Class LowCopyProtobufOutput

java.lang.Object
io.protostuff.LowCopyProtobufOutput
All Implemented Interfaces:
Output

public final class LowCopyProtobufOutput extends Object implements Output
Output that differs from the standard by attempting to avoid extra copies of large ByteBuffer fields. When used with ByteBuffer=true compiler option, we can splice in ByteBuffer objects without copying them. Most of the magic lives in LinkBuffer, so this class exists just to serialize to a LinkBuffer.
