示例1: midpoint
import org.apache.cassandra.utils.FBUtilities; //导入方法依赖的package包/类
public Token midpoint(Token ltoken, Token rtoken)
{
// the symbolic MINIMUM token should act as ZERO: the empty bit array
BigInteger left = ltoken.equals(MINIMUM) ? ZERO : ((BigIntegerToken)ltoken).token;
BigInteger right = rtoken.equals(MINIMUM) ? ZERO : ((BigIntegerToken)rtoken).token;
Pair<BigInteger,Boolean> midpair = FBUtilities.midpoint(left, right, 127);
// discard the remainder
return new BigIntegerToken(midpair.left);
}
