方法详细资料

getDataChannel

StateMachine.DataChannel getDataChannel()

返回:

a channel for streaming state machine data.

cleanUp

CompletableFuture<?> cleanUp()

Clean up asynchronously this stream. When there is an error, this method is invoked to clean up the associated resources. If this stream is not yet linked (see DataApi#link(DataStream, LogEntryProto)), the state machine may choose to remove the data or to keep the data internally for future recovery. If this stream is already linked, the data must not be removed.

返回:

a future for the cleanup task.

getExecutor

default Executor getExecutor()

返回:

an Executor for executing the streaming tasks of this stream. If the returned value is null, the default Executor will be used.
