Marker annotation that can be used to define a non-static, no-argument value-returning (non-void) method to be used as a "getter" for a logical property. It can be used as an alternative to more general JsonProperty annotation (which is the recommended choice in general case). 

Getter means that when serializing Object instance of class that has
this method (possibly inherited from a super class), a call is made
through the method, and return value will be serialized as value of
the property.
