Class SessionLock.SubsessionLockCount

  • All Implemented Interfaces:
    LockCountManager<SessionToken>
    Enclosing class:
    SessionLock
    @Deprecated
public static class SessionLock.SubsessionLockCount
extends Object
implements LockCountManager<SessionToken>
    Deprecated.
    This does not work as intended. Use SessionLock.UpwardSubtreeLockCount instead.
    A LockCountManager counting session tokens considering session tokens and their subsessions (but not vice versa!) as equal. This means, a child session will have a lock if a session of a parent level has the lock. Parent sessions may "upgrade" (by acquisition) and "downgrade" (by release) a lock.
    This locks a specific session token subtree in the session token tree and therefore allows siblings to have the lock concurrently.

      • hasLock

        public boolean hasLock​(SessionToken session)
        Deprecated.
        Description copied from interface: LockCountManager

        Parameters:
        session - The object which is checked whether it holds a lock.
        Returns:
        Whether the designated object has a lock at least once.

      • hasLocks

        public boolean hasLocks()
        Deprecated.
        Description copied from interface: LockCountManager
        Returns whether this lock count manager knows at least one object that has a lock.
        Specified by:
        hasLocks in interface LockCountManager<SessionToken>
        Returns:
        Whether at least one object has a lock.

      • getLockOwner

        public String getLockOwner()
        Deprecated.
        Description copied from interface: LockCountManager
        Returns a string representation of one object that currently has a lock. This can be used for user information or tracking purpose. A locking object may not be returned since this would allow to unlock.
        Specified by:
        getLockOwner in interface LockCountManager<SessionToken>
        Returns:
        A string representation of one object that currently has a lock.

        public int increaseAndGetLockCount​(SessionToken session)
        Deprecated.
        Description copied from interface: LockCountManager
        Increases the number of times the designated object holds the lock.
        Specified by:

        Parameters:
        session - The object which has acquired the lock (once again).
        Returns:
        The number of times the designated object has the lock after the increment.

      • decreaseAndGetLockCount

        Specified by:
        decreaseAndGetLockCount in interface LockCountManager<SessionToken>
        Parameters:
        session - The object which has released the lock (once again).
        Returns:
        The number of times the designated object has the lock after the decrement.
