Class ShapeVisitor

java.lang.Object

org.apache.poi.xdgf.usermodel.shape.ShapeVisitor

Direct Known Subclasses:

ShapeRenderer, ShapeTextVisitor

public abstract class ShapeVisitor
extends java.lang.Object

Used to iterate through shapes To change the behavior of a particular visitor, you can override either accept() or getAcceptor() [preferred] If accept() or visit() throw StopVisitingThisBranch, the iteration will not visit subshapes of the shape.
