Constructor Detail

ThreadStatistics

public ThreadStatistics(@Nullable
                        java.lang.Thread thread)

Creates a tracker to monitor the specified thread (or null to indicate each call is to refer to whatever the calling thread is)

Parameters:

thread - The thread to track, or null to indicate calls reflect the calling thread

ThreadStatistics

public ThreadStatistics(long idToTrack)

Creates a tracker to monitor the specified thread (or a negative number to indicate each call is to refer to whatever the calling thread is)

Parameters:

idToTrack - The thread id to track, or a negative number to indicate calls reflect the calling thread

Method Detail

getThreadTime

public long getThreadTime()

Returns the amount of time the thread has been active, in nanoseconds, or -1 if the JVM doesn't support thread time operations. This excludes time spent blocked or waiting on other operations or threads. Once the tracked thread is no longer active, this will consistently return the same value, which is the last measured value for how long the thread was active

Returns:

The amount of time the thread has been active, in nanoseconds, or -1 if the JVM doesn't support thread time operations

getThreadId

public long getThreadId()

Returns the id of the thread being tracked (or a negative or 0 value if the calls to this statistics object simply return data about the current thread)

Returns:

The id of the thread being tracked (or a negative or 0 value if the calls to this statistics object simply return data about the current thread)

isThreadEnded

public boolean isThreadEnded()

Returns whether or not the tracked thread is still running (or blocked, etc... --- just not dead). If no thread is tracked, this will always return true

Returns:

True if the tracked thread is still alive

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
