public java.awt.Paint transform(E e)

Specified by:

transform in interface org.apache.commons.collections4.Transformer<V,E>

getColor1

protected java.awt.Color getColor1(E e)

Returns c1. Subclasses may override this method to enable more complex behavior (e.g., for picked edges).

getColor2

protected java.awt.Color getColor2(E e)

Returns c2. Subclasses may override this method to enable more complex behavior (e.g., for picked edges).
