MultipleRecordWriters

public MultipleRecordWriters(List<RecordWriter<T>> recordWriters)

方法详细资料

broadcastEvent

public void broadcastEvent(AbstractEvent event)
                    throws IOException

从接口复制的说明: RecordWriterDelegate

Broadcasts the provided event to all the internal record writer instances.

指定者:

broadcastEvent 在接口中 RecordWriterDelegate<T extends org.apache.flink.core.io.IOReadableWritable>

参数:

event - the event to be emitted to all the output channels.

抛出:

IOException

getRecordWriter

public RecordWriter<T> getRecordWriter(int outputIndex)

从接口复制的说明: RecordWriterDelegate

Returns the internal actual record writer instance based on the output index.

指定者:

getRecordWriter 在接口中 RecordWriterDelegate<T extends org.apache.flink.core.io.IOReadableWritable>

参数:

outputIndex - the index respective to the record writer instance.

getAvailableFuture

public CompletableFuture<?> getAvailableFuture()

指定者:

getAvailableFuture 在接口中 AvailabilityProvider

返回:

a future that is completed if the respective provider is available.

isAvailable

public boolean isAvailable()

从接口复制的说明: AvailabilityProvider

In order to best-effort avoid volatile access in CompletableFuture.isDone(), we check the condition of future == AVAILABLE firstly for getting probable performance benefits while hot looping.

It is always safe to use this method in performance nonsensitive scenarios to get the precise state.

指定者:

isAvailable 在接口中 AvailabilityProvider

返回:

true if this instance is available for further processing.

close

public void close()

指定者:

close 在接口中 AutoCloseable
