Value of URI as a String.

Declaration :

• Uml : + value : String, multiplicity : 1
• C++ : public: string value
• Java : public String value

A distributed information "space" in which information objects exist.
The scheme simultaneously specifies an information space and a mechanism for
accessing objects in that space. For example if scheme = "ftp", it identifies
the information space in which all ftpable objects exist, and also the
application - ftp - which can be used to access them.
Values may include: "ftp", "telnet", "mailto", "gopher" and many others.
Refer to WWW URI RFC for a full list.
New information spaces can be accommodated within the URI specification.

Declaration :

• Uml : + scheme() : String
• C++ : public: string scheme()
• Java : public String scheme()

A string whose format is a function of the scheme. Identifies the location in <scheme>-space of an information entity.
Typical values include hierarchical directory paths for any machine. For example, with scheme = "ftp", path might be
/pub/images/image_01. The strings "." and ".." are reserved for use in the path. Paths may include internet/intranet location identifiers of the form:
sub_domain...domain, e.g. "info.cern.ch"

Declaration :

• Uml : + path() : String
• C++ : public: string path()
• Java : public String path()

A part of, a fragment or a sub-function within an object.
Allows references to sub-parts of objects, such as a certain line and
character position in a text object. The syntax and semantics are
defined by the application responsible for the object.

Declaration :

• Uml : + fragment_id() : String
• C++ : public: string fragment_id()
• Java : public String fragment_id()

Query string to send to application implied by scheme and path.
Enables queries to applications, including databases to be included
in the URI. Supports any query meaningful to the server, including SQL.

Declaration :

• Uml : + query() : String
• C++ : public: string query()
• Java : public String query()
