@Target(value={ANNOTATION_TYPE,METHOD})
@Retention(value=RUNTIME)
public @interface JsonSetter

Marker annotation that can be used to define a non-static, single-argument method to be used as a "setter" for a logical property as an alternative to recommended JsonProperty annotation (which was introduced in version 1.1).

Setter means that when a property with matching name is encountered in JSON content, this method will be used to set value of the property.

NOTE: this annotation was briefly deprecated for version 1.5; but has since been un-deprecated to both allow for asymmetric naming (possibly different name when reading and writing JSON), and more importantly to allow multi-argument setter method in future.
