Class EObjectVisitor

java.lang.Object

com._1c.g5.v8.dt.core.model.EObjectVisitor

public class EObjectVisitor
extends Object

The EObject visitor.
It walks through the EObject.

     EObject eObject = ...;
     IEObjectVisitorCallback callback = ...;

     EObjectVisitor visitor = new EObjectVisitor(callback);
     visitor.visit(eObject);
 

For the specified eObject visit(EObject) performs the next steps:

• It delegates visiting to the callback: IEObjectVisitorCallback.visit(EObject);
• collects subordinate objects and recursively invokes 'visit' operation;
• delegates post visiting to the callback: IEObjectVisitorCallback.postVisit(EObject)

Subordinate objects are the children of the given one determined not only physically but logically (determined by business rules). Subordinate objects are collected by ISubordinateObjectsCollector.collectSubordinateObjects(EObject). If there are no collectors provided subordinate objects it will be automatically collected. It collects all containment references of the specified object in automatical way.
