Examples with TaskScheduler org.apache.synapse.task.TaskScheduler used on opensource projects

Example 1 with TaskScheduler

use of org.apache.synapse.task.TaskScheduler in project wso2-synapse by wso2.

the class StartUpController method destroy.

/**
 * Remove the scheduled task completely. So only un-deployment will remove the task. Server node shutdown will keep
 * task intact in the registry.
 * <p>
 * This was introduced as a fix for product-ei#1206.
 *
 * @param removeTask whether keep the task or not.
