Class ThreadPools


  • public class ThreadPools
    extends Object
    A factory for thread pools. Each pool has a name and the details are taken from the configuration in the following as follows:
    • threadpool.pool_name.core: the number of threads to keep in the pool, even if they are idle (defalut value: 5)
    • threadpool.pool_name.max: the maximum number of threads to allow in the pool (defalut value: 10)
    • threadpool.pool_name.keepalive: this is the maximum time(in seconds) that excess idle threads will wait for new tasks before terminating (defalut value: 5)
