org.transitime.utils.IntervalTimer

public class IntervalTimer
extends java.lang.Object

Very simple class for timing duration of events. Main use is at the beginning of the process to construct an IntervalTimer and then at the end to call elapsedMsec() to determine elapsed time.

Constructor Detail

IntervalTimer

public IntervalTimer()

Records the current time so that elapsed time can later be determined.

Method Detail

resetTimer

public void resetTimer()

Resets the timer to the current time.

elapsedMsec

public long elapsedMsec()

Time elapsed in msec since IntervalTimer created or resetTimer() called

Returns:

elapsed time in msec

elapsedNanoSec

public long elapsedNanoSec()

Time elapsed in nanoseconds since IntervalTimer created or resetTimer() called

Returns:

elapsed time in nanoseconds

elapsedMsecStr

public java.lang.String elapsedMsecStr()

For outputting elapsed time in milliseconds with 3 digits after the decimal point, as in 123.456 msec.

Returns:

String of elapsed time in milliseconds

toString

public java.lang.String toString()

toString() is defined so that it works well when debug logging. This way can pass in reference to the timer object. Only if debug logging is enabled will the toString() be called causing the string to actually be generated.

Overrides:
