class ulauncher.utils.SimpleWebSocketServer.WebSocket(server, sock, address)
close(status=1000, reason='')

Send Close frame to the client. The underlying socket is only closed when the client acknowledges the Close frame.

status is the closing identifier. reason is the reason for the close.

handleClose()

Called when a websocket server gets a Close frame from a client.

handleConnected()

Called when a websocket client connects to the server.

handleMessage()

Called when websocket frame is received. To access the frame data call self.data.

If the frame is Text then self.data is a unicode object. If the frame is Binary then self.data is a bytearray object.

sendFragment(data)

see sendFragmentStart()

If data is a unicode object then the frame is sent as Text. If the data is a bytearray object then the frame is sent as Binary.

sendFragmentEnd(data)

see sendFragmentEnd()

If data is a unicode object then the frame is sent as Text. If the data is a bytearray object then the frame is sent as Binary.

sendFragmentStart(data)

Send the start of a data fragment stream to a websocket client. Subsequent data should be sent using sendFragment(). A fragment stream is completed when sendFragmentEnd() is called.

If data is a unicode object then the frame is sent as Text. If the data is a bytearray object then the frame is sent as Binary.

sendMessage(data)

Send websocket data frame to the client.

If data is a unicode object then the frame is sent as Text. If the data is a bytearray object then the frame is sent as Binary.

ulauncher.utils.SortedCollection module

class ulauncher.utils.SortedCollection.SortedCollection(iterable=(), key=None)

Sequence sorted by a key function.

SortedCollection() is much easier to work with than using bisect() directly. It supports key functions like those use in sorted(), min(), and max(). The result of the key function call is saved so that keys can be searched efficiently.

Instead of returning an insertion-point which can be hard to interpret, the five find-methods return a specific item in the sequence. They can scan for exact matches, the last item less-than-or-equal to a key, or the first item greater-than-or-equal to a key.

Once found, an item’s ordinal position can be located with the index() method. New items can be added with the insert() and insert_right() methods. Old items can be deleted with the remove() method.

The usual sequence methods are provided to support indexing, slicing, length lookup, clearing, copying, forward and reverse iteration, contains checking, item counts, item removal, and a nice looking repr.

Finding and indexing are O(log n) operations while iteration and insertion are O(n). The initial sort is O(n log n).

The key function is stored in the ‘key’ attibute for easy introspection or so that you can assign a new key function (triggering an automatic re-sort).

In short, the class was designed to handle all of the common use cases for bisect but with a simpler API and support for key functions.
