      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

      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:
