Constructor Detail

ReservationGrid

public ReservationGrid(int xNum,
                       int yNum,
                       double gridTimeStep)

Create a reservation grid.

Parameters:

xNum - the number of time tiles in the x direction

yNum - the number of time tiles in the y direction

gridTimeStep - the time step.

Method Detail

cleanUp

public void cleanUp(double currentTime)

Clean up the reservation grid.

Parameters:

currentTime - the current time

getXnum

public int getXnum()

Get the number of time tiles in the x direction.

Returns:

the number of time tiles in the x direction

getYnum

public int getYnum()

Get the number of time tiles in the y direction.

Returns:

the number of time tiles in the y direction

calcX

public int calcX(int tid)

The x coordinate of the time tile.

Parameters:

tid - the ID of the time tile

Returns:

the x coordinate of the time tile.

calcY

public int calcY(int tid)

The y coordinate of the time tile.

Parameters:

tid - the ID of the time tile

Returns:

the y coordinate of the time tile.

calcTileId

public int calcTileId(int x,
                      int y)

Get the ID of the time tile at a given coordinate.

Parameters:

x - the x-coordinate

y - the y-coordinate

Returns:

the ID of the time tile at a given coordinate

getxNum

public int getxNum()

Get the number of time tiles in the x direction.

Returns:

the number of time tiles in the x direction.

getyNum

public int getyNum()

Get the number of time tiles in the y direction.

Returns:

getGridTimeStep

public double getGridTimeStep()

Get the time step.

Returns:

the time step

calcDiscreteTime

public int calcDiscreteTime(double time)

Get the time of a given discrete time.

Parameters:

discreteTime - the time

Returns:

the time

getLastReservedTime

public double getLastReservedTime()

Get the last time at which any time-tile has been reserved.

Returns:

the last time at which any time-tile has been reserved; -1 if there is currently no reservation.

getReservedTilesAtTime

public List<Integer> getReservedTilesAtTime(double time)

Get the set of all reserved tiles at a given discrete time.

Parameters:

time - the time
