Annotation Interface Option.TraverseConfig

Enclosing class:
Option
@Target(METHOD) @Retention(CLASS) public static @interface Option.TraverseConfig
Definition of how Map keys and values should be constructed.

If this annotation is not used, traversed is automatically applied on String and primitive/boxed types. In all other cases, non-traverse approach is applied.

If this annotation is used, it will use the io.helidon.config.Config#traverse method to perform a depth-first traversal of the node and its subtrees. Note: this annotation takes effect only when used in combination with Option.Configured.

For example: 

test-map:
   key: "test-value1"
   test-key:
      second-part: "test-value2"
      third-part: "test-value3"

Will be handled as: 

key: "key" value: "test-value1"
key: "test-key.second-part" value: "test-value2"
key: "test-key.third-part" value: "test-value3"
