Hi All:
IMHO, EnumSet provides a set view of enum types. According to its spec,
"Enum sets are represented internally as bit vectors".
To avoid to re-invent the wheel, it could be more reasonable to utilize
java.util.BitSet class to support the implementation of EnumSet.
While current API methods provided by BitSet is not enough, I need to
extend the function provided by BitSet. There are 2 options:
1. Implement these extension methods in BitSet directly as package
private methods
2. Construct a package private utility class in
org.apache.harmony.luni.util package, and implement extensions in this
implementation class.
I prefer the first option, since there is not many classes need these
extension. If no objections, I will adopt the first schema.
Best regards.
