Class TPCThreadManager
java.lang.Object
org.apache.avalon.framework.logger.AbstractLogEnabled
org.apache.excalibur.event.command.AbstractThreadManager
org.apache.excalibur.event.command.TPCThreadManager
- All Implemented Interfaces:
- Disposable, Initializable, LogEnabled, Parameterizable, java.lang.Runnable, ThreadManager
- public final class TPCThreadManager
- extends AbstractThreadManager
- implements Parameterizable
This is a ThreadManager that uses a certain number of threads per
processor. The number of threads in the pool is a direct proportion to
the number of processors. The size of the thread pool is (processors
threads-per-processor) + 1
