示例1: readNext
import org.apache.samza.system.IncomingMessageEnvelope; //导入方法依赖的package包/类
public IncomingMessageEnvelope readNext() {
if (!hasNext()) {
LOG.warn("Attempting to read more data when there aren't any. ssp=" + systemStreamPartition);
return null;
}
// record the next offset before we read, so when the read fails and we reconnect,
// we seek to the same offset that we try below
curSingleFileOffset = curReader.nextOffset();
IncomingMessageEnvelope messageEnvelope = curReader.readNext();
// Copy everything except for the offset. Turn the single-file style offset into a multi-file one
return new IncomingMessageEnvelope(messageEnvelope.getSystemStreamPartition(), getCurOffset(),
messageEnvelope.getKey(), messageEnvelope.getMessage(), messageEnvelope.getSize());
}
示例2: checkEndOfStream
import org.apache.samza.system.IncomingMessageEnvelope; //导入方法依赖的package包/类
