Deprecated Interfaces

Interface and Description
org.apache.flink.streaming.api.checkpoint.Checkpointed Please use ListCheckpointed as illustrated above, or CheckpointedFunction for more control over the checkpointing process.
org.apache.flink.streaming.api.checkpoint.CheckpointedAsynchronously Please use ListCheckpointed and CheckpointedFunction instead, as illustrated in the example above.
org.apache.flink.streaming.api.checkpoint.CheckpointedRestoring Please use CheckpointedFunction or ListCheckpointed after restoring your legacy state.
