TextProxy

public class TextProxy extends StructureNodeProxy
A TextProxy proxies a Text node and computes its expanded content from the proxied text's data content.

Fields Summary
protected RenderingManager
renderingManager
Used to track the node's rendering area and the rendered areas.
protected GlyphLayout
firstChunk
Points to the first text chunk.
protected GlyphLayout
lastChunk
Points to the last text chunk.
Constructors Summary
public TextProxy(Text proxiedText)

param
proxiedText Text node to proxy.

        super(proxiedText);
        if (DirtyAreaManager.ON) {
            renderingManager = new RenderingManager(this);
        }
Methods Summary
com.sun.perseus.j2d.BoxaddNodeBBox(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,

        checkLayout();
        return ((Text) proxied).addNodeBBox(bbox, t, firstChunk);
voidcheckLayout()
Checks that the text's layout has been computed and computes it in case it was not.

        if (firstChunk == null) {
            firstChunk = ((Text) proxied).layoutText(this);
            GlyphLayout cur = firstChunk;
            while (cur.nextSibling != null) {
                cur = cur.nextSibling;
            }
            lastChunk = (GlyphLayout) cur;
        }
public voidclearLayouts()
Clears the node's layout cache. For ElementNodeProxy, we just reset the node so that expanded content be computed again and we request the proxied node to also clear its layout cache. This is to ensure that Font Data Base changes are covered.

        modifyingNode();
        clearLayoutsQuiet();
        super.clearLayouts();
        modifiedNode();
public voidclearLayoutsQuiet()
Clears all cached layout information but does not generate modification events for this node.

        firstChunk = null;
        lastChunk = null;
protected voidcomputeRenderingTile(com.sun.perseus.j2d.Tile tile)
This method is overridden for elements which has special renderings, such as the ShapeNodes.

param
tile the Tile instance whose bounds should be set.

        checkLayout();
        ((Text) proxied).computeRenderingTile(tile, txf, this, firstChunk);

return
the tight bounding box in current user coordinate space.

        return addNodeBBox(null, null);

return
true

        return true;

                rg.getRenderingTile().isHit(primitiveTile)) {
                // rg.setPrimitiveTile(primitiveTile);
                ((Text) proxied).paintRendered(rg, this, txf, firstChunk);

                // 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();
            }
