  com.sun.opengl.util.packrect.Level

public class Level
extends Object

Constructor Summary

Level(int width, int height, int yPos, LevelSet holder)

Method Summary

boolean	add(Rect rect) Tries to add the given rectangle to this level only allowing non-disruptive changes like trivial expansion of the last level in the RectanglePacker and allocation from the free list.
void	compact(Object backingStore, BackingStoreManager manager)
boolean	couldAllocateIfCompacted(Rect rect) Indicates whether this Level could satisfy an allocation request if it were compacted.
void	dumpFreeSpace()
int	h()
boolean	isEmpty() Indicates whether this Level contains no rectangles.
Iterator	iterator()
boolean	remove(Rect rect) Removes the given Rect from this Level.
void	updateRectangleReferences() Updates the references to the Rect objects in this Level with the "next locations" of those Rects.
void	visit(RectVisitor visitor) Visits all Rects contained in this Level.
int	w()
int	yPos()

Constructor Detail

Level

public Level(int width,
             int height,
             int yPos,
             LevelSet holder)

Method Detail

w

public int w()

h

public int h()

yPos

public int yPos()

add

public boolean add(Rect rect)

Tries to add the given rectangle to this level only allowing non-disruptive changes like trivial expansion of the last level in the RectanglePacker and allocation from the free list. More disruptive changes like compaction of the level must be requested explicitly.

remove

public boolean remove(Rect rect)

Removes the given Rect from this Level.

isEmpty

public boolean isEmpty()

Indicates whether this Level contains no rectangles.

couldAllocateIfCompacted

public boolean couldAllocateIfCompacted(Rect rect)

Indicates whether this Level could satisfy an allocation request if it were compacted.

compact

public void compact(Object backingStore,
                    BackingStoreManager manager)

iterator

public Iterator iterator()

visit

public void visit(RectVisitor visitor)

Visits all Rects contained in this Level.

updateRectangleReferences

public void updateRectangleReferences()

Updates the references to the Rect objects in this Level with the "next locations" of those Rects. This is actually used to update the new Rects in a newly laid-out LevelSet with the original Rects.

dumpFreeSpace

public void dumpFreeSpace()
