Grails checks if a class has a static variable with a specific value

Question

I have a class in grails like:

class Autoresponder {
    static String TYPE_NONE = "none"
    static String TYPE_GETRESPONSE = "GetResponse"
    static String TYPE_MAILCHIMP = "MailChimp"
    static String TYPE_AWEBER = "AWeber"
    static String TYPE_INFUSIONSOFT = "InfusionSoft"
    static String TYPE_ICONTACT = "iContact"
    static String TYPE_SENDY = "Sendy"
    static String TYPE_ACTIVECAMPAIGN = "ActiveCampaign"
    static String TYPE_API_ACTIVATE = "activate"
    static String TYPE_ONTRAPORT = "ontraport"

    //rest of code
}

I want to just find that the above class has a static variable with a value AWeber. How can I do it? Is there a way to get all the static user variables in the class (and thereby compare each variable value with what I want)?

EDIT: For some technical reasons, I cannot change the class definition.

Answer 1

Just iterate over all the static fields that are looking for the one that has the desired value. As in the following groovy script example

import static java.lang.reflect.Modifier.isStatic

class Autoresponder {
    static String TYPE_NONE = "none"
    static String TYPE_GETRESPONSE = "GetResponse"
    static String TYPE_MAILCHIMP = "MailChimp"
    static String TYPE_AWEBER = "AWeber"
    static String TYPE_INFUSIONSOFT = "InfusionSoft"
    static String TYPE_ICONTACT = "iContact"
    static String TYPE_SENDY = "Sendy"
    static String TYPE_ACTIVECAMPAIGN = "ActiveCampaign"
    static String TYPE_API_ACTIVATE = "activate"
    static String TYPE_ONTRAPORT = "ontraport"
}    

def getStaticAttributeWithValue(Class clazz, Object searchedValue) {
    clazz.declaredFields
        .findAll{ isStatic(it.modifiers) }
        .find { clazz[it.name] == searchedValue }
}

assert getStaticAttributeWithValue(Autoresponder, "AWeber") != null
assert getStaticAttributeWithValue(Autoresponder, "NonExist") == null

null, , . ( java.lang.reflect.Field)

, groovy MetaClass,

def getStaticAttributeWithValue(Class clazz, Object searchedValue) {
    clazz.metaClass.properties
        .findAll{ it.getter.static }
        .find { clazz[it.name] == searchedValue }
}

groovy.lang.MetaBeanProperty

Answer 3

MetaClass. - ( ... ):

String val
if(Autoresponder.metaClass.static.AWeber){
    val = Autoresponder.AWeber
}

MetaClass .
