/**
* Marker annotation that indicates that all properties that have
* type annotated with this annotation
* are to be ignored during serialization and deserialization.
*
* Note that this does NOT mean that properties included by annotated
* type are ignored. Given hypothetical types:
*
* {@code @JsonIgnoreType}
* class Credentials {
* public String password;
* }
*
* class Settings {
* public int userId;
* public String name;
* public Credentials pwd;
* }
*
* serialization of {@code Settings} would only include properties "userId"
* and "name" but NOT "pwd", since it is of type annotated with {@code @JsonIgnoreType}.
*
* Note: annotation does have boolean 'value' property (which defaults
* to 'true'), so that it is actually possible to override value
* using mix-in annotations. Usually value is not specified as it defaults
* to {@code true} meaning annotation should take effect.
