Class ObjectGrid3D

java.lang.Object
sim.field.grid.AbstractGrid3D
sim.field.grid.ObjectGrid3D
All Implemented Interfaces:
Serializable, Grid3D

public class ObjectGrid3D extends AbstractGrid3D
A wrapper for 3D arrays of Objects.

This object expects that the 3D arrays are rectangular. You are encouraged to access the array directly. The object implements all of the Grid3D interface. See Grid3D for rules on how to properly implement toroidal grids.

The width and height and length (z dimension) of the object are provided to avoid having to say field[x].length, etc.

We very strongly encourage you to examine SparseGrid3D first to see if it's more appropriate to your task. If you need arbitrary numbers of Objects to be able to occupy the same location in the grid, or if you have very few Objects and a very large grid, or if your space is unbounded, you should probably use SparseGrid3D instead.

    • replaceAll

      public final void replaceAll(Object from, Object to)
      Replace instances of one value to another. Equality is measured using equals(...). null is considered equal to null. This is equivalent to calling replaceAll(from, to, false)
      Parameters:
      from - any element that matches this value will be replaced
      to - with this value
    • replaceAll

      public final void replaceAll(Object from, Object to, boolean onlyIfSameObject)
      Replace instances of one value to another. Equality is measured as follows. (1) if onlyIfSameObject is true, then objects must be "== from" to one another to be considered equal. (2) if onlyIfSameObject is false, then objects in the field must be "equals(from)". In either case, null is considered equal to null.
      Parameters:
      from - any element that matches this value will be replaced
      to - with this value
    • toArray

      public final Object[] toArray()

    • elements

      public final Bag elements()
      Returns in a Bag all stored objects (including duplicates but not null values). You are free to modify the Bag.
    • clear

      public final Bag clear()
      Sets all the locations in the grid to null, and returns in a Bag all stored objects (including duplicates but not null values). You are free to modify the Bag.
    • setTo

      public final ObjectGrid3D setTo(ObjectGrid3D values)
    • setTo

      public ObjectGrid3D setTo(Object[][][] field)

    • getNeighborsMaxDistance

      public Bag getNeighborsMaxDistance(int x, int y, int z, int dist, boolean toroidal, Bag result, IntBag xPos, IntBag yPos, IntBag zPos)
      Deprecated.
      Gets all neighbors of a location that satisfy max( abs(x-X) , abs(y-Y), abs(z-Z) ) invalid input: '<'= dist. This region forms a cube 2*dist+1 cells across, centered at (X,Y,Z). If dist==1, this is equivalent to the twenty-six neighbors surrounding (X,Y,Z), plus (X,Y) itself. Places each x, y, and z value of these locations in the provided IntBags xPos, yPos, and zPos, clearing the bags first. null may be passed in for the various bags, though it is more efficient to pass in a 'scratch bag' for each one.

      Then places into the result Bag any Objects which fall on one of these invalid input: '<'x,y,z> locations, clearning it first. Note that the order and size of the result Bag may not correspond to the X and Y and Z bags. If you want all three bags to correspond (x, y, z, object) then use getNeighborsAndCorrespondingPositionsMaxDistance(...) Returns the result Bag. null may be passed in for the various bags, though it is more efficient to pass in a 'scratch bag' for each one.

      This function may only run in two modes: toroidal or bounded. Unbounded lookup is not permitted, and so this function is deprecated: instead you should use the other version of this function which has more functionality. If "bounded", then the neighbors are restricted to be only those which lie within the box ranging from (0,0,0) to (width, height, length), that is, the width and height and length of the grid. if "toroidal", then the environment is assumed to be toroidal, that is, wrap-around, and neighbors are computed in this fashion. Toroidal locations will not appear multiple times: specifically, if the neighborhood distance is so large that it wraps completely around the width or height of the box, neighbors will not be counted multiple times. Note that to ensure this, subclasses may need to resort to expensive duplicate removal, so it's not suggested you use so unreasonably large distances.

      The origin -- that is, the (x,y,z) point at the center of the neighborhood -- is always included in the results.

