                               BoundedMultiInput endOfInputAware)

方法详细资料

getAvailableFuture

public CompletableFuture<?> getAvailableFuture()

指定者:

getAvailableFuture 在接口中 org.apache.flink.runtime.io.AvailabilityProvider

processInput

public DataInputStatus processInput()
                             throws Exception

从接口复制的说明: StreamInputProcessor

In case of two and more input processors this method must call InputSelectable.nextSelection() to choose which input to consume from next.

指定者:

processInput 在接口中 StreamInputProcessor

返回:

input status to estimate whether more records can be processed immediately or not. If there are no more records available at the moment and the caller should check finished state and/or AvailabilityProvider.getAvailableFuture().

抛出:

Exception

prepareSnapshot

public CompletableFuture<Void> prepareSnapshot(org.apache.flink.runtime.checkpoint.channel.ChannelStateWriter channelStateWriter,
                                               long checkpointId)
                                        throws org.apache.flink.runtime.checkpoint.CheckpointException

指定者:

prepareSnapshot 在接口中 StreamInputProcessor

抛出:

org.apache.flink.runtime.checkpoint.CheckpointException

close

public void close()
           throws IOException

指定者:

close 在接口中 Closeable

指定者:

close 在接口中 AutoCloseable

抛出:

IOException
