  • Method Details

    • getMessageGroupFactory

      protected MessageGroupFactory getMessageGroupFactory()
      Overrides:
      getMessageGroupFactory in class AbstractBatchingMessageGroupStore

    • setExpiryCallbacks

      public void setExpiryCallbacks(Collection<MessageGroupStore.MessageGroupCallback> expiryCallbacks)
      Convenient injection point for expiry callbacks in the message store. Each of the callbacks provided will simply be registered with the store using registerMessageGroupExpiryCallback(MessageGroupCallback).
      Parameters:
      expiryCallbacks - the expiry callbacks to add

    • isTimeoutOnIdle

      public boolean isTimeoutOnIdle()

    • setTimeoutOnIdle

      public void setTimeoutOnIdle(boolean timeoutOnIdle)
      Allows you to override the rule for the timeout calculation. Typical timeout is based from the time the MessageGroup was created. If you want the timeout to be based on the time the MessageGroup was idling (e.g., inactive from the last update) invoke this method with 'true'. Default is 'false'.
      Parameters:
      timeoutOnIdle - The boolean.

    • setLazyLoadMessageGroups

      public void setLazyLoadMessageGroups(boolean lazyLoadMessageGroups)
      Specify if the result of the BasicMessageGroupStore.getMessageGroup(Object) should be wrapped to the PersistentMessageGroup - a lazy-load proxy for messages in group Defaults to true.

      The target logic is based on the SimpleMessageGroupFactory.GroupType.PERSISTENT.

      Parameters:
      lazyLoadMessageGroups - the boolean flag to use.

    • setLockRegistry

      public final void setLockRegistry(LockRegistry lockRegistry)
      Specify the type of the LockRegistry to ensure atomic operations
      Parameters:
      lockRegistry - lockRegistryType
      Since:
      6.5

    • getLockRegistry

      protected LockRegistry getLockRegistry()

    • registerMessageGroupExpiryCallback

      public void registerMessageGroupExpiryCallback(MessageGroupStore.MessageGroupCallback callback)
      Description copied from interface: MessageGroupStore
      Register a callback for when a message group is expired through MessageGroupStore.expireMessageGroups(long).
      Specified by:
      registerMessageGroupExpiryCallback in interface MessageGroupStore
      Parameters:
      callback - A callback to execute when a message group is cleaned up.

    • expireMessageGroups

      @ManagedOperation public int expireMessageGroups(long timeout)
      Description copied from interface: MessageGroupStore
      Extract all expired groups (whose timestamp is older than the current time less the threshold provided) and call each of the registered callbacks on them in turn. For example: call with a timeout of 100 to expire all groups that were created more than 100 milliseconds ago, and are not yet complete. Use a timeout of 0 (or negative to be on the safe side) to expire all message groups.
      Specified by:
      expireMessageGroups in interface MessageGroupStore
      Parameters:
      timeout - the timeout threshold to use
      Returns:
      the number of message groups expired

    • copy

      protected MessageGroup copy(MessageGroup group)
      Used by expireMessageGroups. We need to return a snapshot of the group at the time the reaper runs, so we can properly detect if the group changed between now and the attempt to expire the group. Not necessary for persistent stores, so the default behavior is to just return the group.
      Parameters:
      group - The group.
      Returns:
      The group, or a copy.
