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 org.apache.flink.core.io.InputStatus processInput()
                                                  throws Exception

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().

指定者:

close 在接口中 Closeable

指定者:

close 在接口中 AutoCloseable

抛出:

IOException

prepareSnapshot
