-------------------------------
Summary: MathUtils.isPowerOf2 does not cover the case of value=0
Key: FLINK-33725
URL: https://issues.apache.org/jira/browse/FLINK-33725
Project: Flink
Issue Type: Improvement
Components: API / Core
Reporter: Jes Cok
org.apache.flink.util.MathUtils.isPowerOf2,
This static method does not cover the case of value=0.
Should the document explain that value cannot be =0?
Or could it be re implemented as the following code?
public static boolean isPowerOf2(long value) {
return value > 0 && (value & (value - 1)) == 0;
}
