Class RwiVisitorAdapter

public class RwiVisitorAdapter

implements RwiVisitor

RwiVisitorAdapter class extends RwiVisitor functionality by
providing two additional methods visitContainer and visitElement.

These methods are used to perform the same actions for all kinds of containers or elements.
For example, the visitContainer method performs the same action for any container
(which can be node, diagram or package), while visitNode method perfoms
a special action for a node, which can be different from the action required for a diagram or a package:

public class CoolVisitor extends RwiVisitorAdapter{

public Object visitNode(RwiNode node){

IdeMessageManagerAccess.printMessage(IdeMessageType.INFORMATION, "An action for RwiNode."); // specific  action for a node

return visitContainer(node);  //the same action for all kinds of containers

}

public Object visitPackage(RwiPackage rwiPackage){

IdeMessageManagerAccess.printMessage(IdeMessageType.INFORMATION, "An action for RwiPackage.");  // specific  action for a package

return null; // for example, let's suppose for packages we do not need any additional actions;

}

public Object visitContainer(RwiContainer container){

IdeMessageManagerAccess.printMessage(IdeMessageType.INFORMATION, "An action for all RwiContainers.");

return visitElement(container);  //the same action for all kinds of elements

}

public Object visitElement(RwiElement element){

IdeMessageManagerAccess.printMessage(IdeMessageType.INFORMATION, "An action for all RwiElements.");

return null;

}

//since visitor methods for diagrams, members and links are not overridden, they will call visitContainer method (see below)

}

 

In this class methods do nothing, here are the bodies of methods:

public Object visitNode(RwiNode node){ return visitContainer(node); }

public Object visitMember(RwiMember member){ return visitElement(member); }

public Object visitContainer(RwiContainer container){ return visitElement(container); }

public Object visitPackage(RwiPackage rwiPackage){ return visitContainer(rwiPackage); }

public Object visitDiagram(RwiDiagram diagram){ return visitContainer(diagram); }

public Object visitLink(RwiLink link){ return visitElement(link); }

public Object visitElement(RwiElement element){ return null; }
