      • GarbageCollectCommand

        protected GarbageCollectCommand​(Repository repo)
        Constructor for GarbageCollectCommand.
        Parameters:
        repo - a Repository object.

    • Method Detail

      • setProgressMonitor

        public GarbageCollectCommand setProgressMonitor​(ProgressMonitor monitor)
        Set progress monitor
        Parameters:
        monitor - a progress monitor
        Returns:
        this instance

      • setExpire

        public GarbageCollectCommand setExpire​(java.util.Date expire)
        During gc() or prune() each unreferenced, loose object which has been created or modified after expire will not be pruned. Only older objects may be pruned. If set to null then every object is a candidate for pruning. Use GitDateParser to parse time formats used by git gc.
        Parameters:
        expire - minimal age of objects to be pruned.
        Returns:
        this instance

      • setAggressive

        public GarbageCollectCommand setAggressive​(boolean aggressive)
        Whether to use aggressive mode or not. If set to true JGit behaves more similar to native git's "git gc --aggressive". If set to true compressed objects found in old packs are not reused but every object is compressed again. Configuration variables pack.window and pack.depth are set to 250 for this GC.
        Parameters:
        aggressive - whether to turn on or off aggressive mode
        Returns:
        this instance

      • setPreserveOldPacks

        public GarbageCollectCommand setPreserveOldPacks​(boolean preserveOldPacks)
        Whether to preserve old pack files instead of deleting them.
        Parameters:
        preserveOldPacks - whether to preserve old pack files
        Returns:
        this instance
        Since:

      • setPrunePreserved

        public GarbageCollectCommand setPrunePreserved​(boolean prunePreserved)
