Interfacepublic interface INodeOperation

Interface for node operations.

Implements the visitor design pattern: Using the visitor design pattern, you can define a new operation on Node and its subclasses without having to change the classes and without having to take care of traversing the node tree.


Example 
      var mySpecialOperation:SpecialOperation = new SpecialOperation;
  
      mySpecialOperation.someParameter = 0.8;
      someTreeNode.perform(mySpecialOperation);
      trace(mySpecialOperation.someResult);
  
      mySpecialOperation.someParameter = 0.2;
      someOtherTreeNode.perform(mySpecialOperation);
      trace(mySpecialOperation.someResult);
