   public BuiltinProtocol() 

Default constructor

   boolean builtin() 

Override Protocol's builtin to flag this class as a builtin.

Overrides:

builtin in class Protocol

   protected void addCapsule(String name, 
                             String version)  throws Exception

Builtin protocols must use this version of addCapsule. This versions uses the given version string to generate the MD5 hash for the code ID. (Thus, the version of a builtin protocol is not tied to the actual code.)

Each builtin protocol class has a version string associated with it. See, for example, DataCapsule.

See Also: VERSION

   protected void addCapsule(String name)  throws Exception

Builtin protocols should never call this version of addCapsule.

Overrides:

addCapsule in class Protocol
