    • matchAtLeastOnce

      public static <T> boolean matchAtLeastOnce(T object, List<Filter<T>> filters)
      Algorithms for accepting the supplied object if at least one of the supplied Filters accepts 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 true from its accept method.

      Parameters:
      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.

    • noFilterMatches

      public static <T> boolean noFilterMatches(T object, 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:

    • adapt

      public static FileFilter adapt(Filter<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 List<FileFilter> adapt(List<Filter<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, List<Filter<T>> filters)
      Initializes the supplied Filters by assigning the given Log.
      Type Parameters:
      T - The Filter type.
      Parameters:
      log - The active Maven Log.
      filters - The List of Filters to initialize.

    • initialize

      public static <T> void initialize(org.apache.maven.plugin.logging.Log log, Filter<T>... filters)
      Initializes the supplied Filters by assigning the given Log.
      Type Parameters:
      T - The Filter type.
      Parameters:
      log - The active Maven Log.
      filters - The List of Filters to initialize.
