Method Detail

getObjectsAt

public java.util.List getObjectsAt(int x,
                                   int y)

Gets the List of objects at the specified coordinates. An ordered torus will return the first object inserted at the beginning of the list and the last object inserted at the end of the list. The list order is undetermined for an unordered torus.

getIteratorAt

public java.util.Iterator getIteratorAt(int x,
                                        int y)

Gets the iterator for the collection of objects at the specified coordinates. For an ordered torus the order of iteration will be first object inserted, first returned and so on. For an unordered torus, order is undefined.

getCellAt

public Cell getCellAt(int x,
                      int y)

Gets the Cell object at the specified coordinates.

getCellSizeAt

public int getCellSizeAt(int x,
                         int y)

Gets the size (number of occupants) of the cell at the specified location.

Parameters:

x - the x coordinate

y - the y coordinate

removeObjectAt

public void removeObjectAt(int x,
                           int y,
                           java.lang.Object obj)

Removes the specified object from the specified location.

Parameters:

x - the x coordinate

y - the y coordinate

obj - the object to remove
