class documentation

class DeferredResource(resource.Resource): (source)

I wrap up a Deferred that will eventually result in a Resource object.

Class Variable	`isLeaf`	Signal if this IResource implementor is a "leaf node" or not. If True, getChildWithDefault will not be called on this Resource.
Method	`__init__`	Initialize.
Instance Variable	`d`	Undocumented
Method	`getChild`	Retrieve a 'child' resource from me.
Method	`render`	Render a given resource. See `IResource`'s render method.
Method	`_cbChild`	Undocumented
Method	`_ebChild`	Undocumented

Inherited from Resource:

Class Variable	`server`	Undocumented
Instance Variable	`children`	Undocumented
Method	`listStaticNames`	Undocumented
Method	`listStaticEntities`	Undocumented
Method	`listNames`	Undocumented
Method	`listEntities`	Undocumented
Method	`listDynamicNames`	Undocumented
Method	`listDynamicEntities`	Undocumented
Method	`getStaticEntity`	Undocumented
Method	`getDynamicEntity`	Undocumented
Method	`delEntity`	Undocumented
Method	`reallyPutEntity`	Undocumented
Method	`getChildWithDefault`	Retrieve a static or dynamically generated child resource from me.
Method	`getChildForRequest`	Undocumented
Method	`putChild`	Register a static child.
Method	`render_HEAD`	Default handling of HEAD method.

isLeaf = (source)

from twisted.web.resource.IResource

overrides twisted.web.resource.Resource.isLeaf

Signal if this IResource implementor is a "leaf node" or not. If True, getChildWithDefault will not be called on this Resource.

(type: int)

def __init__(self, d): (source)

overrides twisted.web.resource.Resource.__init__

Initialize.

d = (source)

Undocumented

def getChild(self, name, request): (source)

overrides twisted.web.resource.Resource.getChild

Retrieve a 'child' resource from me.

Implement this to create dynamic resource generation -- resources which are always available may be registered with self.putChild().

This will not be called if the class-level variable 'isLeaf' is set in your subclass; instead, the 'postpath' attribute of the request will be left as a list of the remaining path elements.

For example, the URL /foo/bar/baz will normally be:

  | site.resource.getChild('foo').getChild('bar').getChild('baz').

However, if the resource returned by 'bar' has isLeaf set to true, then the getChild call will never be made on it.

Parameters and return value have the same meaning and requirements as those defined by IResource.getChildWithDefault.

def render(self, request): (source)

from twisted.web.resource.IResource

overrides twisted.web.resource.Resource.render

Render a given resource. See IResource's render method.

I delegate to methods of self with the form 'render_METHOD' where METHOD is the HTTP that was used to make the request. Examples: render_GET, render_HEAD, render_POST, and so on. Generally you should implement those methods instead of overriding this one.

render_METHOD methods are expected to return a byte string which will be the rendered page, unless the return value is server.NOT_DONE_YET, in which case it is this class's responsibility to write the results using request.write(data) and then call request.finish().

Old code that overrides render() directly is likewise expected to return a byte string or NOT_DONE_YET.
