Constructor Detail

DaemonThreadPool

public DaemonThreadPool(int coreSize,
                long keepAliveSecs,
                int shutdownWaitSeconds,
                String namePrefix)

Construct the DaemonThreadPool.

Parameters:

coreSize - the core size of the thread pool.

keepAliveSecs - the time in seconds idle threads are keep alive

shutdownWaitSeconds - the time in seconds allowed for the pool to shutdown nicely. After this the pool is forced to shutdown.

Method Detail

registerShutdownHook

public void registerShutdownHook()

Register a shutdown hook with the JVM Runtime.

shutdown

public void shutdown()

Shutdown this thread pool nicely if possible.

This will wait a maximum of 20 seconds before terminating any threads still working.
