Class Platform

  +--lava.Platform

public class Platform

extends java.lang.Object

Characterizes the host platform.

Details: Platform provides information about the current platform on which the JVM is running. This class does not provide any additional information beyond that which is already available through System.getProperty calls, but hopefully it does make access to -- and interpretation of -- that information a bit easier.

This class is always under development as new Java platforms are being introduced. If you wish to encourage the development of this class, please return the output of the following code:

import java.util.Enumeration; import java.util.Properties; class DumpProperties { public static void main (String[] args) { Properties p = System.getProperties (); Enumeration keys = p . keys (); while (keys . hasMoreElements ()) { String key = (String) keys . nextElement (); String value = (String) p . get (key); System.out . println (key + "=" + value); } } }

Currently available dumps are available here.

Field Detail

UNKNOWN

public static final int UNKNOWN

Indicates unknown information.

Details: UNKNOWN indicates that some item of information could not be determined. For example, if you are caching the return value of get_os_genre, you can cache this value to avoid clashes with the other constants defined in this class.

UNIX

public static final int UNIX

Unix-style operating system.

Details: UNIX indicates any of the Unix-style operating systems.

MS_DOS

public static final int MS_DOS

Microsoft MS-DOS operating system.

Details: MS_DOS indicates the Microsoft MS-DOS operating system family.

MACINTOSH

public static final int MACINTOSH

Apple Macintosh operating system.

Details: MACINTOSH indicates the Apple Macintosh operating system family.

WINDOWS

public static final int WINDOWS

Microsoft Windows.

Details: WINDOWS indicates the Microsoft Windows operating system family.

public Platform()

Method Detail

getOsGenre

public static final int getOsGenre()

Determines host operating system family.

Details: get_os_genre identifies the operating system genre hosting the currently running JVM.

This implementation recognizes only Linux (UNIX), Windows (WINDOWS), Macintosh (MACINTOSH), and HP-UX (UNIX). If the initialization procedure detects any other platform, it will assume UNIX.

The author is currently in the process of collecting System.getProperty("os.name") values for as many platforms as possible, so that the initialization procedure can be expanded. Submissions are welcome.

getLineSeparator

public static final java.lang.String getLineSeparator()

Returns platform's line separator.

Details: getLineSeparator returns the default line separator for the host platform.

Returns:

the line separator
