Examples with CamelThreadFactory org.apache.camel.util.concurrent.CamelThreadFactory used on opensource projects

Example 1 with CamelThreadFactory

use of org.apache.camel.util.concurrent.CamelThreadFactory in project camel by apache.

the class DefaultJmsMessageListenerContainer method createDefaultTaskExecutor.

/**
     * Create a default TaskExecutor. Called if no explicit TaskExecutor has been specified.
     * <p />
     * The type of {@link TaskExecutor} will depend on the value of
     * {@link JmsConfiguration#getDefaultTaskExecutorType()}. For more details, refer to the Javadoc of
     * {@link DefaultTaskExecutorType}.
     * <p />
     * In all cases, it uses the specified bean name and Camel's {@link org.apache.camel.spi.ExecutorServiceManager}
     * to resolve the thread name.
     * @see JmsConfiguration#setDefaultTaskExecutorType(DefaultTaskExecutorType)
     * @see ThreadPoolTaskExecutor#setBeanName(String)
