Use FileChannel.transferTo() instead of MappedByteBuffer
--------------------------------------------------------
Key: DEFT-185
URL: https://issues.apache.org/jira/browse/DEFT-185
Project: Deft
Issue Type: New Feature
Components: Core
Affects Versions: 0.4.0
Reporter: Séven Le Mesle
Assignee: Séven Le Mesle
Fix For: 0.4.0
Using a MappedByteBuffer to deliver static content is not good as we can not
use kernel sendFile directive when available.
The FileChannel.transferTo() allows for such a feature and would be far better.
Even notice that MappedByteBuffer is memory consuming, with transferTo() on his
side is light and efficient (no buffers involved for many OS).
The only backside is that we need to take great care of the opened files !
Work would be to replace MBB stuff with the transferTo call and store a
FileInputStream as key attachment, the underlying FileChannel can be used to
maintain position.
