    • supports

      public boolean supports(Event event, Context context)
      Description copied from interface: Callback
      Whether this callback supports this event or not. This is primarily meant as a way to optimize event handling by avoiding unnecessary connection state setups for events that will not be handled anyway.
      Specified by:
      supports in interface Callback
      Parameters:
      event - The event to check.
      context - The context for this event.
      Returns:
      true if it can be handled, false if not.

    • canHandleInTransaction

      public boolean canHandleInTransaction(Event event, Context context)
      Description copied from interface: Callback
      Whether this event can be handled in a transaction or whether it must be handled outside a transaction instead. In the vast majority of the cases the answer will be true. Only in the rare cases where non-transactional statements are executed should this return false. This method is called before Callback.handle(Event, Context) in order to determine in advance whether a transaction can be used or not.
      Specified by:
      canHandleInTransaction in interface Callback
      Parameters:
      event - The event to check.
      context - The context for this event.
      Returns:
      true if it can be handled within a transaction (almost all cases). false if it must be handled outside a transaction instead (very rare).

    • handle

      public void handle(Event event, Context context)
      Description copied from interface: Callback
      Handles this MigrateDB lifecycle event.
      Specified by:
      handle in interface Callback
      Parameters:
      event - The event to handle.
      context - The context for this event.

    • getCallbackName

      public String getCallbackName()
      Description copied from interface: Callback
      The callback name, MigrateDB will use this to sort the callbacks alphabetically before executing them
      Specified by:
      getCallbackName in interface Callback
      Returns:
      The callback name
