      void handleTableLocationKeyAdded(@NotNull @NotNull LiveSupplier<ImmutableTableLocationKey> tableLocationKey)
      Notify the listener of a LiveSupplier<ImmutableTableLocationKey> encountered while initiating or maintaining the location subscription. This should occur at most once per location, but the order of delivery is not guaranteed. This addition is not part of any transaction, and is equivalent to handleTableLocationKeyAdded(tableLocationKey, null); by default.
      Parameters:
      tableLocationKey - The new table location key.

    • handleTableLocationKeyRemoved

      void handleTableLocationKeyRemoved(@NotNull @NotNull LiveSupplier<ImmutableTableLocationKey> tableLocationKey)
      Notify the listener of a LiveSupplier<ImmutableTableLocationKey> that has been removed. This removal is not part of any transaction, and is equivalent to handleTableLocationKeyRemoved(tableLocationKey, null); by default.
      Parameters:
      tableLocationKey - The table location key that was removed.

    • handleTableLocationKeysUpdate

      default void handleTableLocationKeysUpdate(@NotNull @NotNull Collection<LiveSupplier<ImmutableTableLocationKey>> addedKeys, @NotNull @NotNull Collection<LiveSupplier<ImmutableTableLocationKey>> removedKeys)

      Parameters:
      addedKeys - Collection of table location keys that were added.
      removedKeys - Collection of table location keys that were removed.
