Annotation Interface DecodeUndefinedHandlingStrategy

@Documented
@Inherited
@Retention(RUNTIME)
@Target({FIELD,TYPE})
public @interface DecodeUndefinedHandlingStrategy

This strategy can be used to influence field values while decoding if no value is found in the database. This comes in quite handy if your data model evolves and you find properties not to be encoded for old Pojos. A global default value can be set via PojoCodecProvider.Builder.decodeUndefinedHandlingStrategy(Strategy) If not set, default is DecodeUndefinedHandlingStrategy.Strategy.KEEP_POJO_DEFAULT (due to historical behaviour of PojoCodecProvider) You can use this annotation at class level or at field level. If you use it at class level, you can override each field with a field level annotation.

• DecodeUndefinedHandlingStrategy.Strategy.SET_TO_NULL sets the value of the field to null, even if the pojo provides a default value
• DecodeUndefinedHandlingStrategy.Strategy.CODEC TypeCodec.defaultInstance() is being used to initialize the field, even if the pojo provides a default value
• DecodeUndefinedHandlingStrategy.Strategy.KEEP_POJO_DEFAULT keeps the pojo default, could be null or anything set during creation (constructor or default initialization of the field)
