Only the instance need be constructed. The required mimetype, encoding, etc will be copied across by this class.
This is the only of the content writing methods that needs to be implemented by derived classes. All other content access methods make use of this in their underlying implementations.
The channel returned to the client should remain open (subject to timeouts) until closed by the client. All lock detection, read-only access and other concurrency issues are dealt with during this operation. It remains possible that implementations will throw exceptions when the channel is closed.
The stream will notify any listeners according to the listener interface.
Underlying implementations use the truncate parameter to determine the
most effective means of providing access to the content.
