Detailed Description

The url class provides read access to urls.

Its parent class: file provides provides open(), read(), and close() methods.

http urls, with Basic Authentication, are supported on all platforms.

urls for other protocols, including ftp, https, scp, sftp, and others, are supported if rudiments was compiled with support for libcurl.

Examples of supported urls include:

The url class supports storing the user:password portion of a url in a user-password file. These files may be referenced in the url by enclosing the full pathname of the file in square brackets. The file should consist of a single line containing the user and password, separated by a colon.

For example:

myusername:mypassword

Constructor & Destructor Documentation

◆ url()

url::url ( )

Creates an instance of the url class.

◆ ~url()

virtual url::~url ( )
virtual

Deletes this instance of the url class.
