Class CommandQuery

java.lang.Object
  org.limitless.nmc.Prototype1.CommandQuery

All Implemented Interfaces:

Command, StorageVisitor

public class CommandQuery
extends java.lang.Object
implements Command, StorageVisitor

This is a mechanism to list all relations (and the objects they connect) based on query conditions. The complexity of this query will increase as we learn more what sorts of things we'd like to know. This is highly subject to change! See 5.1.2.7 in the prototype_1.html document.
