Method Detail

getProfile

protected static java.lang.String getProfile()

Get a profile String which tells the current time depending on the selected profile mode. The returned String should be formatted in a way that the user can clearly see the seconds

Returns:

A fromatted String representing the time at which this method was invoked

log

public static void log(java.lang.String s)

Log a message of unspecified type (will always be logged if logging is active). Specifying a type is always better.

Parameters:

s - The message

log

public static void log(java.lang.String message,
                       int type)

Log a message of a specific type

Parameters:

message - The message

type - Type of the message

nanoCheck

private static void nanoCheck()

Search for the method to invoke when using PROFILE_MODE_NANO

pseudoNano

private static long pseudoNano()

Pseudo method as replacement for System.nanoTime() for compatibility to 1.4

Returns:

The current nanoTime derived from System.currentTimeMillis()
