Example 2 with ExternalTaskQueryBuilder

the class FetchAndLockHandlerImpl method executeFetchAndLock.

protected List<LockedExternalTaskDto> executeFetchAndLock(FetchExternalTasksExtendedDto fetchingDto, ProcessEngine processEngine) {
    ExternalTaskQueryBuilder fetchBuilder = fetchingDto.buildQuery(processEngine);

Example 3 with ExternalTaskQueryBuilder

use of org.camunda.bpm.engine.externaltask.ExternalTaskQueryBuilder in project camunda-bpm-platform by camunda.

the class ExternalTaskRestServiceImpl method fetchAndLock.

}

Example 4 with ExternalTaskQueryBuilder

use of org.camunda.bpm.engine.externaltask.ExternalTaskQueryBuilder in project camunda-bpm-platform by camunda.

the class ExternalTaskServiceTest method testFetchAndLockWithInitialBuilder.

/**
 * Note: this does not test a hard API guarantee, i.e. the test is stricter than the API (Javadoc).
 * Its purpose is to ensure that the API implementation is less error-prone to use.
 *
 * Bottom line: if there is good reason to change behavior such that this test breaks, it may
 * be ok to change the test.
