public static void setNamespaceResolver(Namespace namespace,

---------------------------------------------------------------------- Tcl_SetNamespaceResolvers -> setNamespaceResolver Sets the command/variable resolution object for a namespace, thereby changing the way that command/variable names are interpreted. This allows extension writers to support different name resolution schemes, such as those for object-oriented packages. Command resolution is handled by the following method: resolveCmd (Interp interp, String name, Namespace context, int flags) throws TclException; Whenever a command is executed or Namespace.findCommand is invoked within the namespace, this method is called to resolve the command name. If this method is able to resolve the name, it should return the corresponding WrappedCommand. Otherwise, the procedure can return null, and the command will be treated under the usual name resolution rules. Or, it can throw a TclException, and the command will be considered invalid. Variable resolution is handled by the following method: resolveVar (Interp interp, String name, Namespace context, int flags) throws TclException; If this method is able to resolve the name, it should return the variable as Var object. The method may also return null, and the variable will be treated under the usual name resolution rules. Or, it can throw a TclException, and the variable will be considered invalid. Results: See above. Side effects: None. ----------------------------------------------------------------------
