    • Method Detail

      • terminated

        protected void terminated()
        Overrides:
        terminated in class java.util.concurrent.ThreadPoolExecutor

      • execute

        public void execute​(java.lang.Runnable command)
        Specified by:
        execute in interface java.util.concurrent.Executor
        Overrides:
        execute in class java.util.concurrent.ThreadPoolExecutor

      • afterExecute

        protected void afterExecute​(java.lang.Runnable r,
                            java.lang.Throwable t)
        Overrides:
        afterExecute in class java.util.concurrent.ThreadPoolExecutor

      • getTasks

        public java.util.stream.Stream<java.lang.Runnable> getTasks()
        Returns a stream of all pending tasks. This is similar to ThreadPoolExecutor.getQueue() but will expose the originally submitted Runnable instances rather than potentially wrapped ones.

      • toString

        public final java.lang.String toString()
        Overrides:
        toString in class java.util.concurrent.ThreadPoolExecutor

      • appendThreadPoolExecutorDetails

        protected void appendThreadPoolExecutorDetails​(java.lang.StringBuilder sb)
        Append details about this thread pool to the specified StringBuilder. All details should be appended as key/value pairs in the form "%s = %s, "
        Parameters:
        sb - the StringBuilder to append to

      • wrapRunnable

        protected java.lang.Runnable wrapRunnable​(java.lang.Runnable command)

      • unwrap

        protected java.lang.Runnable unwrap​(java.lang.Runnable runnable)
