com.google.protobuf.ByteString

com.google.protobuf.HBaseZeroCopyByteString

所有已实现的接口:

Iterable<Byte>

@InterfaceAudience.Private
public final class HBaseZeroCopyByteString
extends com.google.protobuf.ByteString

Helper class to extract byte arrays from ByteString without copy.

Without this protobufs would force us to copy every single byte array out of the objects de-serialized from the wire (which already do one copy, on top of the copies the JVM does to go from kernel buffer to C buffer and from C buffer to JVM buffer).
