Package PamView

Class HoverData

java.lang.Object

PamView.HoverData

public class HoverData
extends Object

Holds hover data. Added to a list in a GeneralProjector every time a display is drawn. Was initially used to quickly obtain hover information on the map display but is now also being used to identify data units enclosed within marks made on the display with the OverlayMark system.

HoverData

public HoverData()

HoverData

public HoverData(Shape drawnShape,
 PamDataUnit pamDataUnit,
 int iSide,
 int subPlotNumber)

public HoverData(Coordinate3d c,
 PamDataUnit pamDataUnit,
 int iSide,
 int subPlotNumber)

Method Details

getDataUnit

public PamDataUnit getDataUnit()

Get the data unit associated with the hover data.

Returns:

a pma data unit.

setTransformShape

public void setTransformShape(TransformShape shape2)

setAmbiguity

public void setAmbiguity(int iSide)

setDataUnit

public void setDataUnit(PamDataUnit pamDataUnit)

getDrawnShape

public Shape getDrawnShape()

Get the drawn shape

Returns:

drawn shape

setDrawnShape

public void setDrawnShape(Shape drawnShape)

Set the drawn shape

Parameters:

drawnShape -

distFromCentre

public double distFromCentre(double x,
 double y)

getShapeCentre

public Point2D getShapeCentre()

Get the centre of the drawn shape. This is actually the centre of the bounding rectangle, which may be different to any concept of a geometric centre for some shapes.

Returns:

shape centre.

setCoordinate3D

public void setCoordinate3D(Coordinate3d coordinate3d)

getAmbiguity

public int getAmbiguity()

Get the ambiguity of the hover data i.e. one data unit may have multiple shapes/co-ordinates e.g. localisations on the map

Returns:

the ambiguity (previously refferred to as iSide)

getTransfromShape

public TransformShape getTransfromShape()

Get the shape in whihc hover text is located. May be null if CoOrdintate3d used instead.

Returns:

the hover shape. Hover text is allowed inside the shape boundary.

getSubPlotNumber

public int getSubPlotNumber()

Returns:

the subPlotNumber

setSubPlotNumber

public void setSubPlotNumber(int subPlotNumber)

Parameters:

subPlotNumber - the subPlotNumber to set
