BookingSlot

public class Slot
extends TimeInterval

Class representing a (possibly infinite) slot in statistical data or schedule for some object being planned and/or simulated. Slot is a TimeInterval that can reference a Sequence of slots. Slot can either belong to some sequence, or not belong to any sequence.

Like any other TimeInterval, a slot has TimeInterval.beginTime(), TimeInterval.endTime() and TimeInterval.duration(). Both begin time and end time can be infinite. Slots of negative duration are not allowed.

Sequence, Slot and Gap classes provide basic API for scheduling.

Constructor Details

Slot

public Slot(double beginTime,
 double endTime)

Creates a new slot with the specified begin time and end time.

Parameters:

beginTime - begin time of the slot, possibly a Double.NEGATIVE_INFINITY

endTime - end time of the gap, possibly a Double.POSITIVE_INFINITY

Slot

public Slot(double beginTime,
 double endTime,
 double minDuration)

Creates a new slot with the specified begin time, end time and minimum possible duration.

Parameters:

beginTime - begin time of the slot, possibly a Double.NEGATIVE_INFINITY

endTime - end time of the gap, possibly a Double.POSITIVE_INFINITY

minDuration - minimum possible duration of this slot

Method Details

dummy

public static Slot dummy(double time)

Creates a dummy instance of Slot used primarily as a key in search and comparison methods.

Parameters:

time - time used as a search key

Returns:

dummy instance of Slot

copy

public Slot copy()

Returns a copy of this slot.

Returns:

copy of this slot

minDuration

public double minDuration()

Returns the minimum possible duration of this slot.

Returns:

minimum possible duration of this slot

sequence

public Sequence<? extends Slot> sequence()

Returns reference to Sequence to which this slot belongs, or null if this sequence does not belong to any sequence.

Returns:

reference to Sequence to which this slot belongs, or null

setMinDuration

public void setMinDuration(double minDuration)

Sets the minimum possible duration of this slot.

Note that this is mutating method; avoid using mutating methods where possible.

Parameters:

minDuration - new minimum possible duration of this slot
