      • rejectAtLeastOnce

        public static <T> boolean rejectAtLeastOnce​(T object,
                                            java.util.List<Filter<T>> filters)

        object - The object to reject (or not).
        filters - The non-null list of Filters to examine the supplied object.
        Returns:
        true if at least one of the filters returns false from its accept method.
        See Also:
        Filter.accept(Object)

      • noFilterMatches

        public static <T> boolean noFilterMatches​(T object,
                                          java.util.List<Filter<T>> filters)
        Algorithms for rejecting the supplied object if at least one of the supplied Filters rejects it.
        Type Parameters:
        T - The Filter type.
        Parameters:
        object - The object to accept (or not).
        filters - The non-null list of Filters to examine the supplied object.
        Returns:
        true if at least one of the filters return false from its accept method.

      • adapt

        public static java.io.FileFilter adapt​(Filter<java.io.File> toAdapt)
        Adapts the Filter specification to the FileFilter interface, to enable immediate use for filtering File lists.
        Parameters:
        toAdapt - The non-null Filter which should be adapted to a FileFilter interface.
        Returns:
        If the toAdapt instance already implements the FileFilter interface, simply return the toAdapt instance. Otherwise, returns a FileFilter interface which delegates its execution to the wrapped Filter.

      • adapt

        public static java.util.List<java.io.FileFilter> adapt​(java.util.List<Filter<java.io.File>> toAdapt)
        Adapts the supplied List of Filter specifications to a List of FileFilters.
        Parameters:
        toAdapt - The List of Filters to adapts.
        Returns:
        A List holding FileFilter instances. If toAdapt is null or empty, an empty list is returned from this method. Thus, this method will never return a null value.

      • initialize

        public static <T> void initialize​(org.apache.maven.plugin.logging.Log log,
                                  java.util.List<Filter<T>> filters)
