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
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.

Field Summary
`protected ShapeVisitorAcceptor`	`_acceptor`

Constructor Summary
`ShapeVisitor()`

Method Summary
`boolean`	`accept(XDGFShape shape)`
`protected ShapeVisitorAcceptor`	`getAcceptor()` Is only called on construction of the visitor, allows mixing visitors and acceptors
`void`	`setAcceptor(ShapeVisitorAcceptor acceptor)`
`abstract void`	`visit(XDGFShape shape, java.awt.geom.AffineTransform globalTransform, int level)`
