      • getPriority

        int getPriority()

        int

      • licenseIsValid

        boolean licenseIsValid​(String subject)
        Check if an installed license with the given subject is valid or not. The set of subjects that are valid is defined by the implementation.

        LicenseInstallResult installLicense​(Location... locations)

After calling this method, clients still need to check licenseIsValid().
