org.apache.hadoop.hbase.procedure2.util.ByteSlot

所有已实现的接口:

Closeable, Flushable, AutoCloseable

@InterfaceAudience.Private
@InterfaceStability.Evolving
public class ByteSlot
extends OutputStream

Similar to the ByteArrayOutputStream, with the exception that we can prepend an header. e.g. you write some data and you want to prepend an header that contains the data len or cksum. ByteSlot slot = new ByteSlot(); // write data slot.write(...); slot.write(...); // write header with the size of the written data slot.markHead(); slot.write(Bytes.toBytes(slot.size())); // flush to stream as [header, data] slot.writeTo(stream);
