Class PROTORule  

java.lang.Object
  com.trapezium.vrml.grammar.PROTORule

---

public class PROTORule

extends java.lang.Object

Creates the scene graph component for a PROTO declaration. Grammar handled by "Build" method:

   proto ::=
        PROTO nodeTypeId [ interfaceDeclarations ] { protoBody } ;
           
   interfaceDeclarations ::=
        interfaceDeclaration |
        interfaceDeclaration interfaceDeclarations |
             empty ;

   protoBody ::=
        protoStatements node statements ;

   protoStatements ::=
        protoStatement |
        protoStatement protoStatements |
        empty ;
  

Note: the implementation of the "protoBody" portion of above grammar is done through the SceneRule, followed by a check that the body consists of at least one node. This check (and possible error mark) is done by the "setBuiltInNodeType" method.
