方法详细资料

setNextBuffer

public void setNextBuffer(Buffer buffer)
                   throws IOException

指定者:

setNextBuffer 在接口中 RecordDeserializer<T extends org.apache.flink.core.io.IOReadableWritable>

抛出:

IOException

getUnconsumedBuffer

public org.apache.flink.util.CloseableIterator<Buffer> getUnconsumedBuffer()
                                                                    throws IOException

从接口复制的说明: RecordDeserializer

Gets the unconsumed buffer which needs to be persisted in unaligned checkpoint scenario.

Note that the unconsumed buffer might be null if the whole buffer was already consumed before and there are no partial length or data remained in the end of buffer.

指定者:

getUnconsumedBuffer 在接口中 RecordDeserializer<T extends org.apache.flink.core.io.IOReadableWritable>

抛出:

IOException

getNextRecord

public RecordDeserializer.DeserializationResult getNextRecord(T target)
                                                       throws IOException

指定者:

getNextRecord 在接口中 RecordDeserializer<T extends org.apache.flink.core.io.IOReadableWritable>

抛出:

IOException

clear

public void clear()

指定者:

clear 在接口中 RecordDeserializer<T extends org.apache.flink.core.io.IOReadableWritable>
