                            Controller

Known Subclasses:
  `LiveController`, `InputHandler`, `Page`, `DOMController`

A Controller which handles to events from the user. Such events are `web request', `form submit', etc.

I should be the IResource implementor for your Models (and `registerControllerForModel` makes this so).

Method Details

### getChild(self, name, request) Look for a factory method to create the object to handle the next segment of the URL. If a wchild_* method is found, it will be called to produce the Resource object to handle the next segment of the path. If a wchild_* method is not found, getDynamicChild will be called with the name and request. Parameters: `name` - The name of the child being requested. (type=string) `request` - The HTTP request being handled. (type=`twisted.web.server.Request`)

### getDynamicChild(self, name, request) This method is called when getChild cannot find a matching wchild_* method in the Controller. Override me if you wish to have dynamic handling of child pages. Should return a Resource if appropriate. Return None to indicate no resource found. Parameters: `name` - The name of the child being requested. (type=string) `request` - The HTTP request being handled. (type=`twisted.web.server.Request`)

### handle(self, request) By default, we don't do anything

### pageRenderComplete(self, request) Override this to recieve notification when the view rendering process is complete.

### render(self, request) Trigger any inputhandlers that were passed in to this Page, then delegate to the View for traversing the DOM. Finally, call gatheredControllers to deal with any InputHandlers that were constructed from any controller= tags in the DOM. gatheredControllers will render the page to the browser when it is done.

### setUp(self, request, *args) Parameters: `request` (type=`twisted.web.server.Request`)

### wchild_index(self, request) By default, we return ourself as the index. Override this to provide different behavior for a URL that ends in a slash.
