- - ### Constructor Detail

    - #### BufferedHeader

          public BufferedHeader(CharArrayBuffer buffer)
                         throws ParseException

      Creates a new header from a buffer. The name of the header will be parsed immediately, the value only if it is accessed.
      Parameters:
        `buffer` - the buffer containing the header to represent
      Throws:
        `ParseException` - in case of a parse error

  - ### Method Detail

    - #### create

          public static BufferedHeader create(CharArrayBuffer buffer)

      Since:
        5.0

    - #### getName

          public String getName()

      Description copied from interface: `NameValuePair`
      Gets the name of this pair.
      Specified by:
        `getName` in interface `NameValuePair`
      Returns:
        the name of this pair, never `null`.

    - #### getValue

          public String getValue()

      Description copied from interface: `NameValuePair`
      Gets the value of this pair.
      Specified by:
        `getValue` in interface `NameValuePair`
      Returns:
        the value of this pair, may be `null`.

    - #### isSensitive

          public boolean isSensitive()

      Description copied from interface: `Header`
      Returns `true` if the header should be considered sensitive.

      Some encoding schemes such as HPACK impose restrictions on encoded representation of sensitive headers.

      Specified by:
        `isSensitive` in interface `Header`
      Returns:
        `true` if the header should be considered sensitive.

    - #### getValuePos

          public int getValuePos()

      Description copied from interface: `FormattedHeader`
      Obtains the start of the header value in the `buffer`. By accessing the value in the buffer, creation of a temporary string can be avoided.
      Specified by:
        `getValuePos` in interface `FormattedHeader`
      Returns:
        index of the first character of the header value in the buffer returned by `getBuffer`.

    - #### getBuffer

          public CharArrayBuffer getBuffer()

      Description copied from interface: `FormattedHeader`
      Obtains the buffer with the formatted header. The returned buffer MUST NOT be modified.
      Specified by:
        `getBuffer` in interface `FormattedHeader`
