  • Method Details

    • visitCacheEntry

      boolean visitCacheEntry(long lOldCacheId, Binary binKey, Binary binValue)
      Apply the visitor to the specified cache entry (key-value pair).
      Parameters:
      lOldCacheId - the persisted cache-id
      binKey - the cache key
      binValue - the cache value
      Returns:
      false to terminate the iteration

    • visitListener

      boolean visitListener(long lOldCacheId, Binary binKey, long lListenerId, boolean fLite)
      Apply the visitor to the specified cache entry listener.
      Parameters:
      lOldCacheId - the persisted cache-id
      binKey - the cache key
      lListenerId - the service-unique identifier of the listening member
      fLite - true iff the listener should receive "lite" events
      Returns:
      false to terminate the iteration

    • visitLock

      boolean visitLock(long lOldCacheId, Binary binKey, long lHolderId, long lHolderThreadId)
      Apply the visitor to the specified cache entry lock.
      Parameters:
      lOldCacheId - the persisted cache-id
      binKey - the cache key
      lHolderId - the service-unique identifier of the lock holder
      lHolderThreadId - the thread-id of the lock holder
      Returns:
      false to terminate the iteration

    • visitIndex

      boolean visitIndex(long lOldCacheId, Binary binExtractor, Binary binComparator)
      Apply the visitor to the specified cache index.
      Parameters:
      lOldCacheId - the persisted cache-id
      binExtractor - the index extractor
      binComparator - the index comparator
      Returns:
      false to terminate the iteration

    • visitTrigger

      boolean visitTrigger(long lOldCacheId, Binary binTrigger)
      Apply the visitor to the specified trigger.
      Parameters:
      lOldCacheId - the persisted cache-id
      binTrigger - the trigger
      Returns:
      false to terminate the iteration
