The component request life cycle is an interface that defines a contract for a component for being involved into a request:

public interface ComponentRequestLifecycle

{

   /**

    * Start a request.

    * @param container the related container

    */

   void startRequest(ExoContainer container);

 

   /**

    * Ends a request.

    * @param container the related container

    */

   void endRequest(ExoContainer container);

}

The container passed is the container to which the component is related. This contract is often used to setup a thread local based context that will be demarcated by a request.

For instance in the GateIn portal context, a component request life cycle is triggered for user requests. Another example is the initial data import in GateIn that demarcates using callbacks made to that interface.
