Class WireFormat

java.lang.Object

com.google.protobuf.WireFormat

public final class WireFormat
extends java.lang.Object

This class is used internally by the Protocol Buffer library and generated message implementations. It is public only because those generated messages do not reside in the protobuf package. Others should not use this class directly.

This class contains constants and helper functions useful for dealing with the Protocol Buffer wire format.
