java.lang.Object
   nextapp.echo2.app.AwtImageReference

AwtImageReference
public class AwtImageReference implements ImageReference(Code)
An ImageReference describing an image which may be rendered from a java.awt.Image. Note that the JVM running the Echo Application Container will require access to a graphics context for the Java AWT to function.



Constructor Summary
public  AwtImageReference()
     Default constructor for use only when a class is derived from AwtImageReference and the getImage() method is overridden.
public  AwtImageReference(Image image)
     Creates an AwtImageReference to the specified java.awt.Image.

Method Summary
public  booleanequals(Object o)
    
public  ExtentgetHeight()
    
public  ImagegetImage()
     Retrieves the image.
public  StringgetRenderId()
    
public  ExtentgetWidth()
    


Constructor Detail
AwtImageReference
public AwtImageReference()(Code)
Default constructor for use only when a class is derived from AwtImageReference and the getImage() method is overridden.



AwtImageReference
public AwtImageReference(Image image)(Code)
Creates an AwtImageReference to the specified java.awt.Image. Note that changes to the underlying image will not necessarily be reflected on the client unless the image-containing property of the target component is update.
Parameters:
  image - the java.awt.Image to be displayed.




Method Detail
equals
public boolean equals(Object o)(Code)

See Also:   java.lang.Object.equals(java.lang.Object)



getHeight
public Extent getHeight()(Code)

See Also:   nextapp.echo2.app.ImageReference.getHeight



getImage
public Image getImage()(Code)
Retrieves the image. Calls to this method will be minimized such that applications may extend this class and override this method such that images are created only when they are needed, thereby reducing memory usage at the cost of increased processor workload. You should also override the getWidth() and getHeight() methods.



getRenderId
public String getRenderId()(Code)

See Also:   nextapp.echo2.app.RenderIdSupport.getRenderId



getWidth
public Extent getWidth()(Code)

See Also:   nextapp.echo2.app.ImageReference.getWidth
