SequentialFile	createFileForLargeMessage(long messageID, StorageManager.LargeMessageExtension extension) Instantiates a SequentialFile to be used for storing a LargeServerMessage.
LargeServerMessage	createLargeMessage()
LargeServerMessage	createLargeMessage(long id, MessageInternal message) Creates a new LargeMessage with the given id.
void	freeDirectBuffer(ByteBuffer buffer) AIO has an optimized buffer which has a method to release it instead of the way NIO will release data based on GC.

performCachedLargeMessageDeletes

protected void performCachedLargeMessageDeletes()

Assumption is that this is only called with a writeLock on the StorageManager.

Specified by:

performCachedLargeMessageDeletes in class AbstractJournalStorageManager
