Class RenderingBean

java.lang.Object

ome.services.RenderingBean

All Implemented Interfaces:

java.io.Serializable, ServiceInterface, StatefulServiceInterface, RenderingEngine

@Transactional(readOnly=true)
public class RenderingBean
extends java.lang.Object
implements RenderingEngine, java.io.Serializable

Provides the RenderingEngine service. This class is an Adapter to wrap the Renderer so to make it thread-safe.

The multi-threaded design of this component is based on dynamic locking and confinement techniques. All access to the component's internal parts happens through a RenderingEngineImpl object, which is fully synchronized. Internal parts are either never leaked out or given away only if read-only objects. (The only exception are the CodomainMapContext objects which are not read-only but are copied upon every method invocation so to maintain safety.)

Finally the RenderingEngine component doesn't make use of constructs that could compromise liveness.

Since:

3.0-M3
