edu.internet2.middleware.grouperClientExt.org.apache.commons.httpclient.util.ParameterFormatter
public class ParameterFormatter extends Object

This formatter produces a textual representation of attribute/value pairs. It comforms to the generic grammar and formatting rules outlined in the Section 2.1 and Section 3.6 of RFC 2616

2.1 Augmented BNF

Many HTTP/1.1 header field values consist of words separated by LWS or special characters. These special characters MUST be in a quoted string to be used within a parameter value (as defined in section 3.6). 

 token          = 1*
 separators     = "(" | ")" | "<" | ">" | "@"
                | "," | ";" | ":" | "\" | <">
                | "/" | "[" | "]" | "?" | "="
                | "{" | "}" | SP | HT

A string of text is parsed as a single word if it is quoted using double-quote marks. 

 quoted-string  = ( <"> *(qdtext | quoted-pair ) <"> )
 qdtext         = <any TEXT except <">>

The backslash character ("\") MAY be used as a single-character quoting mechanism only within quoted-string and comment constructs. 

 quoted-pair    = "\" CHAR
3.6 Transfer Codings

Parameters are in the form of attribute/value pairs. 

 parameter               = attribute "=" value
 attribute               = token
 value                   = token | quoted-string
