Method Detail

sleep

public static void sleep(long ms)

Sleeps for the specified number of milliseconds.

Parameters:

ms - How long to sleep

sleepAfter

public static void sleepAfter(long startTime,
                              long ms)

Sleeps for the specified number of milliseconds after the given system time in milliseconds. If that number of milliseconds has already elapsed, does nothing.

Parameters:

startTime - System time in milliseconds to sleep after

ms - How long after startTime to sleep

getComputerIdentifier

public static String getComputerIdentifier()

Generates a Computer Identifier, which may be part of a strategy to construct a licence key. (The identifier may not be unique as in one case hashcode could be same for multiple values, and the result may differ based on whether the program is running with sudo/root permission.) The identifier string is based upon the processor serial number, vendor, processor identifier, and total processor count.

Returns:

A string containing four hyphen-delimited fields representing the processor; the first 3 are 32-bit hexadecimal values and the last one is an integer value.

identifyVM

public static String identifyVM()

The function attempts to identify which Virtual Machine (VM) based on common VM signatures in MAC address and computer model.

Returns:

A string indicating the machine's virtualization info if it can be determined, or an emptry string otherwise.
