Jackson 3.0.1 · tools.jackson.jr.ob.impl.EnumReader · APIdia, the JavaDoc alternative

Reader for Enum values: needed because we need a simple java.util.Map for efficient conversion from id (gotten with java.lang.Enum#toString() to value.

In future we could consider alternatively allowing use of java.lang.Enum#name() for id.
