ElementLayout

public ElementLayout()

Constructs a new and empty ElementLayout.

Method Detail

getBounds2D

public java.awt.geom.Rectangle2D.Float getBounds2D(java.awt.geom.Rectangle2D.Float out)

Returns the bounds of this layout in float precision.

Parameters:

out - The same as the return parameter, not null.

Returns:

The bounds of this layout.

addToBounds

public void addToBounds(float x,
                        float y)

Adds an arbitrary point to the bounds of this layout.

Parameters:

x - The x-coordinate of the point.

y - The y-coordinate ot the point.

addToBounds

public void addToBounds(java.awt.geom.Rectangle2D.Float bounds)

Adds an arbitrary rectangle to the bounds of this layout.

Parameters:

bounds - An arbitrary rectangle, not null.

addElement

public void addElement(Element element)

Adds a new element with no translation to this layout.

Parameters:

element - The element to be added, not null.

addElement

public void addElement(Element element,
                       float translateX,
                       float translateY)

Adds a new element with the given translation to this layout.

Parameters:

element - The element to be added, not null.

translateX - The translation of the element in x-direction.

translateY - The translation of the element in y-direction.

getBounds

public java.awt.Rectangle getBounds()

Description copied from interface: Layout

Returns the bounds of this layout. The bounds may lay somewhere in the coordinate system, even in negative areas.

Specified by:

getBounds in interface Layout

Returns:

The bounds of this layout, never null.

paint

public void paint(java.awt.Graphics g)

Description copied from interface: Layout

Paints this layout to the given graphics.

Specified by:

paint in interface Layout

Parameters:

g - The target graphics object.

getLogicalPoint

public LogicalPoint getLogicalPoint(java.awt.Point p)

Description copied from interface: Layout

Returns a logic point for a given physcal point. The logic point carries information about the underlying data model and the current indices of the model. This method is used to display for example a tooltip at the position of the mouse cursor or to implement a drill down mechanism.

Specified by:

getLogicalPoint in interface Layout

Parameters:

p - The point relative to the coordinate system of this layout.

Returns:

A logic point or null if the given point is not inside a shape.

getElements

public ElementIterator getElements()

Description copied from interface: IteratableLayout

Returns an element iterator that provides a flat view to all the elements in this layout.

Specified by:

getElements in interface IteratableLayout

Returns:

The element iterator, never null.
