             Summary: support meta annotations
                 Key: JOHNZON-87
                 URL: https://issues.apache.org/jira/browse/JOHNZON-87
             Project: Johnzon
          Issue Type: New Feature
            Reporter: Romain Manni-Bucau
            Assignee: Romain Manni-Bucau
             Fix For: 0.9.4


Idea is to allow end user to defined annotations from our annotations like in:

{code}
    public class User {
        @Id
        private long id;

        @Name
        private String name;

        @Custom
        private String custom;

        @Custom("set")
        private String custom2;

        @Ignored
        private String name2;

        public long getId() {
            return id;
        }

        public void setId(final long id) {
            this.id = id;
        }

        public String getName() {
            return name;
        }

        public void setName(final String name) {
            this.name = name;
        }

        public String getCustom() {
            return custom;
        }

        public void setCustom(final String custom) {
            this.custom = custom;
        }

        public String getName2() {
            return name2;
        }

        public void setName2(final String name2) {
            this.name2 = name2;
        }

        public String getCustom2() {
            return custom2;
        }

        public void setCustom2(final String custom2) {
            this.custom2 = custom2;
        }
    }

    @Target(FIELD)
    @Retention(RUNTIME)
    @JohnzonProperty("id")
    public @interface Id {
    }

    @Target(FIELD)
    @Retention(RUNTIME)
    @JohnzonIgnore
    public @interface Ignored {
    }

    @Target(FIELD)
    @Retention(RUNTIME)
    @JohnzonProperty("name")
    public @interface Name {
    }

    @Target(FIELD)
    @Retention(RUNTIME)
    @JohnzonProperty("ignored")
    public @interface Custom {
        String value() default "overriden";
    }
{code}
