Constructor Detail

### Array2DMoore

    public Array2DMoore()

  Constructs a two-dimensional moore-neighborhood array of provided geometry and extent, populated with clones of provided agent.

### Array2DMoore

    public Array2DMoore(CoordinateDiscrete extent)

  Constructs a two-dimensional moore-neighborhood space array of provided geometry and extent, populated with clones of provided agent.

  Parameters:
    `extent` - a coordinate describing the size of this space

Method Detail

### calculateDistance

    public final double calculateDistance(Coordinate origin,
                                          Coordinate target)

  Returns the shortest distance between one cell and the other, assuming a walk between the two cells. In a Moore neighborhood, the distance is equal to the maximum dimension distance.

  Specified by:
    `calculateDistance` in interface `Space`
  Overrides:
    `calculateDistance` in class `Discrete`
  Parameters:
    `origin` - the starting cell
    `target` - the ending cell
  Returns:
    the double

### findWithinImpl

    public java.util.List findWithinImpl(Coordinate origin,
                                         boolean includeSelf,
                                         double distance)

  Description copied from class: `Array`
  Returns cells that are near the provided coordinate.

  Specified by:
    `findWithinImpl` in class `Array`
  Parameters:
    `origin` - the agent to find cells near
    `includeSelf` - should supplied agent be included in the return set
    `distance` - the distance to form centralCells to return cells
  Returns:
    the list
