doldol

doldol packs multiple flaggable data in a Flag value, and checks its flags by cheap operators.

In the current version, doldol will handle Enum e in a list only.

The name

doldol comes from Korean word 돌돌 which is a mimetic presenting roll up fabrics or something like flags.

Gap analysis

EnumSet

EnumSet is good library, but only works with List (ex. toEnum). I also need List interface only. However, next version of my simulation project needs to support Traversal class. Therefore, I keep to develop this. Of course, you can use EnumSet with fromList or etc., but when you consider performance seriously, let think one more time.
