public java.lang.String parseValue(java.lang.String headerValueString)

Description copied from interface: HeaderValueConverter

Parses the given string representation of a header value into an Object of type ValueType.

Specified by:

parseValue in interface HeaderValueConverter<java.lang.String>

Returns:

The header value as an object.

valueString

public java.lang.String valueString(java.lang.String headerValue)

Renders the given header value into its string reperesentation.

The given headerValue must not contain any characters that are not allowed in headers. Basically that means only characters in the ASCII range 0x20-0xff and the tab character (0x09) are allowed.

    field-value    = *( field-content / obs-fold )
    field-content  = field-vchar [ 1*( SP / HTAB ) field-vchar ]
    field-vchar    = VCHAR / obs-text
 
    obs-fold       = CRLF 1*( SP / HTAB )
                     ; obsolete line folding
                     ; see Section 3.2.4
    VCHAR          = %x21-7E
                           ; visible (printing) characters
    obs-text       = %x80-FF
