                Resource[] resources)

Constructor.

Parameters:

activity - parent activity

slot - starting time

resources - selection of resources

Location

public Location(Activity activity,
                int day,
                int hour,
                Resource[] resources)

Constructor. slot = nrHours * day + hour

Parameters:

Method Detail

getSlot

public int getSlot()

Gets slot

getResources

getNrOfDiscouragedSlots

public int getNrOfDiscouragedSlots()

Number of slots (over all resources) which are discouraged

toDouble

public double toDouble()

Int value (for optimization) -- getNrOfDiscouragedSlots() is returned

Overrides:

toDouble in class Value

computeNrOfDiscouragedSlots

public int computeNrOfDiscouragedSlots()

Computes number of discouraged slots (over all resources and the activity)

hasIntersection

public boolean hasIntersection(Location location)
