org.apache.cocoon.profiling.statistics
Class CollectorImpl

java.lang.Object
  org.apache.avalon.framework.logger.AbstractLogEnabled
      org.apache.cocoon.profiling.statistics.CollectorImpl

All Implemented Interfaces:

Disposable, Component, Contextualizable, LogEnabled, Serviceable, ThreadSafe, Collector, Store

public class CollectorImpl
extends AbstractLogEnabled
implements Collector, Store, ThreadSafe, Serviceable, Disposable, Contextualizable

Implementation for the statistics component. In order to prevent an out of memory exception we implement the Store interface (dummy implementation) so we can register this component with the StoreJanitor component which will invoke this component to free memory in case of low memory.

Since:

2.1.10
