Class AsyncPageAggregatorImpl

java.lang.Object
  org.apache.jetspeed.aggregator.impl.AsyncPageAggregatorImpl

All Implemented Interfaces:

org.apache.jetspeed.aggregator.Aggregator, org.apache.jetspeed.aggregator.PageAggregator

public class AsyncPageAggregatorImpl
extends Object
implements org.apache.jetspeed.aggregator.PageAggregator

Asynchronous Page Aggregator builds the content required to render a page of portlets by rendering the portlets in parallel. Each portlet is rendered on its own thread. A work manager handles the thread pooling and synchronization of worker threads.
