Method Detail

getTimeBasedSeed

public static long getTimeBasedSeed()

getTimeBasedIntSeed

public static int getTimeBasedIntSeed()

getRelativeTimeMillis

public static long getRelativeTimeMillis()

Should be used in relative constructs (for example to check how many milliseconds have passed).

Shouldn't be used in the Date creation since the value returned by this method is different in С#. For getting current time consistently use DateTimeUtil.getCurrentTimeDate().

Returns:

relative time in milliseconds.

getFreeMemory

public static long getFreeMemory()

getPropertyOrEnvironmentVariable

public static String getPropertyOrEnvironmentVariable(String name)

Gets either java property or environment variable with given name.

Parameters:

name - the name of either java property or environment variable.

Returns:

property or variable value or null if there is no such.
