Method Detail

values

public static Jvm[] 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 (Jvm c : Jvm.values())
    System.out.println(c);

Returns:

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

valueOf

public static Jvm 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

is64Bit

public static boolean is64Bit()

getProcessId

public static int getProcessId()

vmSupportsCS8

public static boolean vmSupportsCS8()

getUniqueTid

public static long getUniqueTid()

This may or may not be the OS thread id, but should be unique across processes

Returns:

a unique tid of up to 48 bits.

getUniqueTid

public static long getUniqueTid(Thread thread)

isWindows

                                               throws IOException

Throws:

IOException

checkInterrupted

Utility method to support throwing checked exceptions out of the streams API

Parameters:

t - the exception to rethrow

Returns:

the exception

trimStackTrace
