Method Detail

assigned

public void assigned(Assignment<Request,Enrollment> assignment,
                     Enrollment value)

Called when a value is assigned to a variable. Internal number of time overlapping conflicts is updated, see TimeOverlapsCounter.getTotalNrConflicts(Assignment).

Specified by:

assigned in interface AssignmentConstraintContext<Request,Enrollment>

Parameters:

assignment - current assignment (with which this context is associated)

value - assigned value

unassigned

public void unassigned(Assignment<Request,Enrollment> assignment,
                       Enrollment value)

Called when a value is unassigned from a variable. Internal number of time overlapping conflicts is updated, see TimeOverlapsCounter.getTotalNrConflicts(Assignment).

Specified by:

unassigned in interface AssignmentConstraintContext<Request,Enrollment>

Parameters:

assignment - current assignment (with which this context is associated)

value - unassigned value

beforeAssigned

public void beforeAssigned(Assignment<Request,Enrollment> assignment,
                           long iteration,
                           Enrollment value)

Called before a value is assigned to a variable.

Parameters:

assignment - current assignment

iteration - current iteration

value - value to be assigned

afterAssigned

public void afterAssigned(Assignment<Request,Enrollment> assignment,
                          long iteration,

Called after a value is assigned to a variable.

Parameters:

assignment - current assignment

iteration - current iteration

value - value that was assigned

afterUnassigned

public void afterUnassigned(Assignment<Request,Enrollment> assignment,
                            long iteration,
