Constructor Detail

ManualClock

public ManualClock()

Create a new instance.

ManualClock

public ManualClock(long wallInit,
                   long monotonicInit)

Create a new instance.

Parameters:

wallInit - Initial value for the wall time.

monotonicInit - Initial value for the monotonic time.

Method Detail

wallTime

public long wallTime()

Description copied from interface: Clock

Current wall time in milliseconds since the epoch. Typically equivalent to System.currentTimeMillis.

Specified by:

wallTime in interface Clock

monotonicTime

public long monotonicTime()

Description copied from interface: Clock

Current time from a monotonic clock source. The value is only meaningful when compared with another snapshot to determine the elapsed time for an operation. The difference between two samples will have a unit of nanoseconds. The returned value is typically equivalent to System.nanoTime.

Specified by:

monotonicTime in interface Clock

setWallTime

public void setWallTime(long t)

Set the wall time to the value t.

setMonotonicTime

public void setMonotonicTime(long t)

Set the monotonic time to the value t.
