Method Detail

values

public static OperatingSystem[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (OperatingSystem c : OperatingSystem.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static OperatingSystem valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getCurrentOperatingSystem

public static OperatingSystem getCurrentOperatingSystem()

Gets the operating system that the JVM runs on from the java system properties. this method returns UNKNOWN, if the operating system was not successfully determined.

Returns:

The enum constant for the operating system, or UNKNOWN, if it was not possible to determine.

isWindows

public static boolean isWindows()

Checks whether the operating system this JVM runs on is Windows.

Returns:

true if the operating system this JVM runs on is Windows, false otherwise

isLinux

public static boolean isLinux()

Checks whether the operating system this JVM runs on is Linux.

Returns:

true if the operating system this JVM runs on is Linux, false otherwise

isMac

public static boolean isMac()

Checks whether the operating system this JVM runs on is Windows.

Returns:

true if the operating system this JVM runs on is Windows, false otherwise

isFreeBSD

public static boolean isFreeBSD()

Checks whether the operating system this JVM runs on is FreeBSD.

Returns:

true if the operating system this JVM runs on is FreeBSD, false otherwise
