Examples with ThreadPoolExecutor org.apache.tomcat.util.threads.ThreadPoolExecutor used on opensource projects

Example 16 with ThreadPoolExecutor

use of org.apache.tomcat.util.threads.ThreadPoolExecutor in project tomcat by apache.

the class AbstractEndpoint method setMinSpareThreads.

public void setMinSpareThreads(int minSpareThreads) {
    this.minSpareThreads = minSpareThreads;
    Executor executor = this.executor;
    if (internalExecutor && executor instanceof ThreadPoolExecutor) {
        // The internal executor should always be an instance of
        // org.apache.tomcat.util.threads.ThreadPoolExecutor but it may be
        // null if the endpoint is not running.
        // This check also avoids various threading issues.
        ((ThreadPoolExecutor) executor).setCorePoolSize(minSpareThreads);
    }
}

Example 17 with ThreadPoolExecutor

use of org.apache.tomcat.util.threads.ThreadPoolExecutor in project tomcat by apache.

the class AbstractEndpoint method shutdownExecutor.

public void shutdownExecutor() {
    Executor executor = this.executor;
    if (executor != null && internalExecutor) {
        this.executor = null;
        if (executor instanceof ThreadPoolExecutor) {
            // this is our internal one, so we need to shut it down
            ThreadPoolExecutor tpe = (ThreadPoolExecutor) executor;
            tpe.shutdownNow();
            long timeout = getExecutorTerminationTimeoutMillis();
            if (timeout > 0) {
                try {
                    tpe.awaitTermination(timeout, TimeUnit.MILLISECONDS);
                } catch (InterruptedException e) {
                // Ignore

                if (tpe.isTerminating()) {
                    getLog().warn(sm.getString("endpoint.warn.executorShutdown", getName()));
                }

            TaskQueue queue = (TaskQueue) tpe.getQueue();
            queue.setParent(null);
        }
