Example 6 with Constraint

use of co.cask.cdap.internal.schedule.constraint.Constraint in project cdap by caskdata.

the class Schedulers method toProgramSchedule.

public static ProgramSchedule toProgramSchedule(ApplicationId appId, ScheduleSpecification spec) {
    Schedule schedule = spec.getSchedule();
    ProgramType programType = ProgramType.valueOfSchedulableType(spec.getProgram().getProgramType());
    ProgramId programId = appId.program(programType, spec.getProgram().getProgramName());
