com.trapezium.chisel.cleaners
Class IFS_NoFaceRemover  

java.lang.Object
  com.trapezium.chisel.Optimizer
      com.trapezium.chisel.cleaners.IFS_NoFaceRemover

All Implemented Interfaces:

java.util.EventListener, com.trapezium.chisel.NodeLocatorListener, com.trapezium.chisel.OptionHolder

---

public class IFS_NoFaceRemover

extends com.trapezium.chisel.Optimizer

This removes IndexedFaceSets that have no faces, unless the IFS has a DEF that is used.

(package private)  void	checkUSE(com.trapezium.vrml.fields.Field f)           Check if a Node field is a USE node, and is USEing a DEF being removed.

public IFS_NoFaceRemover()

Method Detail

reset

public void reset()

Description copied from class: com.trapezium.chisel.Optimizer

reset optimizer, subclasses may need this

---

attemptOptimization

public void attemptOptimization(com.trapezium.vrml.node.Node n)

Description copied from class: com.trapezium.chisel.Optimizer

template, subclasses override this if they modify Nodes

---

checkUSE

void checkUSE(com.trapezium.vrml.fields.Field f)

Check if a Node field is a USE node, and is USEing a DEF being removed. If it is, then that USE node gets converted into the removed DEF.

---

checkReplace

void checkReplace(com.trapezium.vrml.node.DEFUSENode dun,
                  com.trapezium.vrml.node.Node n)

Replace a USE node with the corresponding DEF on first USE encountered, but only do this if the USE node is within an area that is being removed.

---

optimize

public void optimize(com.trapezium.chisel.TokenPrinter tp,
                     java.lang.Object param,
                     int startTokenOffset,
                     int endTokenOffset)

Two possibilities here, if the param is null, we are removing the VrmlElement, so we just count the removal and do nothing. If the param is a Node, it means that we have previously removed the DEF for a USE node, so the USE node is transformed into the original DEF.

---

summarize

public void summarize(java.io.PrintStream ps)

Description copied from class: com.trapezium.chisel.Optimizer

default summary (none), used by command line version
