Class PipelineResizingTransformer

java.lang.Object
  samples.preview_new_graphdraw.transform.PipelineResizingTransformer

All Implemented Interfaces:

LayoutTransformer

public class PipelineResizingTransformer
extends Object
implements LayoutTransformer

Changes an EmittedLayout from a fixed size to a new fixed size. Vertices are scaled directly.

Method Summary

void	adjustSize(Dimension d) Adjusts this transformer to be working in this size a space
Coordinates	invert(Coordinates in) This does the *reverse* of the trasformation, for a given point.
boolean	supportsInvert() Most functions should support invert.

public PipelineResizingTransformer()

Method Detail

transform

public EmittedLayout transform(EmittedLayout el)

Description copied from interface: LayoutTransformer

Transforms the given layout. May (but needn't) return the same layout object, albeit somewhat stomped-upon.

Specified by:

transform in interface LayoutTransformer

See Also:

LayoutTransformer.transform(samples.preview_new_graphdraw.EmittedLayout)

adjustSize

public void adjustSize(Dimension d)

Description copied from interface: LayoutTransformer

Adjusts this transformer to be working in this size a space

Specified by:

adjustSize in interface LayoutTransformer

See Also:

LayoutTransformer.adjustSize(java.awt.Dimension)

supportsInvert

public boolean supportsInvert()

Description copied from interface: LayoutTransformer

Most functions should support invert. If your layout transformer can't be inverted, this should return false. Note that having even one layout be un-invertible makes the whole pipeline un-invertble.

Specified by:

supportsInvert in interface LayoutTransformer

Returns:

true if the layout can be inverted.

See Also:

LayoutTransformer.supportsInvert()

invert

public Coordinates invert(Coordinates in)

Description copied from interface: LayoutTransformer

This does the *reverse* of the trasformation, for a given point. This should be quite fast, as it's done in interactive time (e.g. while a user is dragging around a vertex).

Specified by:

invert in interface LayoutTransformer

LayoutTransformer.invert(samples.preview_new_graphdraw.Coordinates)
