An IConsumer proxy which enforces an exact length requirement on the total data written to it.

Method __init__ Undocumented
Method write Write bytes to the underlying consumer unless _noMoreWritesExpected has been called or there are/have been too many bytes.
Instance Variable _length The number of bytes remaining to be written.
Instance Variable _producer The IBodyProducer which is writing to this consumer.
Instance Variable _consumer The consumer to which at most _length bytes will be forwarded.
Instance Variable _finished A Deferred which will be fired with a Failure if too many bytes are written to this consumer.
Method _allowNoMoreWrites Indicate that no additional writes are allowed. Attempts to write after calling this method will be met with an exception.
Method _noMoreWritesExpected Called to indicate no more bytes will be written to this consumer. Check to see that the correct number have been written.
_length =
The number of bytes remaining to be written.

Undocumented
def _allowNoMoreWrites(self): (source)

Indicate that no additional writes are allowed. Attempts to write after calling this method will be met with an exception.

def write(self, bytes): (source)

Write bytes to the underlying consumer unless _noMoreWritesExpected has been called or there are/have been too many bytes.

def _noMoreWritesExpected(self): (source)

Called to indicate no more bytes will be written to this consumer. Check to see that the correct number have been written.

RaisesWrongBodyLengthIf not enough bytes have been written.
