Clouway User Flagged Attendance Reviewer
Seen/unseen flags with many users.
Usage
Here is an example of how the library is used.
Suppose we have a task that is scheduled for completion and we are making changes to its schedule. A general workflow will look like:
/*
...
FlagService flagService = <new FlagService instance>
Task task = <new Task instance>
...
*/
// Create a flag instance
ChangeFlag taskScheduleFlag = new TaskScheduleFlag();
// Making changes to the schedule
flagService.addFlagChange(taskScheduleFlag, dateOfUpdate, task.getId());
// An attender(user or someone else) looks at the schedule
flagService.seeFlag(taskScheduleFlag, taskList, attender, dateBeforeUpdate);
// Apply the flag values to one or more tasks
flagService.applyFlags(attender, taskList, new TaskScheduleFlagApplier());
Configuration
Your change flags should implement the ChangeFlag interface and be annotated with the @FlagFor annotation, like so:
@FlagFor(target = "Task", flagName = "TaskSchedule")
class TaskScheduleFlag implements ChangeFlag<Task, Long> {
@Override
public Long getReferenceId(Task task) {
return task.getId();
}
}
Also you need a FlagApplier for each of your flags:
@ApplierForFlag(TaskScheduleFlag.class)
class TaskScheduleFlagApplier implements FlagApplier<Task, Long> {
@Override
public void apply(Task task, boolean flagSeen) {
/* implementation for applying the flagSeen value to the task instance */
}
@Override
public Long getReferenceId(Task task) {
return task.getId();
}
}
