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 reading methods that needs to be implemented by derived classes. All other content access methods make use of this in their underlying implementations.
Once the stream is provided to a client it should remain active (subject to any timeouts) until closed by the client.
OutputStreamAll resources will be closed automatically.
String, but limiting
the string size to a given number of characters.
If the encoding is known then it will be used otherwise the default system byte[] to String conversion will be used.
All resources will be closed automatically.
All the content is streamed into memory. So, like the interface said, be careful with this method.
