    • canContain

      default boolean canContain(Class<?> type)
      Checks if this handler can contain the given type of element. The default implementation checks if the given type is assignable to any of the types returned by elementTypes().

      type - The type to check.
      Returns:
      true if this handler can contain the given type, false otherwise.
