Description

Methods

Public procedure AssignArray( const AItemsArray: array of TVRMLNodeClass);
 
Public function IndexOf(NodeClass: TVRMLNodeClass): Integer; overload;
 
Public function IndexOf(Node: TVRMLNode): Integer; overload;

This is equivalent to IndexOf(NodeClass.ClassType), taking care of necessary typecasts.

Public function IndexOfAnyAncestor(Node: TVRMLNode): Integer;

This looks for a node class that is ancestor of given Node, in other words that satisfies Node is Items[Result]. So, comparing to IndexOf, this may also find something when IndexOf doesn't, since this doesn't require an exact match — only "is" match.

Returns -1 if not found.

Public procedure Add(Value: TVRMLNodeClass);
 
Public procedure AddRegisteredImplementing(Interf: TGUID);

Add all node classes registered in NodesManager that implement given interface Interf.

Properties
