Method Details

clearFlags

public AppointmentValidationBuilder<Context> clearFlags()

Clears all flags that are used for validation. Must be called before validateAppointment(Object, Appointment, EAppointmentActionType, Range).

Returns:

This for chaining.

flags

public AppointmentValidationBuilder<Context> flags(EAppointmentBookingFlag... flags)

Uses the given flags for validation. Must be called before validateAppointment(Object, Appointment, EAppointmentActionType, Range).

Parameters:

flags - Flags to use for validation. They are added to the existing flags.

Returns:

This for chaining.

flags

public AppointmentValidationBuilder<Context> flags(Set<EAppointmentBookingFlag> flags)

Uses the given flags for validation. Must be called before validateAppointment(Object, Appointment, EAppointmentActionType, Range).

Parameters:

flags - Flags to use for validation. They are added to the existing flags.

Returns:

This for chaining.

getAllErrors

public com.google.common.collect.ImmutableList<EAppointmentBookingError> getAllErrors()

Returns:

All errors that have occurred so far by calls to validateAppointment(Object, Appointment, EAppointmentActionType, Range).

getSuccessfullyModified

public com.google.common.collect.ImmutableSet<UUID> getSuccessfullyModified()

Returns:

The appointments that required validation because of a change and that were validated successfully.

getSuccessfullyModifiedCount

public int getSuccessfullyModifiedCount()

Returns:

The number of appointments that required validation because of a change and that were validated successfully.

now

public AppointmentValidationBuilder<Context> now(Instant now)

Parameters:

now - An instant to use as the current server time.

Returns:

This for chaining.

registerAppointment

public void registerAppointment(Appointment appointment,
 EAppointmentActionType actionType)

Registers an appointment to be validated. This is called automatically by validateAppointment(Object, Appointment, EAppointmentActionType, Range). However, when you wish to validate multiple appointments, you should call this method on all appointments first. This ensures an optimal order of validation, e.g. booking an appointment at 12:00 o'clock and then cancelling an existing appointment at 12:00 o'clock does not work, but canceling the existing one first and then booking the other appointment works.

If you call this method on an appointment, you must also later call validateAppointment(Object, Appointment, EAppointmentActionType, Range), or the total validation result getAllErrors() may be wrong.

Parameters:

appointment - Appointment that will be validated later.

actionType - Action that would be applied to the appointment.

validateAppointment

public Set<EAppointmentBookingError> validateAppointment(Context ctx,
 Appointment appointment,
 EAppointmentActionType actionType,
 com.google.common.collect.Range<Instant> newTime)

Validates the given appointment and returns all validation errors. Appointments that previously validated successfully can block slots.

Parameters:

ctx - Context for the data access object.

appointment - Appointment to validate.

actionType - Action that would be performed with the appointment.

newTime - New time of a moved appointment. Should be null otherwise.

Returns:

All validation errors of the given appointment.

validateAppointment

public Set<EAppointmentBookingError> validateAppointment(Context ctx,
 Appointment appointment,
 SubmittedAppointment action)

Validates the given appointment and returns all validation errors. Appointments that previously validated successfully can block slots.

Parameters:
