Other Caché %Net Tools
Here is a brief list of some other useful classes in %Net:
Caché provides a utility class, %Net.URLParserOpens in a new tab, that you can use to parse URL strings into their component parts. This is useful, for example, when you are redirecting an HTTP request.
This class contains one class method, Parse(), that takes a string containing a URL value and returns, by reference, an array that contains the parts of the URL. For example:
Set url = "https://www.intersys.com/main.csp?QUERY=abc#anchor"
Do ##class(%Net.URLParser).Parse(url,.components)
Upon return, components will contain an array of the parts of this URL:
| Element | Value | Description |
|---|---|---|
| components(“scheme”) | http: | The transport scheme specified by this URL. |
| components(“netloc”) | www.intersys.com | The network address of the URL. |
| components(“path”) | /main.csp | The file path of the URL. |
| components(“query”) | QUERY=abc | The query string associated with the URL. |
| components(“fragment”) | anchor | The fragment (following the # character) for the URL. |
For more information, refer to the class documentation for %Net.URLParserOpens in a new tab.
You can use %Net.CharsetOpens in a new tab to represent MIME character sets within Caché and map these character sets to Caché locales. This class provides the following class methods:
-
GetDefaultCharset() returns the default character set for the current Caché locale,
-
GetTranslateTable() returns the name of the Caché translation table for a given input character set.
-
IsLocaleUnicode() indicates whether the current locale is Unicode.
-
TranslateTableExists() indicates whether the translation table for the given character set has been loaded.
For method signatures, see the class documentation for %Net.CharsetOpens in a new tab.
For more information on character sets and translation tables, see “System Classes for National Language Support” in Caché Specialized System Tools and Utilities.
You can use %Net.TelnetStreamOpens in a new tab to emulate the handshaking behavior of Windows NT Telnet.exe. For details, see the class documentation for %Net.TelnetStreamOpens in a new tab.
The %Net package provides many classes for authentication and security. For information, see the extensive class documentation.
