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`

Known subclasses: `twisted.words.protocols.jabber.xmlstream.XmlStreamFactory`

View In Hierarchy

Factory for XmlStream protocol objects as a reconnection client.

Method | `buildProtocol` | Create a protocol instance.

Inherited from `XmlStreamFactoryMixin`:

Method | `__init__` | Undocumented
Instance Variable | `args` | Positional arguments passed to the protocol upon instantiation.
Instance Variable | `kwargs` | Keyword arguments passed to the protocol upon instantiation.

Inherited from `BootstrapMixin` (via `XmlStreamFactoryMixin`):

Method | `addBootstrap` | Add a bootstrap event handler.
Method | `installBootstraps` | Install registered bootstrap observers.
Method | `removeBootstrap` | Remove a bootstrap event handler.
Instance Variable | `bootstraps` | The list of registered bootstrap event observers.

Inherited from `ReconnectingClientFactory` (via `XmlStreamFactoryMixin`, `BootstrapMixin`):

Method | `__getstate__` | Remove all of the state which is mutated by connection attempts and failures, returning just the state which describes how reconnections should be attempted. This will make the unserialized instance behave just as this one did when it was first instantiated.
Method | `clientConnectionFailed` | Called when a connection has failed to connect.
Method | `clientConnectionLost` | Called when an established connection is lost.
Method | `resetDelay` | Call this method after a successful connection: it resets the delay and the retry counter.
Method | `retry` | Have this connector connect again, after a suitable delay.
Method | `stopTrying` | Put a stop to any attempt to reconnect in progress.
Instance Variable | `clock` | The clock used to schedule reconnection. It's mainly useful to be parametrized in tests. If the factory is serialized, this attribute will not be serialized, and the default value (the reactor) will be restored when deserialized.
Instance Variable | `connector` | Undocumented
Instance Variable | `continueTrying` | Undocumented
Instance Variable | `delay` | Undocumented
Instance Variable | `factor` | A multiplicitive factor by which the delay grows
Instance Variable | `initialDelay` | Delay for the first reconnection attempt.
Instance Variable | `jitter` | Percentage of randomness to introduce into the delay length to prevent stampeding.
Instance Variable | `maxDelay` | Maximum number of seconds between connection attempts.
Instance Variable | `maxRetries` | Maximum number of consecutive unsuccessful connection attempts, after which no further connection attempts will be made. If this is not explicitly set, no maximum is applied.
Instance Variable | `retries` | Undocumented
Instance Variable | `_callID` | Undocumented

Inherited from `ClientFactory` (via `XmlStreamFactoryMixin`, `BootstrapMixin`, `ReconnectingClientFactory`):

Method | `startedConnecting` | Called when a connection has been started.

Inherited from `Factory` (via `XmlStreamFactoryMixin`, `BootstrapMixin`, `ReconnectingClientFactory`, `ClientFactory`):

Class Method | `forProtocol` | Create a factory for the given protocol.
Method | `doStart` | Make sure startFactory is called.
Method | `doStop` | Make sure stopFactory is called.
Method | `logPrefix` | Describe this factory for log messages.
Method | `startFactory` | This will be called before I begin listening on a Port or Connector.
Method | `stopFactory` | This will be called before I stop listening on all Ports/Connectors.
Class Variable | `noisy` | Undocumented
Class Variable | `protocol` | Undocumented
Instance Variable | `numPorts` | Undocumented

def buildProtocol(self, addr): (source)
from `twisted.internet.interfaces.IProtocolFactory`
overrides `twisted.words.xish.xmlstream.XmlStreamFactoryMixin.buildProtocol`

Create a protocol instance.

Overrides `XmlStreamFactoryMixin.buildProtocol` to work with a `ReconnectingClientFactory`. As this is called upon having an connection established, we are resetting the delay for reconnection attempts when the connection is lost again.
