t.w._.LengthEnforcingConsumer : class documentation

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

Instance Variables	_length	The number of bytes remaining to be written.
	_producer	The `IBodyProducer` which is writing to this consumer.
	_consumer	The consumer to which at most `_length` bytes will be forwarded.
	_finished	A `Deferred` which will be fired with a `Failure` if too many bytes are written to this consumer.

Method	__init__	Undocumented
Method	write	Write `bytes` to the underlying consumer unless `_noMoreWritesExpected` has been called or there are/have been too many bytes.
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.

def __init__(self, producer, consumer, finished): (source)

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.

Raises WrongBodyLength If not enough bytes have been written.
