    • parseMimeType

      public static MimeType parseMimeType(String mimeType)
      Parse the given String into a single MimeType. Recently parsed MimeType are cached for further retrieval.
      参数:
      mimeType - the string to parse
      返回:
      the mime type
      抛出:
      InvalidMimeTypeException - if the string cannot be parsed

    • parseMimeTypeInternal

      private static MimeType parseMimeTypeInternal(String mimeType)

    • parseMimeTypes

      public static List<MimeType> parseMimeTypes(String mimeTypes)
      Parse the comma-separated string into a list of MimeType objects.
      参数:
      mimeTypes - the string to parse
      返回:
      the list of mime types
      抛出:
      InvalidMimeTypeException - if the string cannot be parsed

    • tokenize

      public static List<String> tokenize(String mimeTypes)
      Tokenize the given comma-separated string of MimeType objects into a List<String>. Unlike simple tokenization by ",", this method takes into account quoted parameters.
      参数:
      mimeTypes - the string to tokenize
      返回:
      the list of tokens

    • toString

      public static String toString(Collection<? extends MimeType> mimeTypes)
      Return a string representation of the given list of MimeType objects.
      参数:
      mimeTypes - the string to parse
      返回:
      the list of mime types
      抛出:
      IllegalArgumentException - if the String cannot be parsed

    • sortBySpecificity

      public static void sortBySpecificity(List<? extends MimeType> mimeTypes)
      Sorts the given list of MimeType objects by specificity.

      Because of the computational cost, this method throws an exception when the given list contains too many elements.

      参数:
      mimeTypes - the list of mime types to be sorted
      抛出:
      IllegalArgumentException - if mimeTypes contains more than 50 elements

    • bubbleSort

      static <T> void bubbleSort(List<T> list, BiPredicate<? super T,? super T> swap)

    • initRandom

      private static Random initRandom()
      Lazily initialize the SecureRandom for generateMultipartBoundary().

    • generateMultipartBoundary

      public static byte[] generateMultipartBoundary()
      Generate a random MIME boundary as bytes, often used in multipart mime types.

    • generateMultipartBoundaryString

      public static String generateMultipartBoundaryString()
      Generate a random MIME boundary as String, often used in multipart mime types.
