The root resource on the data center.

It does the main dispatching based on four mechanisms:

redirects -- one-segments fragments that redirect somewhere else. This is for "bad" shortcuts corresponding to input directory name exclusively (since it's so messy). These will not match if path has more than one segment.
statics -- first segment leads to a resource that gets passed any additional segments.
mappings -- first segment is replaced by something else, processing continues.
resource based -- consisting of an RD id, a service id, a renderer and possibly further segments.

The first three mechanisms only look at the first segment to determine any action (except that redirect is skipped if len(segments)>1).

The statics and mappings are configured on the class level.

locateChild(self, ctx, segments)

source code

Locate a child page of this one. ctx is a nevow.context.PageContext representing the parent Page, and segments is a tuple of each element in the URI. An tuple (page, segments) should be returned, where page is an instance of nevow.rend.Page and segments a tuple representing the remaining segments of the URI. If the child is not found, return NotFound instead.

locateChild is designed to be easily overridden to perform fancy lookup tricks. However, the default locateChild is useful, and looks for children in three places, in this order:

in a dictionary, self.children
a member of self named child_<childname>. This can be either an attribute or a method. If an attribute, it should be an object which can be adapted to IResource. If a method, it should take the context and return an object which can be adapted to IResource.
by calling self.childFactory(ctx, name). Name is a single string instead of a tuple of strings. This should return an object that can be adapted to IResource.
