Basic aggregation interface.
The Content Server Adapter encapsulates all aggregated related activities related to aggregation, lessening the coupling of the aggregator to the content server, which can be disabled.
Defines the interface for rendering content for a page.
Defines the interface for rendering content for a single portlet.
Portlet content is a container holding the generated content of a fragment (portlet).
The Portlet Renderer Service is the interface to processing portlet rendering requests and interfaces with the portlet container to generate the resulting markup.
The Portlet Tracking Manager will track portlets rendering statistics, taking portlets out of service when their rendering time exceeds a configurable threshold.
A rendering worker, running on its own thread if using parallel rendering.
Track rendering statistics For starter we need to have an object store its render timeout statistics
A Worker represents a single thread in the parallel aggregation engine.
The Worker Monitor is a thread manager and monitor for asynchronous (parallel) portlet aggregation and rendering.
Portlet Tracking information used in PortletTrackingManager to represent minimal data passed between the tracking manager and clients of the API
Failed to Render Fragment exceptions denote error cases where a particular fragment failed to render during content aggregation process.
Represents an exception when trying to render a portlet, but the current user did not have sufficient security access privileges to render the portlet.
