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.

Parameters:

element - element to be queried for bounding box

Returns:

bounding box of the element

getElementBounds2D

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

Return the high precision bounding box of the element.

Parameters:

element - element to be queried for bounding box

Returns:

high precision bounding box of the element

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
