public class BitGroup extends java.lang.Object
Class used to organize long values into sets of values with overlapping bits. For example, if you had values 1,2,3, 8, 12, you could partition them into two bit groups. The values 1,2,3, would be in one bit group because they all either use the "1" or "2" bit (If there was on "3", then 1 and 2 could be in separate groups). Also the values "8" and "12" are in the same group since they share the "8" bit.

Method Detail

intersects
public boolean intersects(BitGroup bitGroup)
Tests if this bit group has any overlapping bits with the given bit group.- Parameters:
bitGroup
- the BitGroup to test for overlap.- Returns:
- true if the groups have any bits in common.
-
merge
public void merge(BitGroup bitGroup)
Merges the given BitGroup into the group. All of its values will be added to this group's values and the masks will be or'ed together.- Parameters:
bitGroup
- the BitGroup to merge into this one.
