Example 11 with IBlockingCondition

use of org.eclipse.scout.rt.platform.job.IBlockingCondition in project scout.rt by eclipse.

the class ExecutionSemaphoreTest method testThreePermitsAndBlocking.

/**
 * Tests execution semaphore with 3 permits and with a blocking condition involved.
 * <p>
 * In total, 7 jobs are scheduled. Thereby, job-1 and job-3 never finish, and job-2 enters a blocking condition.
 * <p>
 * This test tests, that because job-2 enters a blocking condition, job-4 starts running. Once job-4 completed, job-5
 * starts running. Then, job-5 unblocks the conditions, with lets job-2 to continue after job-5 finished. After job-2
 * finished, job-6, and then job-7 start running.
 * <p>
