SynapseThreadPool

public SynapseThreadPool(int corePoolSize,
                         int maximumPoolSize,
                         long keepAliveTime,
                         TimeUnit unit,
                         BlockingQueue<Runnable> workQueue)

Constructor for the Synapse thread poll

Parameters:

corePoolSize - - number of threads to keep in the pool, even if they are idle

maximumPoolSize - - the maximum number of threads to allow in the pool

keepAliveTime - - this is the maximum time that excess idle threads will wait for new tasks before terminating.

unit - - the time unit for the keepAliveTime argument.

workQueue - - the queue to use for holding tasks before they are executed.

SynapseThreadPool

public SynapseThreadPool()
