twisted.internet.test.test_filedescriptor.MemoryFile

Method	__init__
Method	startWriting	Start waiting for write availability.
Method	stopWriting	Stop waiting for write availability.
Method	writeSomeData	Copy at most `self._freeSpace` bytes from `data` into `self._written`.
Instance Variable	_written	A `list` of `bytes` which have been accepted as written.
Instance Variable	_freeSpace	A `int` giving the number of bytes which will be accepted by future writes.

Inherited from FileDescriptor:

Method	connectionLost	The connection was lost.
Method	doRead	Called when data is available for reading.
Method	doWrite	Called when data can be written.
Method	writeConnectionLost	Indicates write connection was lost.
Method	readConnectionLost	Indicates read connection was lost.
Method	write	Reliably write some data.
Method	writeSequence	Reliably write a sequence of data.
Method	loseConnection	Close the connection at the next available opportunity.
Method	loseWriteConnection	Undocumented
Method	stopReading	Stop waiting for read availability.
Method	startReading	Start waiting for read availability.
Method	stopConsuming	Stop consuming data.
Method	resumeProducing	Resume producing data.
Method	pauseProducing	Pause producing data.
Method	stopProducing	Stop producing data.
Method	fileno	File Descriptor number for select().
Method	_postLoseConnection	Called after a loseConnection(), when all data has been written.
Method	_closeWriteConnection	Undocumented
Method	_isSendBufferFull	Determine whether the user-space send buffer for this transport is full or not.
Method	_maybePauseProducer	Possibly pause a producer, if there is one and the send buffer is full.

Inherited from _ConsumerMixin (via FileDescriptor):

Instance Variable	producer	`None` if no producer is registered, otherwise the registered producer.
Instance Variable	producerPaused	A flag indicating whether the producer is currently paused. (type: `bool`)
Instance Variable	streamingProducer 0	A flag indicating whether the producer was registered as a streaming (ie push) producer or not (ie a pull producer). This will determine whether the consumer may ever need to pause and resume it, or if it can merely call `resumeProducing` on it when buffer space is available.
Instance Variable	streamingProducer	`bool` or `int`
Method	registerProducer	Register to receive data from a producer.
Method	unregisterProducer	Stop consuming data from a producer, without disconnecting.

Inherited from _LogOwner (via FileDescriptor):

Method	logPrefix	Override this method to insert custom logging behavior. Its return value will be inserted in front of every line. It may be called more times than the number of output lines.
Method	_getLogPrefix	Determine the log prefix to use for messages related to `applicationObject`, which may or may not be an `interfaces.ILoggingContext` provider.

_written =

A list of bytes which have been accepted as written.

_freeSpace =

A int giving the number of bytes which will be accepted by future writes.

def __init__(self):

overrides twisted.internet.abstract.FileDescriptor.__init__

Parameters reactor An IReactorFDSet provider which this descriptor will use to get readable and writeable event notifications. If no value is given, the global reactor will be used.

def startWriting(self):

overrides twisted.internet.abstract.FileDescriptor.startWriting

Start waiting for write availability.

Call this to have this FileDescriptor be notified whenever it is ready for writing.

def stopWriting(self):

overrides twisted.internet.abstract.FileDescriptor.stopWriting

Stop waiting for write availability.

Call this to remove this selectable from being notified when it is ready for writing.

def writeSomeData(self, data):

overrides twisted.internet.abstract.FileDescriptor.writeSomeData

Copy at most self._freeSpace bytes from data into self._written.

Returns A int indicating how many bytes were copied from data.
