## Interface FormatFeature

-     public interface FormatFeature

  Marker interface that is to be implemented by data format - specific features. Interface used since Java Enums can not extend classes or other Enums, but they can implement interfaces; and as such we may be able to use limited amount of generic functionality.

  Note that this type is only implemented by non-JSON formats: types `JsonParser.Feature` and `JsonGenerator.Feature` do NOT implement it. This is to make it easier to avoid ambiguity with method calls.

  Since:
    2.6 (to be fully used in 2.7 and beyond)
