/**
 * Decorator 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 {@link JsonProperty} decorator.
 *
 * Setter means that when deserializing Object instance of class that has this method
 * (possibly inherited from a super class), a call is made through the method.
 *
 * @example
 * ```typescript
 * class User {
 *   @JsonProperty() @JsonClassType({type: () => [Number]})
 *   id: number;
 *   @JsonProperty() @JsonClassType({type: () => [String]})
 *   firstname: string;
 *   @JsonProperty() @JsonClassType({type: () => [String]})
 *   lastname: string;
 *   @JsonProperty() @JsonClassType({type: () => [Array, [String]]})
 *   fullname: string[];
 *
 *   @JsonGetter() @JsonClassType({type: () => [String]})
 *   getFullname(): string {
 *     return this.firstname + ' ' + this.lastname;
 *   }
 *
 *   @JsonSetter()
 *   setFullname(fullname: string) {
 *     this.fullname = fullname.split(' ');
 *   }
 * }
