Class SimulationGrid

public class SimulationGrid

Class to represent a grid in a biological simulation, the "model" in terms of M/C/V. This object wears two hats in the sense that is exposes a different interface to different objects in the system. The viewer/controller sees this as a Simulator, and the agents (grid inhabitants) and related classes see it as an AgentGrid.

Method Detail

width

public int width()

Find the width of this grid. Getter method for width.

Returns:

the width of this grid.

height

public int height()

Find the height of this grid. Getter method for height.

Returns:

the height of this grid.

isOccupied

public boolean isOccupied(int xPos,
                 int yPos)

Determine if a position is occupied by an agent. Just check the position in the array.

Parameters:

xPos - The x-position in which we're looking

yPos - The y-position in which we're looking

Returns:

Whether or not there is an agent at the specified position.

isOpen

public boolean isOpen(int xPos,
             int yPos)

Determine if a position is open to be occupied by an agent.

Parameters:

xPos - The x-position in which we're looking

yPos - The y-position in which we're looking

Returns:

Whether or not an agent can be placed at the specified position.

getAgentAt

public Agent getAgentAt(int xPos,
               int yPos)

Find the agent, if any, at a position. Return whatever is in the position in the array.

Parameters:

xPos - The x-position in which we're looking

yPos - The y-position in which we're looking

Returns:

The agent at the position, if any (null otherwise)

setAgentAt

public void setAgentAt(int xPos,
              int yPos,
              Agent agent)

Set the agent at a given position.

Parameters:

xPos - The x-position in which we're looking

yPos - The y-position in which we're looking

agent - The agent to place there

Precondition:

xPos and yPos must be within the grid
