At the moment, constraint streams require us to duplicate constraints in some cases:
constraint.filter(task -> task.getPriority() == Priority.MAJOR)
.penalize("Major priority task end time",
BendableScore.ofSoft(0, 2, 0, 1),
Task::getEndTime);
}
constraint.filter(task -> task.getPriority() == Priority.MINOR)
.penalize("Minor priority task end time",
BendableScore.ofSoft(0, 2, 1, 1),
Task::getEndTime);
}
Notice that the constraints are identical, except for the constraint weight (BendableScore), which depends on a property of the entity. This could be simplified and also made more performant, if we indeed replaced this by one constraint like this:
constraint.penalize("Task end time", task -> { if (task.getPriority() == Priority.MAJOR) { return BendableScore.ofSoft(0, 2, 0, 1); } else { return BendableScore.ofSoft(0, 2, 1, 1); } }, Task::getEndTime); }
This example is adapted from OptaPlanner's TaskAssigning example, which would need updating when this feature is implemented.
