        "description": "repoze.bfg.traversaladapter\r\n===========================\r\n\r\nAn alternate implementation of the\r\n``repoze.bfg.interfaces.ITraverserFactory`` (a \"traverser\") which\r\nallows you to register an adapter factory for the type or interface(s) of\r\nobjects encountered during traversal. This is a generalization of the\r\n``repoze.bfg.traversalwrapper`` package which automatically wraps each\r\ntraversed object into a location-aware proxy.\r\n\r\nTo enable this custom traverser factory, you need to add a dependency on\r\n``repoze.bfg.traversaladapter`` to your application and replace the default\r\ntraverser factory in the ``configure.zcml`` configuration file like this: ::\r\n\r\n    <adapter\r\n        factory=\"repoze.bfg.traversaladapter.ModelGraphTraverser\"\r\n        provides=\"repoze.bfg.interfaces.ITraverserFactory\"\r\n        for=\"*\"\r\n        />\r\n\r\nGiven a simple factory for adapters for a model class ``mymodule.Foo``\r\ndefined in the module ``mymodule`` like this ::\r\n\r\n    def foo_factory(foo, parent, name):\r\n        return FooAdapter(foo, parent, name)\r\n\r\nyou could then register ``foo_factory`` as a traversal adapter factory as\r\nfollows: ::\r\n\r\n    <adapter\r\n        factory=\"mymodule.foo_factory\"\r\n        provides=\"repoze.bfg.traversaladapter.ITraversalAdapterFactory\"\r\n        for=\"mymodule.Foo\"\r\n        />\r\n\r\nIf ``Foo`` was implementing the interface ``mymodule.IFoo``, the following\r\nregistration would also work: ::\r\n\r\n    <adapter\r\n        factory=\"mymodule.foo_factory\"\r\n        provides=\"repoze.bfg.traversaladapter.ITraversalAdapterFactory\"\r\n        for=\"mymodule.IFoo\"\r\n        />\r\n\r\nDuring traversal of your ``repoze.bfg`` application, each object of type\r\n``Foo`` will then automatically be wrapped in a ``FooAdapter`` instance.\r\n\r\nNote that the registered factory always gets the current model object, its\r\nparent and its name passed as arguments. If your ``FooAdapter`` class was set\r\nup to receive a ``Foo`` instance, a parent object, and a name string in its\r\nconstructor like so ::\r\n\r\n    class FooAdapter(object):\r\n        def __init__(self, foo, parent, name):\r\n            self.foo = foo\r\n            self.parent = parent\r\n            self.name = name\r\n\r\nyou could register the adapter class itself as the adapter factory.\r\n\r\nSee the ``repoze.bfg.traversaladapter.tests.TraversalAdapterTests``\r\nmodule for further examples.",
