  - ### Method Detail

    - #### parseElements

          public HeaderElement[] parseElements(CharSequence buffer,
                                               ParserCursor cursor)

      Description copied from interface: `HeaderValueParser`
      Parses a header value into elements. Parse errors are indicated as `RuntimeException`.
      Specified by:
        `parseElements` in interface `HeaderValueParser`
      Parameters:
        `buffer` - buffer holding the header value to parse
        `cursor` - the parser cursor containing the current position and the bounds within the buffer for the parsing operation
      Returns:
        an array holding all elements of the header value

    - #### parseHeaderElement

          public HeaderElement parseHeaderElement(CharSequence buffer,
                                                  ParserCursor cursor)

      Description copied from interface: `HeaderValueParser`
      Parses a single header element. A header element consist of a semicolon-separate list of name=value definitions.
      Specified by:
        `parseHeaderElement` in interface `HeaderValueParser`
      Parameters:
        `buffer` - buffer holding the element to parse
        `cursor` - the parser cursor containing the current position and the bounds within the buffer for the parsing operation
      Returns:
        the parsed element

    - #### parseParameters

          public NameValuePair[] parseParameters(CharSequence buffer,
                                                 ParserCursor cursor)

      Description copied from interface: `HeaderValueParser`
      Parses a list of name-value pairs. These lists are used to specify parameters to a header element. Parse errors are indicated as `ParseException`.
      Specified by:
        `parseParameters` in interface `HeaderValueParser`
      Parameters:
        `buffer` - buffer holding the name-value list to parse
        `cursor` - the parser cursor containing the current position and the bounds within the buffer for the parsing operation
      Returns:
        an array holding all items of the name-value list

    - #### parseNameValuePair

          public NameValuePair parseNameValuePair(CharSequence buffer,
                                                  ParserCursor cursor)

      Description copied from interface: `HeaderValueParser`
      Parses a name=value specification, where the = and value are optional.
      Specified by:
        `parseNameValuePair` in interface `HeaderValueParser`
      Parameters:
        `buffer` - the buffer holding the name-value pair to parse
        `cursor` - the parser cursor containing the current position and the bounds within the buffer for the parsing operation
      Returns:
        the name-value pair, where the value is `null` if no value is specified
