Constructor Detail

QuadTreeCompositeFigure

public QuadTreeCompositeFigure()

Creates a new instance.

Method Detail

createFigureHandler

protected QuadTreeCompositeFigure.FigureHandler createFigureHandler()

indexOf

public int indexOf(Figure figure)

Description copied from interface: CompositeFigure

Returns the index of the specified child.

This is a convenience method for calling getChildren().indexOf(index);.

Specified by:

indexOf in interface CompositeFigure

Overrides:

indexOf in class AbstractCompositeFigure

Returns:

The index of the child, or -1 if the specified figure is not a child of this CompositeFigure.

basicAdd

public void basicAdd(int index,
                     Figure figure)

Description copied from interface: CompositeFigure

Adds a child to the figure at the specified index without firing events.

This method can be used to reinsert a child figure which has been temporarily removed from this CompositeFigure (for example to reorder the sequence of the children) and to efficiently build a drawing from an InputFormat.

Specified by:

basicAdd in interface CompositeFigure

Overrides:

basicAdd in class AbstractCompositeFigure

basicRemoveChild

public Figure basicRemoveChild(int index)

Description copied from interface: CompositeFigure

Removes the child at the specified index without firing events.

This method can be used to temporarily remove a child from this CompositeFigure (for example to reorder the sequence of the children).

Returns the removed child figure.

Specified by:

basicRemoveChild in interface CompositeFigure

Overrides:

basicRemoveChild in class AbstractCompositeFigure

draw

public void draw(java.awt.Graphics2D g)

Description copied from interface: Figure

Draws the figure.

Specified by:

draw in interface Figure

Overrides:

draw in class AbstractCompositeFigure

Parameters:

g - The Graphics2D to draw to.

sort

public java.util.List<Figure> sort(java.util.Collection<Figure> c)

Implementation note: Sorting can not be done for orphaned children.

draw

public void draw(java.awt.Graphics2D g,
                 java.util.Collection<Figure> c)

getFigures

public java.util.List<Figure> getFigures(java.awt.geom.Rectangle2D.Double bounds)

getChildren

public java.util.List<Figure> getChildren()

Description copied from interface: CompositeFigure

Returns an unchangeable list view on the children.

Specified by:

getChildren in interface CompositeFigure

Overrides:

getChildren in class AbstractCompositeFigure

findFigureInside

public Figure findFigureInside(java.awt.geom.Point2D.Double p)

Description copied from interface: Figure

Returns the figure that contains the given point.

Specified by:

findFigureInside in interface Figure

Overrides:

findFigureInside in class AbstractCompositeFigure

getFiguresFrontToBack

public java.util.List<Figure> getFiguresFrontToBack()

Returns an iterator to iterate in Z-order front to back over the children.

findFigure

public Figure findFigure(java.awt.geom.Point2D.Double p)

findFigureExcept

public Figure findFigureExcept(java.awt.geom.Point2D.Double p,
                               Figure ignore)

findFigureExcept

public Figure findFigureExcept(java.awt.geom.Point2D.Double p,
                               java.util.Collection ignore)

findFigureBehind

public Figure findFigureBehind(java.awt.geom.Point2D.Double p,
                               Figure figure)

findFigureBehind

public Figure findFigureBehind(java.awt.geom.Point2D.Double p,
                               java.util.Collection<Figure> figures)

Description copied from class: AbstractCompositeFigure

Sends a figure to the back of the composite figure.

Overrides:

sendToBack in class AbstractCompositeFigure

Parameters:

contains

public boolean contains(Figure f)

Description copied from interface: CompositeFigure
