search in docstrings

Search bar offers the following options:

- Term presence. The below example searches for documents that must contain “foo”, might contain “bar” and must not contain “baz”: `+foo bar -baz`
- Wildcards. The below example searches for documents with words beginning with “foo”: `foo*`
- Search in specific fields. The following search matches all objects in "twisted.mail" that matches “search”: `+qname:twisted.mail.* +search`

  Possible fields: 'name', 'qname' (fully qualified name), 'docstring', and 'kind'. Last two fields are only applicable if "search in docstrings" is enabled.

- Fuzzy matches. The following search matches all documents that have a word within 1 edit distance of “foo”: `foo~1`

`class DeferredResource(resource.Resource): (source)`

View In Hierarchy

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

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

def __init__(self, d): (source)
overrides `twisted.web.resource.Resource.__init__`

Initialize.

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.

`IResource.render`

isLeaf: `int` = (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.
