[x3d-public] More Object Model Work: indicating nodes and statements for each profile within object model and X3DJSAIL

[John Carlson]

Don, is there anything in the object model for relationships between
profiles?   Thanks!

OK have taken the next step: added validation of profile and component
information for each node in the respective validate() methods.

Example excerpt from AnchorObject follows, where Anchor-specific values for
profiles/component/level get plugged in from entries in
X3DObjectModel-3.3.xml:

// profile validation test, if connected to full scene
if (findAncestorX3DObject() != null)
{
        String     modelProfile = findAncestorX3DObject().getProfile();
        headObject modelHead    = findAncestorX3DObject().getHead();
        ArrayList<componentObject> sceneComponentsList = new ArrayList<>();
        if (modelHead != null)
                sceneComponentsList = modelHead.getComponentList();
        boolean hasSatisfactoryComponent = false;
        for (componentObject nextComponent : sceneComponentsList)
        {
                if ( nextComponent.getName().equals("Networking") &&
                        (nextComponent.getLevel() >= 2))
                        hasSatisfactoryComponent = true;
        }
        if (!hasSatisfactoryComponent &&
                !modelProfile.equals("CADInterchange") &&
                !modelProfile.equals("Interactive") &&
                !modelProfile.equals("Immersive") &&
                !modelProfile.equals("MedicalInterchange") &&
                !modelProfile.equals("MPEG4Interactive") &&
                !modelProfile.equals("Full"))
        {
                String errorNotice =
ConfigurationProperties.ERROR_ILLEGAL_VALUE
+
                        ": invalid X3D profile='" +
getContainerFieldOverride() +
                        "' for parent X3D model, add element <componentInfo
name='Networking' level='2'/> or assignment " +
                        "' findAncestorX3DObject().getHea
d().addComponentInfo(\"Networking\").setLevel(2);";
                validationResult.append(errorNotice).append("\n");
                throw new InvalidFieldException(errorNotice); // report
error
        }
}

Tested satisfactorily on HelloWorldProgram.java which indeed self-diagnosed
itself to reveal a missing component entry for Layering level 1.

Test program runs satisfactorily, a few other quirks appear to be
adjusted/fixed.  Now running recently released Java JDK version "1.8.0_141".

Updates now uploading, autogeneration stylesheet changes and smoke tests
checked in, this new release should be available in about an hour.

        http://www.web3d.org/specifications/java/X3DJSAIL.html

Looking things over, will probably add class constants for minimum
COMPONENT and LEVEL later to simplify programmer access.


all the best, Don
