Method Detail

atStage

public static void atStage(String desc)

Deprecated.

Marks the current stage of the thread for profiling.

Parameters:

desc - a description of the current stage

Takes a snapshot of the current thread state if the thread has been blocked longer than the specified threshold.

Returns:

a String representation of the thread's stack trace and the time blocked, or null if the thread has been blocked less than the threshold.

takeSnapshot

public static String takeSnapshot(long threshold)

Deprecated.

Takes a snapshot of the current thread state if the thread has been blocked longer than the specified threshold.

Parameters:

threshold - the time threshold in nanoseconds

Returns:

a String representation of the thread's stack trace and the time blocked, or null if the thread has been blocked less than the threshold.

finished

public static void finished()

Deprecated.

Marks the current thread as finished for profiling.

sleepSilently

@Deprecated
public static void sleepSilently(int millis)

Deprecated. Use Jvm.pause(long) instead
