RenderingManager

• java.lang.Object

Fields Summary
protected ModelNode	node The associated ModelNode, the one for which RenderingManager tracks regions.
protected boolean	rTileDirty True when the rendering tile needs to be recomputed.
protected com.sun.perseus.j2d.Tile	rTile The node's current rendering bounds
protected com.sun.perseus.j2d.Tile	lastRenderedTile The node's most recent rendered tile.
protected com.sun.perseus.j2d.Tile	lrtCache A value cached so that we don't reallocate tiles all the time.

Constructors Summary
protected RenderingManager(ModelNode node) node the associated ModeNode this.node = node;

Methods Summary
protected void	clearLastRenderedTile() After calling this method, getLastRendered should always return null. lastRenderedTile = null;
protected final void	dirty() Marks the rendering as dirty, meaning that the rendering tile cached value cannot be reused, if any value has been cached. rTileDirty = true; node.modifyingNodeRendering();
protected com.sun.perseus.j2d.Tile	getLastRenderedTile() return the set node's last actual rendering. If this node's hasRendering method returns false, then this method should return null. return lastRenderedTile;
protected com.sun.perseus.j2d.Tile	getRenderingTile() return the bounding box, in screen coordinate, which encompasses the node's rendering. if (rTileDirty) { node.computeRenderingTile(rTile); rTileDirty = false; } return rTile;
protected void	rendered() Should be called by ModelNode implementations when they have just rendered so that the rendered area is captured in the lastRenderedTile. Important: it is the responsibility of the classes using this method to make sure the rendering tile is not dirty when calling this method. If the rendering tile is dirty, then the captured value will not correspond to the actual rendering area. if (lastRenderedTile == null) { lastRenderedTile = lrtCache; } lastRenderedTile.x = rTile.x; lastRenderedTile.y = rTile.y; lastRenderedTile.maxX = rTile.maxX; lastRenderedTile.maxY = rTile.maxY;
