Package org.apache.logging.log4j.status

Class StatusLogger.PropertiesUtilsDouble

  • Enclosing class:
    StatusLogger
    static final class StatusLogger.PropertiesUtilsDouble
extends java.lang.Object
    This is a thin double of PropertiesUtil.

    We could have used PropertiesUtil, PropertyFilePropertySource, etc. Consequently, they would delegate to LoaderUtil, etc. All these mechanisms expect a working StatusLogger. In order to be self-sufficient, we cannot rely on them, hence this double.

      • isRelevantPropertyName

        private static boolean isRelevantPropertyName​(@Nullable java.lang.Object propertyName)
        Filter to exclude irrelevant property names (i.e., non-string and not log4j-prefixed) to speed up matching.
        Parameters:
        propertyName - a property name
        Returns:
        true, if the property name is relevant; false, otherwise

      • normalizePropertyName

        private static java.lang.String normalizePropertyName​(java.lang.String propertyName)
        An imperfect property name normalization routine.

        It is imperfect, because foo.bar would match with fo.obar. But it is good enough for the StatusLogger needs.

        Parameters:
        propertyName - the input property name
        Returns:
        the normalized property name
