L{StringTransport} has a number of attributes which are not part of any of the interfaces it claims to implement. These attributes are provided for testing purposes. Implementation code should not use any of these attributes; they are not provided by other transports. @ivar disconnecting: A C{bool} which is C{False} until L{loseConnection} is called, then C{True}. @ivar disconnected: A C{bool} which is C{False} until L{abortConnection} is called, then C{True}. @ivar producer: If a producer is currently registered, C{producer} is a reference to it. Otherwise, L{None}. @ivar streaming: If a producer is currently registered, C{streaming} refers to the value of the second parameter passed to C{registerProducer}. @ivar hostAddr: L{None} or an object which will be returned as the host address of this transport. If L{None}, a nasty tuple will be returned instead. @ivar peerAddr: L{None} or an object which will be returned as the peer address of this transport. If L{None}, a nasty tuple will be returned instead. @ivar producerState: The state of this L{StringTransport} in its capacity as an L{IPushProducer}. One of C{'producing'}, C{'paused'}, or C{'stopped'}. @ivar io: A L{io.BytesIO} which holds the data which has been written to this transport since the last call to L{clear}. Use L{value} instead of accessing this directly. @ivar _lenient: By default L{StringTransport} enforces that L{resumeProducing} is not called after the connection is lost. This is to ensure that any code that does call L{resumeProducing} after the connection is lost is not blindly expecting L{resumeProducing} to have any impact. However, if your test case is calling L{resumeProducing} after connection close on purpose, and you know it won't block expecting further data to show up, this flag may safely be set to L{True}. Defaults to L{False}. @type lenient: L{bool} FN� producingc C s4 | � � |d k r|| _|d k r$|| _d| _|| _d S rJ )�clear�hostAddr�peerAddr� connected�_lenient)r. � hostAddressZ peerAddressZlenientr0 r0 r1 rD � s zStringTransport.__init__c C s t � | _dS )z� Discard all data written to this transport so far.
