Set the object this glyph represents in the client application. The owner can be any arbitrary Java object set by the client application, that the programmer wants to be easily accessible through the Glyph (typically the owner will be an object that models a logical concept of which a visual depiction is given by the glyph). Multiple glyphs can have the same owner. A glyph can only have one owner.

Parameters:

t - provided by client application, null by default.

public boolean visibleInRegion(double wb,
                               double nb,
                               double eb,
                               double sb,
                               int i)

Method used internally to find out if it is necessary to project and draw this glyph for a given camera.

Parameters:

wb - west region boundary (virtual space coordinates)

nb - north region boundary (virtual space coordinates)

eb - east region boundary (virtual space coordinates)

sb - south region boundary (virtual space coordinates)

i - camera index (useuful only for some glyph classes redefining this method)

Returns:

true if the glyph is currently visible in the region delimited by wb, nb, eb, sb, symbolising the region seen through a camera

visibleInViewport

public boolean visibleInViewport(double wb,
                                 double nb,
                                 double eb,
                                 double sb,
                                 Camera c)

containedInRegion

public boolean containedInRegion(double wb,
                                 double nb,
                                 double eb,
                                 double sb,
                                 int i)

Method used internally to find out if it is necessary to project and draw the glyph through a lens for a given camera.

Parameters:

wb - west region boundary (virtual space coordinates)

nb - north region boundary (virtual space coordinates)

eb - east region boundary (virtual space coordinates)

sb - south region boundary (virtual space coordinates)

i - camera index (useuful only for some glyph classes redefining this method)

Returns:

true if the glyph intersects the region delimited by wb, nb, eb, sb

fillsView

public abstract boolean fillsView(double w,
                                  double h,
                                  int camIndex)

Find out if this glyph completely fills a view. (In which case it is not necessary to repaint objects below it in the drawing stack). If implemented, this method should be very efficient, as it is used by an optional top-down clipping algorithm. Otherwise it might cost more time than it can potentially save. Until now it has only been implemented for non-reorientable rectangles and was activated only for treemap-like representations in which a lot of rectangles can potentially overlap each other.

visibleInDisc

public boolean visibleInDisc(double dvx,
                             double dvy,
                             double dvr,
                             Shape dvs,
                             int camIndex,
                             int jpx,
                             int jpy,
                             int dpr)

Find out if a glyph is visible in a circular area. Not implemented yet for most glyph classes. Used for instance to implement DynaSpot picking.

getBounds

public double[] getBounds()

Get the bounding box of this Glyph in virtual space coordinates.

Returns:

west, north, east and south bounds in virtual space.

stickToGlyph

public static void stickToGlyph(Glyph g1,
                                Glyph g2)

Stick glyph g1 to glyph g2. Behaves like a one-way constraint.

unstickFromGlyph

public static void unstickFromGlyph(Glyph g1,
                                    Glyph g2)

Unstick glyph g1 from glyph g2.

unstickAllGlyphs

public static void unstickAllGlyphs(Glyph g)

Unstick all glyphs sticked to Glyph g.

getJava2DShape

public abstract Shape getJava2DShape()

Get the Java2D Shape corresponding to this Glyph. Virtual Space coordinates.

clone
