Class java.util.concurrent.ThreadPoolExecutor

Examples of java.util.concurrent.ThreadPoolExecutor.allowCoreThreadTimeOut()

java.util.concurrent.ThreadPoolExecutor.allowCoreThreadTimeOut()
Sets the policy governing whether core threads may time out and terminate if no tasks arrive within the keep-alive time, being replaced if needed when new tasks arrive. When false, core threads are never terminated due to lack of incoming tasks. When true, the same keep-alive policy applying to non-core threads applies also to core threads. To avoid continual thread replacement, the keep-alive time must be greater than zero when setting {@code true}. This method should in general be called before the pool is actively used. @param value {@code true} if should time out, else {@code false} @throws IllegalArgumentException if value is {@code true}and the current keep-alive time is not greater than zero @since 1.6
