public class SEScalingModel
extends SEInterpolatedModel
implements SEScalableNode

A scaling_model node. This scales other features, with the anchor of the scaling operation specified by an absolute x,y point.

accept

public void accept(SEShowVisitor visitor)

Description copied from interface: SENode

Calls the visit method corresponding to this node type.

If you are defining a user-defined feature, there are some restrictions that you'll want to follow. If your extension is a feature that has children, then you should make it a subclass of one of the built-in feature types, Assembly, Modifer or Group. That's because the GRIN compiler defines visitors that need to visit every node in the tree, but these built-in visitors don't know about your extension types. By making your extension type a subclass of one of the standard ones, and by making your accept() method call either visitAssembly(), visitGroup() or visitUserDefinedModifier(), as appropriate, you'll ensure that all the children get visited.

Specified by:

accept in interface SENode

Overrides:

accept in class SEInterpolatedModel

Parameters:

visitor - SEShowVisitor object.

scaleBy

public void scaleBy(int xScale,
                    int yScale,
                    int xOffset,
                    int yOffset)

Scale this node by the given scale factor, and apply the given offset. This will change the size of the features and RC handlers within the show at compile time, so no special scaling action is required at runtime.

Specified by:

scaleBy in interface SEScalableNode

Parameters:

xScale - x scale factor in mills

yScale - y scale factor in mills

xOffset - x offset in pixels

yOffset - y offset in pixels

toString

public java.lang.String toString()

Overrides:

toString in class SEInterpolatedModel

Returns:

a developer-friendly description of this feature, for debugging
