supportsOpaqueRegions

protected boolean supportsOpaqueRegions()

Description copied from class: NGNode

Gets whether this NGNode supports opaque regions at all. Most node types do not, but some do. If an NGNode subclass is written to support opaque regions, it must override this method to return true. The subclass must then also override the computeDirtyRegion method to return the dirty region, or null if the node in its current state doesn't have one. This method is intended to be immutable.

Overrides:

supportsOpaqueRegions in class NGNode

Returns:

Whether this NGNode implementation supports opaque regions. This could also have been implemented via an interface that some NGNodes implemented, but then we'd have instanceof checks which I'd rather avoid.

hasOpaqueRegion

protected boolean hasOpaqueRegion()

Description copied from class: NGNode

Called only on NGNode subclasses which override NGNode.supportsOpaqueRegions() to return true, this method will return whether or not this NGNode is in a state where it has an opaque region to actually return. If this method returns true, a subsequent call to NGNode.computeOpaqueRegion(com.sun.javafx.geom.RectBounds) must return a non-null result. Any state used in the computation of this method, when it changes, must result in a call to NGNode.invalidateOpaqueRegion().

Overrides:

hasOpaqueRegion in class NGShape

Returns:

Whether this NGNode currently has an opaque region.

computeOpaqueRegion

protected RectBounds computeOpaqueRegion(RectBounds opaqueRegion)

Description copied from class: NGNode

Computes and returns the opaque region for this node. This method

Overrides:

computeOpaqueRegion in class NGNode

Returns:

isRounded

boolean isRounded()

renderEffect

protected void renderEffect(Graphics g)

Overrides:

renderEffect in class NGNode

renderEffectDirectly

private boolean renderEffectDirectly(Graphics g)

getShape

public final Shape getShape()

Specified by:

getShape in class NGShape

createShapeRep

protected ShapeRep createShapeRep(Graphics g)

Overrides:

createShapeRep in class NGShape

hasRightAngleMiterAndNoDashes

private static boolean hasRightAngleMiterAndNoDashes(BasicStroke bs)

rectContains

static boolean rectContains(float x,
                            float y,
                            NGShape node,
                            RectangularShape r)

isRectClip

protected final boolean isRectClip(BaseTransform xform,
                                   boolean permitRoundedRectangle)

Returns whether a clip represented by this node can be rendered using axis aligned rect clip. The return value depends on whether the rectangle has arcs, current rendering mode (stroked or not), and whether the transform is only translate or scale or something more complex.

Overrides:

isRectClip in class NGNode

Returns:

whether this rectangle is axis aligned when rendered given node's and rendering transform
