Class PBCosVisitor

java.lang.Object

org.verapdf.model.visitor.cos.pb.PBCosVisitor

All Implemented Interfaces:

org.apache.pdfbox.cos.ICOSVisitor

public final class PBCosVisitor
extends Object
implements org.apache.pdfbox.cos.ICOSVisitor

Implementation of ICOSVisitor which realize Visitor pattern. Current implementation create objects of abstract model implementation for corresponding objects of pdf box. Methods call from <? extends COSBase> objects using accept() method.
