fields are used for description and constraints, to\nimpose a consistent schema and data model.\n\nGlobalClass\n-----------\n\n`GlobalClass` is a field requiring a valid Interface class. It can be\nused for factories and other components that need to store an\ninterface with the possibility to check and verify the consistency of\nthe given value::\n\n  >>> from zope.interface import Interface\n  >>> from dolmen.field import GlobalClass, IClassField\n\n  >>> class IDummy(Interface):\n  ...     def shall_fail():\n  ...         pass\n\n  >>> class Dummy(object):\n  ...     pass\n\nOf course, it must be a valid interface::\n\n  >>> field = GlobalClass(\n  ...             title=u'a class field',\n  ...             schema=object\n  ...             )\n  Traceback (most recent call last):\n  ...\n  WrongType: <type 'object'> is not a valid Interface\n\nThe interface will be used to validate the class::\n   \n  >>> field = GlobalClass(\n  ...             title=u'a class field',\n  ...             schema=IDummy\n  ...             )\n\n  >>> field.schema\n  <InterfaceClass dolmen.field.tests.IDummy>\n  >>> IClassField.providedBy(field)\n  True\n\nWe make sure the `interface` attribute is not touched::\n   \n  >>> print field.interface\n  None\n\nIn a first time, we make sure the class implements the needed interface::\n\n  >>> field._validate(Dummy)\n  Traceback (most recent call last):\n  ...\n  ConstraintNotSatisfied: <class 'dolmen.field.tests.Dummy'> does not implement <InterfaceClass dolmen.field.tests.IDummy>\n  \n  >>> from zope.interface import classImplements\n  >>> classImplements(Dummy, IDummy)\n  >>> IDummy.implementedBy(Dummy)\n  True\n\nThen the interface acts as a strict validator::\n\n  >>> field._validate(Dummy)\n  Traceback (most recent call last):\n  ...\n  BrokenImplementation: An object has failed to implement interface <InterfaceClass dolmen.field.tests.IDummy>\n  <BLANKLINE>\n  The shall_fail attribute was not provided.\n  <BLANKLINE>\n\n  >>> Dummy.shall_fail = lambda x: u'not'\n  >>> field._validate(Dummy) is None\n  True\n\n\nChangelog\n=========\n\n0.3 (2009-10-25)\n----------------\n\n.. attention: \n\n  This version is *not* compatible with the previous ones.\n\n* Refactored the field to use the 'schema' attribute instead of\n  'interface'. The attribute name 'interface' was conflicting with\n  other fields manipulating packages. \n\n* Now using a README.txt instead of inline doctests, for more\n  readability.\n\n\n0.2 (2009-06-09)\n----------------\n\n* Initial Pypi release\n\n\n0.1 (2009-05-03)\n----------------\n\n* Internal release",
