AbstractRenderingNodeProxy

• java.lang.Object
  • CompositeGraphicsNodeProxy

Fields Summary
protected RenderingManager	renderingManager Used to track the node's rendering area and the rendered areas.

Constructors Summary
protected AbstractRenderingNodeProxy(AbstractRenderingNode proxiedNode) param proxiedNode AbstractRenderingNode to proxy super(proxiedNode); if (DirtyAreaManager.ON) { renderingManager = new RenderingManager(this); }

Methods Summary
com.sun.perseus.j2d.Box	addBBox(com.sun.perseus.j2d.Box bbox, com.sun.perseus.j2d.Transform t) param bbox the bounding box to which this node's bounding box should be appended. That bounding box is in the target coordinate space. It may be null, in which case this node should create a new one. param t the transform to apply from the node's coordinate space to the target coordinate space. May be null for the identity transform. return the node's bounding box in the target coordinate space. return addNodeBBox(bbox, t);
com.sun.perseus.j2d.Box	addNodeBBox(com.sun.perseus.j2d.Box bbox, com.sun.perseus.j2d.Transform t) param bbox the bounding box to which this node's bounding box should be appended. That bounding box is in the target coordinate space. It may be null, in which case this node should create a new one. param t the transform from the node coordinate system to the coordinate system into which the bounds should be computed. return the bounding box of this node, in the target coordinate space, return proxied.addNodeBBox(bbox, t);
protected void	clearLastRenderedTile() After calling this method, getLastRenderedTile should always return null. renderingManager.clearLastRenderedTile();
protected void	clearLayouts() Clears the text layouts, if any exist. This is typically called when the font selection has changed and nodes such as Text should recompute their layouts. This should recursively call clearLayouts on children node or expanded content, if any.
protected final void	computeRenderingTile(com.sun.perseus.j2d.Tile tile) Computes this node's rendering tile. param tile the Tile instance whose bounds should be set. return the device space rendering tile. ((AbstractRenderingNode) proxied).computeRenderingTile(tile, txf, this);
public org.w3c.dom.svg.SVGRect	getBBox() return the tight bounding box in current user coordinate space. return addNodeBBox(null, null);
protected com.sun.perseus.j2d.Tile	getLastRenderedTile() return the tile which encompasses the node's last actual rendering. return renderingManager.getLastRenderedTile();
protected final com.sun.perseus.j2d.Tile	getRenderingTile() return the bounding box, in screen coordinate, which encompasses the node's rendering. return renderingManager.getRenderingTile();
public boolean	hasNodeRendering() An AbstractNodeRendering has something to render. return true return true;
public void	modifyingProxied() Proxied nodes should call this method when they are being modified. super.modifyingProxied(); renderingDirty();
void	nodeHookedInDocumentTree() To be overriddent by derived classes, such as TimedElementNode, if they need to do special operations when hooked into the document tree. renderingDirty();
protected void	nodeRendered() Simply notifies the RenderingManager. if (DirtyAreaManager.ON) { renderingManager.rendered(); }
void	nodeUnhookedFromDocumentTree() To be overriddent by derived classes, such as TimedElementNode, if they need to do special operations when unhooked from the document tree. renderingDirty();
public void	paint(com.sun.perseus.j2d.RenderGraphics rg) Paints this node into the input RenderGraphics. param rg the RenderGraphics where the node should paint itself if (canRenderState != 0) { return; } if (DirtyAreaManager.ON) { Tile primitiveTile = getRenderingTile(); if (primitiveTile == null || rg.getRenderingTile().isHit(primitiveTile)) { // rg.setPrimitiveTile(primitiveTile); ((AbstractRenderingNode) proxied).paintRendered(rg, this, this, txf); // nodeRendered is called seperately from paintRendered // because paintRendered is used in different contexts, // for example by proxy nodes to render, using their // proxied node's paintRendered method. nodeRendered(); } } else { ((AbstractRenderingNode) proxied).paintRendered(rg, this, this, txf); }
protected void	recomputeTransformState(com.sun.perseus.j2d.Transform parentTransform) Recomputes the transform cache, if one exists. param parentTransform the Transform applied to this node's parent. super.recomputeTransformState(parentTransform); renderingDirty();
final void	renderingDirty() Should be called whenever this node's rendering becomes dirty. if (DirtyAreaManager.ON) { renderingManager.dirty(); }
public void	setDisplay(boolean newDisplay) param newDisplay the new computed display value super.setDisplay(newDisplay); renderingDirty();
protected void	setProxied(ElementNode newProxied) Modifies the node proxied by this proxy. param newProxied this node's new proxied node if (this.proxied == newProxied) { return; } super.setProxied(newProxied); renderingDirty();
public void	setVisibility(boolean newVisibility) param newVisibility the new computed visibility property. super.setVisibility(newVisibility); renderingDirty();
