EnumCollections

Port of Java's EnumSet collection to C#

EnumSet

Overview

• Performance characteristics are similar to the Java's EnumSet.
• More efficient with Enum types that have less than or equal to 64 values.
• Static factory methods similar to the Java version are provided: EnumSet.Of(Bird.Stork, ...)

Notes

1. Enum constants defined with the same value are treated as aliases:

   public enum Bird { 
       BlueJay,        // 0
       Stork,          // 1
       Puffin,         // 2
       SeaParrot = 2,  // 2
       Chicken         // 3
   }
   
   var a = EnumSet.Of(Bird.SeaParrot);
   var b = EnumSet.Of(Bird.Puffin)
   Assert.That(a, Is.EqualTo(b)));

2. When creating an empty EnumSet, you must specify the type:

   var a = EnumSet.Of<Bird>()
