Not quite getting that Object-polymorphism thing ...

Objects. Encapsulation of related fields and operations to make it easier to reuse and work with code. Easy enough!

Polymorphism. The ability to have objects behave in the same manner, through inheritance, interface, etc. Gotcha.

Now let's give this Object-Polymorphism thing a try ...

if(obj instanceof MMSNode) {
MMSNode node = (MMSNode)obj;
attribs = node.getAttribs();
}
else if(obj instanceof MMSPhysComp) {
MMSPhysComp physComp = (MMSPhysComp)obj;
attribs = physComp.getAttribs();
}
else if(obj instanceof MMSLogComp) {
MMSLogComp logComp = (MMSLogComp)obj;
attribs = logComp.getAttribs();
}
else if (obj instanceof MMSPhysLink) {
MMSPhysLink physLink = (MMSPhysLink)obj;
attribs = physLink.getAttribs();
}

Awww yeah, looks good to me! Just call me Mr. Object Oriented!
