Class BoardCell
java.lang.Object
BoardCell
- All Implemented Interfaces:
- java.lang.Comparable<BoardCell>
public class BoardCell
- extends java.lang.Object
- implements java.lang.Comparable<BoardCell>
Encapsulate a (row,column) entry so that the entry
can be hashed, compared, and stored as a single
entry. This implementation provides simple methods
for determining when one BoardCell is a neighbor of
another. Here neighbor means adjacent horizontally,
vertically, or diagonally.
Method Summary |
int |
compareTo(BoardCell cell)
Returns value indicating whether cell is less
than, equal to, or greater than this cell as determined
first by row value, then by column value for
cells whose rows are equal |
boolean |
equals(java.lang.Object o)
|
int |
hashCode()

boolean |
isNeighbor(BoardCell c)
Returns true iff c is a neighbor of this board
cell; neighbor means adjacent horizontally,
vertically, or diagonally (not self). |

isNeighbor
public boolean isNeighbor(BoardCell c)
- Returns true iff c is a neighbor of this board
cell; neighbor means adjacent horizontally,
vertically, or diagonally (not self).
- Parameters:
c
- is BoardCell compared to this one
for adjacency
- Returns:
- true iff c adjacent to this BoardCell

compareTo
public int compareTo(BoardCell cell)
- Returns value indicating whether cell is less
than, equal to, or greater than this cell as determined
first by row value, then by column value for
cells whose rows are equal
- Specified by:
compareTo
in interface java.lang.Comparable<BoardCell>
- Parameters:
cell
- compared to this BoardCell
- Returns:
- row difference if rows aren't the same,
column difference if rows are the same
