Jackson 2.18.2 · com.fasterxml.jackson.jr.ob.impl.EnumReader

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.

Doc from com.fasterxml.jackson.jr.ob.api.ValueReader.readNext. Method called to deserialize value of type supported by this reader, using given parser. Parser is not yet positioned to the (first) token of the value to read and needs to be advanced. Default implementation simply calls `p.nextToken()` first, then calls {#link `read(JSONReader, JsonParser)`, but some implementations may decide to implement this differently to use (slightly) more efficient accessor in `JsonParser`, like `JsonParser#nextIntValue(int)`.
