setRotationStrategy
,setArchiveStrategy
andsetPurgeStrategy
allow setting custom strategies to be used by theFileChannel
.These new functions take a non-null pointer and
FileChannel
owns the pointer after the call and will delete it when necessary.Also changed
FileChannel
to use a newNullRotationStrategy
andNullPurgeStrategy
instead of null pointers.One thing to note about these changes right now is that setting a property will still internally create a new strategy in
FileChannel
, overwriting the one provided to the set strategy functions. I think this is ok and I don't have any better ideas right now.Personally, I've wanted this ability with Poco at work for a while so that we can start each log file with the version of software. It's currently difficult to know what version a customer is using when they send us log files.
