      • getCustomLevels

        public java.util.List<CustomLevelConfig> getCustomLevels()
        Description copied from interface: Configuration

        Returns a list of descriptors of the custom levels defined in the current configuration. The returned list does not include custom levels that are defined in code with direct calls to Level.forName(String, int).

        Note that the list does not include levels of previous configurations. For example, suppose a configuration contains custom levels A, B and C. The configuration is then modified to contain custom levels B, C and D. For the new configuration, this method will return only {B, C, D}, that is, only the custom levels defined in this configuration. The previously defined level A still exists (and can be obtained with Level.getLevel(String)), it is just not in the current configuration. Level.values() will return {A, B, C, D and the built-in levels}.

        Specified by:
        getCustomLevels in interface Configuration
        Returns:
        the custom levels defined in the current configuration
