Check Enum Availability

MY ENUM CHECK

Enum Example

Enum with EnumSet

enum UserGroupType {
    MYSAVEDGROUP('My Saved Group', 50, 1),
    RESULTGROUP('Result Group', 50, Double.POSITIVE_INFINITY),
    RESULT_COMPARE("Comparing Individual with Group", 50, Double.POSITIVE_INFINITY),
    GROUP_COMPARE("Comparing Two or more Groups", 50, Double.POSITIVE_INFINITY),
    GROUPDEFAULT("default", 50, Double.POSITIVE_INFINITY)

    final String value
    final int limit
    final int max

    UserGroupType(String value) {
        this.value = value
        this.limit = 0
        this.max = 0
    }

    UserGroupType(String value, limit, max) {
        this.value = value
        this.limit = limit
        this.max = max
    }

    static def canDelete = EnumSet.of(RESULTGROUP, RESULT_COMPARE, GROUP_COMPARE, GROUPDEFAULT)

    boolean isDeletableType() {
        return canDelete.contains(this)
    }


    String toString() {
        value
    }

    String getKey() {
        name()
    }

}    

Enum with static method

    final String id
    final String desc

            println "id: " + color.id + ", desc:" + color.desc
            map.put(color.id, color)
        }

    }

    }
}
