三维阵列上的三维洪水填充算法（Java）(3D Flood Fill Algorithm on a 3D Array (Java))

 我已经广泛搜索了论坛，并没有完全涵盖这一点。 我希望在枚举类型的数组上执行我称之为3D Flood Fill算法的操作。 我想改变它中的枚举类型，而不是改变数组元素的“颜色”。 这就是我到目前为止，如果您认为这样可行或者您有任何建议，请问我们。 
 
 /*
  * CellType is my enum type. BOUNDRY_BOX enum type is type that I line the whole 3D array with. So the
  * whole inside surface of the 3D box is filled with CellType.BOUNDRY_BOX.
  **/
 public void fillAllVoidCells(CellType[][][] grid, CellType targetType, CellType replacementType, int x, int y, int z)
 {
    if ((grid[x][y][z] != targetType) && grid[x][y][z] != CellType.BOUNDRY_BOX)
    {
        break;
    }
    else
    {
        grid[x][y][z] = replacementType;

        fillAllVoidCells(grid, targetType, replacementType, x + 1, y, z);   // right
        fillAllVoidCells(grid, targetType, replacementType, x - 1, y, z);   // left
        fillAllVoidCells(grid, targetType, replacementType, x, y + 1, z);   // in front
        fillAllVoidCells(grid, targetType, replacementType, x, y - 1, z);   // behind
        fillAllVoidCells(grid, targetType, replacementType, x, y, z + 1);   // above
        fillAllVoidCells(grid, targetType, replacementType, x, y, z - 1);   // below
    }
 }

I have searched the forums extensively and nothing quite covers this. I am looking to do what I'd call essentially a 3D Flood Fill algorithm on an array on enum types. Rather than changing the "color" of the array elements, I'd like to change the enum type in it. This is what I have so far, could you guys let me know if you think this will work or if you have any suggestions?
