GradientEdgePaintTransformer (JUNG (parent metadata project) 2.1.1 API)

java.lang.Object
- edu.uci.ics.jung.visualization.decorators.GradientEdgePaintTransformer<V,E>

All Implemented Interfaces:

com.google.common.base.Function<E,java.awt.Paint>, java.util.function.Function<E,java.awt.Paint>

Direct Known Subclasses:

PluggableRendererDemo.GradientPickedEdgePaintFunction
```
public class GradientEdgePaintTransformer<V,E>
extends java.lang.Object
implements com.google.common.base.Function<E,java.awt.Paint>
```
Creates GradientPaint instances which can be used to paint an Edge. For DirectedEdges, the color will blend from c1 (source) to c2 (destination); for UndirectedEdges, the color will be c1 at each end and c2 in the middle.

protected java.awt.Color getColor1(E e)
```
    Returns c1. Subclasses may override this method to enable more complex behavior (e.g., for picked edges).
    
    Parameters:
    
    e - the edge for which a color is to be retrieved
    
    Returns:
    
    the constructor-supplied color c1
  - 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).
    
    Parameters:
    
    e - the edge for which a color is to be retrieved
    
    Returns:
    
    the constructor-supplied color c2
