Class CommitTracker

  • All Implemented Interfaces:
    Runnable
    public final class CommitTracker
extends Object
implements Runnable
    Helper class for tracking autoCommit state.

    Note: This is purely an implementation detail of autoCommit and will definitely change in the future, so the interface should not be relied-upon

    Note: all access must be synchronized.

    Public for tests.
