LayerLinker

This is the binding system used in JosBrowser ( JoZilla ).

Several components make up this abstract Layer class.

ApplicationLayer
PresentationLayer
SessionLayer
TransportLayer

All of these systems are used to provide a modular / layered approach to JoZilla - the mamillian munching browser.

This is the source for the abstract class LayerLinker which all layer will extend and inherit from. Checkout the Layered page on the Jozilla Spotters Guide.

<blockquote>
abstract class LayerLinker{
 Layer above;
 Layer below;
 bind (Layer above, Layer below)
 {
	this.above = above;
	this.below = below;	
 }

 sendUp (Object obj)
 {
	above.receive(obj);
 }

 sendDown (Object obj)
 {
	below.receive(obj);
 }

 receiveUp (Object obj);
 // extend this method to implement your layers
 // receive method from upper layers

 receiveDown (Object obj);
 // extend this method to implement your layers
 // receive method from lower layers}
