Examples with StaticService org.apache.camel.StaticService used on opensource projects

Example 1 with StaticService

use of org.apache.camel.StaticService in project camel by apache.

the class DefaultExecutorServiceManager method onThreadPoolCreated.

/**
     * Invoked when a new thread pool is created.
     * This implementation will invoke the {@link LifecycleStrategy#onThreadPoolAdd(org.apache.camel.CamelContext,
     * java.util.concurrent.ThreadPoolExecutor, String, String, String, String) LifecycleStrategy.onThreadPoolAdd} method,
     * which for example will enlist the thread pool in JMX management.
     *
     * @param executorService the thread pool
     * @param source          the source to use the thread pool
     * @param threadPoolProfileId profile id, if the thread pool was created from a thread pool profile