      This function is equivalent to: getNeighborsMaxDistance(x,y,z,dist,toroidal ? Grid3D.TOROIDAL : Grid3D.BOUNDED, true, result, xPos, yPos,zPos);

    • getMooreNeighbors

      public Bag getMooreNeighbors(int x, int y, int z, int dist, int mode, boolean includeOrigin, Bag result, IntBag xPos, IntBag yPos, IntBag zPos)
      Gets all neighbors of a location that satisfy max( abs(x-X) , abs(y-Y), abs(z-Z) ) invalid input: '<'= dist. This region forms a cube 2*dist+1 cells across, centered at (X,Y,Z). If dist==1, this is equivalent to the twenty-six neighbors surrounding (X,Y,Z), plus (X,Y) itself. Places each x, y, and z value of these locations in the provided IntBags xPos, yPos, and zPos, clearing the bags first. null may be passed in for the various bags, though it is more efficient to pass in a 'scratch bag' for each one.

      Then places into the result Bag any Objects which fall on one of these invalid input: '<'x,y,z> locations, clearning it first. Note that the order and size of the result Bag may not correspond to the X and Y and Z bags. If you want all three bags to correspond (x, y, z, object) then use getNeighborsAndCorrespondingPositionsMaxDistance(...) Returns the result Bag. null may be passed in for the various bags, though it is more efficient to pass in a 'scratch bag' for each one.

      This function may be run in one of three modes: Grid3D.BOUNDED, Grid3D.UNBOUNDED, and Grid3D.TOROIDAL. If "bounded", then the neighbors are restricted to be only those which lie within the box ranging from (0,0,0) to (width, height), that is, the width and height of the grid. If "unbounded", then the neighbors are not so restricted. Note that unbounded neighborhood lookup only makes sense if your grid allows locations to actually be outside this box. For example, SparseGrid3D permits this but ObjectGrid3D and DoubleGrid3D and IntGrid3D and DenseGrid3D do not. Finally if "toroidal", then the environment is assumed to be toroidal, that is, wrap-around, and neighbors are computed in this fashion. Toroidal locations will not appear multiple times: specifically, if the neighborhood distance is so large that it wraps completely around the width or height of the box, neighbors will not be counted multiple times. Note that to ensure this, subclasses may need to resort to expensive duplicate removal, so it's not suggested you use so unreasonably large distances.

      You can also opt to include the origin -- that is, the (x,y,z) point at the center of the neighborhood -- in the neighborhood results.

    • getMooreNeighborsAndLocations

      public Bag getMooreNeighborsAndLocations(int x, int y, int z, int dist, int mode, boolean includeOrigin, Bag result, IntBag xPos, IntBag yPos, IntBag zPos)
      Gets all neighbors of a location that satisfy max( abs(x-X) , abs(y-Y), abs(z-Z) ) invalid input: '<'= dist. This region forms a cube 2*dist+1 cells across, centered at (X,Y,Z). If dist==1, this is equivalent to the twenty-six neighbors surrounding (X,Y,Z), plus (X,Y) itself. Places each x, y, and z value of these locations in the provided IntBags xPos, yPos, and zPos, clearing the bags first. null may be passed in for the various bags, though it is more efficient to pass in a 'scratch bag' for each one.

      For each Object which falls within this distance, adds the X position, Y position, Z position, and Object into the xPos, yPos, zPos, and result Bag, clearing them first. Some invalid input: '<'X,Y,Z> positions may not appear and that others may appear multiply if multiple objects share that positions. Compare this function with getNeighborsMaxDistance(...). Returns the result Bag. null may be passed in for the various bags, though it is more efficient to pass in a 'scratch bag' for each one.

      Deprecated.
      Gets all neighbors of a location that satisfy abs(x-X) + abs(y-Y) + abs(z-Z) invalid input: '<'= dist. This region forms an octohedron 2*dist+1 cells from point to opposite point inclusive, centered at (X,Y,Y). If dist==1 this is equivalent to the six neighbors above, below, left, and right, front, and behind (X,Y,Z)), plus (X,Y,Z) itself. Places each x, y, and z value of these locations in the provided IntBags xPos, yPos, and zPos, clearing the bags first. null may be passed in for the various bags, though it is more efficient to pass in a 'scratch bag' for each one.
