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`

Undocumented

Method | `__init__` | Undocumented
Method | `abortConnection` | Abort the connection. Same as `loseConnection`.
Method | `getHost` | Similar to getPeer, but returns an address describing this side of the connection.
Method | `getPeer` | Get the remote address of this connection.
Method | `loseConnection` | Close my connection, after writing all pending data.
Method | `registerProducer` | Register to receive data from a producer.
Method | `unregisterProducer` | Stop consuming data from a producer, without disconnecting.
Method | `write` | Write some data to the physical connection, in sequence, in a non-blocking fashion.
Method | `writeSequence` | Write an iterable of byte strings to the physical connection.

def __init__(self, q): (source)

Undocumented

def abortConnection(self): (source)

Abort the connection. Same as `loseConnection`.

def getHost(self): (source)
from `twisted.internet.interfaces.ITransport`

Similar to getPeer, but returns an address describing this side of the connection.

Returns
An `IAddress` provider.

def getPeer(self): (source)
from `twisted.internet.interfaces.ITransport`

Get the remote address of this connection.

Treat this method with caution. It is the unfortunate result of the CGI and Jabber standards, but should not be considered reliable for the usual host of reasons; port forwarding, proxying, firewalls, IP masquerading, etc.

Returns
An `IAddress` provider.

def loseConnection(self): (source)
from `twisted.internet.interfaces.ITransport`

Close my connection, after writing all pending data.

Note that if there is a registered producer on a transport it will not be closed until the producer has been unregistered.

def registerProducer(self, producer, streaming): (source)
from `twisted.internet.interfaces.IConsumer`

Register to receive data from a producer.

This sets self to be a consumer for a producer. When this object runs out of data (as when a send(2) call on a socket succeeds in moving the last data from a userspace buffer into a kernelspace buffer), it will ask the producer to resumeProducing().

For `IPullProducer` providers, `resumeProducing` will be called once each time data is required.

For `IPushProducer` providers, `pauseProducing` will be called whenever the write buffer fills up and `resumeProducing` will only be called when it empties. The consumer will only call `resumeProducing` to balance a previous `pauseProducing` call; the producer is assumed to start in an un-paused state.

Parameters
producer | Undocumented
streaming | `True` if `producer` provides `IPushProducer`, `False` if `producer` provides `IPullProducer`.
Raises
`RuntimeError` | If a producer is already registered.

def unregisterProducer(self): (source)
from `twisted.internet.interfaces.IConsumer`

Stop consuming data from a producer, without disconnecting.

def write(self, data): (source)
from `twisted.internet.interfaces.ITransport`

Write some data to the physical connection, in sequence, in a non-blocking fashion.

If possible, make sure that it is all written. No data will ever be lost, although (obviously) the connection may be closed before it all gets through.

Parameters
data | The data to write.

def writeSequence(self, iovec): (source)
from `twisted.internet.interfaces.ITransport`

Write an iterable of byte strings to the physical connection.

If possible, make sure that all of the data is written to the socket at once, without first copying it all into a single byte string.

Parameters
iovec | Undocumented
data | The data to write.
