  • 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

    • visitContinuousAggregation

      default boolean visitContinuousAggregation(long lOldCacheId, int nFormat, Binary binDefinition)
      Apply the visitor to a continuous aggregation definition.
      Parameters:
      lOldCacheId - the persisted cache identifier
      nFormat - the definition format version
      binDefinition - the serialized definition
      Returns:
      false to terminate the iteration

    • visitContinuousAggregationState

      default boolean visitContinuousAggregationState(long lOldCacheId, int nFormat, int nPartition, long lOwnershipVersion, long lDataVersion, Binary binDefinition, Binary binState)
      Apply the visitor to a continuous aggregation partition-state checkpoint.
      Parameters:
      lOldCacheId - the persisted cache identifier
      nFormat - the state format version
      nPartition - the partition identifier
      lOwnershipVersion - the ownership version
      lDataVersion - the logical data version
      binDefinition - the definition fingerprint
      binState - the serialized state envelope
