Method Summary

boolean	elementContains(java.lang.Object element, java.awt.geom.Point2D point) Tests if the given element contains the given point.
boolean	elementIntersects(java.lang.Object element, java.awt.geom.Rectangle2D rectangle) Tests if the given element intersects with the given rectangle.
java.awt.Rectangle	getElementBounds(java.lang.Object element) Gets the bounding box for the element.
java.awt.geom.Rectangle2D	getElementBounds2D(java.lang.Object element) Return the high precision bounding box of the element.
void	paintDrawingElement(java.awt.Graphics graphics, java.lang.Object element) Paints the given element.

Method Detail

paintDrawingElement

public void paintDrawingElement(java.awt.Graphics graphics,
                                java.lang.Object element)

Paints the given element.

Parameters:

graphics - graphics context to use for painting

element - element to be painted

getElementBounds

public java.awt.Rectangle getElementBounds(java.lang.Object element)

Gets the bounding box for the element. If the element is unbounded then this method returns null.

Parameters:

element - element to be queried for bounding box

Returns:

bounding box of the element or null is the element is unbounded

getElementBounds2D

public java.awt.geom.Rectangle2D getElementBounds2D(java.lang.Object element)

Return the high precision bounding box of the element. If the element is unbounded then this method returns null.

Parameters:

element - element to be queried for bounding box

Returns:

high precision bounding box of the element or null is the element is unbounded

elementIntersects

public boolean elementIntersects(java.lang.Object element,
                                 java.awt.geom.Rectangle2D rectangle)

Tests if the given element intersects with the given rectangle.

Parameters:

element - element to be checked for intersection

rectangle - rectangle to be checked for intersection

Returns:

true the given element intersects with the given rectangle; false otherwise

elementContains

public boolean elementContains(java.lang.Object element,
                               java.awt.geom.Point2D point)

Tests if the given element contains the given point.

Parameters:

element - element to be checked

point - point to be checked

Returns:

true the given element containes the given point; false otherwise
