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:
@JsonIgnoreType class Credentials { public String password; } class Settings { public int userId; public String name; public Credentials pwd; } 
 serialization of Settings would only include properties "userId" and "name" but NOT "pwd", since it is of type annotated with @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 true meaning annotation should take effect. /**

Optional argument that defines whether this annotation is active
or not. The only use for value 'false' if for overriding purposes
(which is not needed often); most likely it is needed for use
with "mix-in annotations" ("annotation overrides").
For most cases, however, default value of "true" is just fine
and should be omitted.
