A two-dimensional space providing effecient implementations for von Neumann
neighbors. In a von Neumann neighborhood, cells are considered neighbors if
they share an edge with the target:

Array2DEuclidian
public Array2DEuclidian()
- Constructs a two-dimensional Euclidian array.
Array2DEuclidian
public Array2DEuclidian(CoordinateDiscrete extent)
- Constructs a two-dimensional space array of provided geometry and extent,
populated with clones of provided agent.
- Parameters:
extent
- a coordinate describing the size of this space
calculateNeighbors
public java.util.List calculateNeighbors(Node cell)
- Description copied from class:
Discrete
- Calculate neighbors.
- Overrides:
calculateNeighbors
in class Discrete
- Parameters:
cell
- the cell
- Returns:
- the list
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 nearincludeSelf
- should supplied agent be included in the return setdistance
- the distance to form centralCells to return cells
- Returns:
- the list
calculateDistance
public 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 Euclidian space, this distance is equal
to the dimension root of the sum of each dimension distance squared.

calculateDistance
in interface Space
- Overrides:
calculateDistance
in class Discrete
- Parameters:
origin
- the starting celltarget
