READ_ENUM_KEYS_USING_INDEX
Feature that determines standard deserialization mechanism used for Enum values: if enabled, Enums are assumed to have been serialized using index ofEnum
;Note: this feature should be symmetric to as
SerializationFeature.WRITE_ENUM_KEYS_USING_INDEX
.Feature is disabled by default.
- Since:
- 2.15
-
WRITE_ENUMS_TO_LOWERCASE
Feature that determines standard serialization mechanism used for Enum values: if enabled, return value ofEnum.name().toLowerCase()
is used; if disabled, return value ofEnum.name()
is used.NOTE: this feature CAN NOT be changed on per-call basis: it will have to be set on
ObjectMapper
before useFeature is disabled by default.

name
- the name of the enum constant to be returned.- Returns:
- the enum constant with the specified name
- Throws:
IllegalArgumentException
