      • getGroupedName

        public static java.lang.String getGroupedName​(java.lang.String serviceName,
                                              java.lang.String groupName)
        Returns a combined string with serviceName and groupName. serviceName can not be nil.

        In most cases, serviceName can not be nil. In other cases, for search or anything, See getGroupedNameOptional(String, String)

        etc:

        serviceName | groupName | result

        serviceA | groupA | groupA@@serviceA

        nil | groupA | threw IllegalArgumentException

        返回:
        'groupName@@serviceName'

      • getServiceName

        public static java.lang.String getServiceName​(java.lang.String serviceNameWithGroup)

      • getGroupName

        public static java.lang.String getGroupName​(java.lang.String serviceNameWithGroup)

      • checkServiceNameFormat

        public static void checkServiceNameFormat​(java.lang.String combineServiceName)
        check combineServiceName format. the serviceName can't be blank. 
         serviceName = "@@";                 the length = 0; illegal
 serviceName = "group@@";            the length = 1; illegal
 serviceName = "@@serviceName";      the length = 2; illegal
 serviceName = "group@@serviceName"; the length = 2; legal
        参数:
        combineServiceName - such as: groupName@@serviceName

      • getGroupedNameOptional

        Returns a combined string with serviceName and groupName. Such as 'groupName@@serviceName'

        This method works similar with getGroupedName(java.lang.String, java.lang.String) But not verify any parameters.

        etc:

        serviceName | groupName | result

        serviceA | groupA | groupA@@serviceA

        nil | groupA | groupA@@

        nil | nil | @@
