class TUri: public TObject


TUri

This class represents a RFC 3986 compatible URI.
See http://rfc.net/rfc3986.html.
It provides member functions to set and return the different
the different parts of an URI. The functionality is that of
a validating parser.

const TString GetUri()
 Returns the whole URI -
 an implementation of chapter 5.3 component recomposition.
 The result URI is composed out of the five basic parts.

 URI         = scheme ":" hier-part [ "?" query ] [ "#" fragment ]
 hier-part   = "//" authority path-abempty
             / path-absolute
             / path-rootless
             / path-empty
const TString RemoveDotSegments(const TString& )

 This is an implementation of the pseudocode in chapter 5.2.2.
const TString MergePaths(const TUri& reference, const TUri& base)
 RFC 3986, 5.3.2.
 If the base URI has a defined authority component and an empty
 path, then return a string consisting of "/" concatenated with the
 reference's path; otherwise,
 return a string consisting of the reference's path component
 appended to all but the last segment of the base URI's path (i.e.,
 excluding any characters after the right-most "/" in the base URI
 path, or excluding the entire base URI path if it does not contain
 any "/" characters).
