printCoordinate
public static java.lang.String printCoordinate(int xy)
getIntStack
public static IntStack getIntStack()
- Allocate an IntStack of default size. Instead of allocating
new objects each time, the objects created through this method
can be 'recycled' and then reused. This is much more efficient
than relying on the VM to allocate an object and then later
garbage-collect it again.

getNlib
public static final int getNlib(int startXY,
int max,
byte color,
byte[] board)
- Same as the other getNlib method except it doesn't store the liberties.

getNlib
public static final int getNlib(int startXY,
int max,
byte color,
byte[] board,
IntStack libertyStack)
- Get the number of liberties of a chain. The stones are in the 'board'
array that is passed in. The liberties are put on the stack parameter.
Only a maximum number of liberties are retrieved, depending on the 'max'
parameter. If the starting point is empty, then the liberties
are counted as if a stone of 'color' was played there.

getPoint

- Allocate an UniqueList. Instead of allocating

can be 'recycled' and then reused. This is much more efficient
than relying on the VM to allocate an object and then later
