Class TestClock

java.lang.Object

com.loomcache.server.consensus.TestClock

All Implemented Interfaces:

Clock

public class TestClock
extends Object
implements Clock

Test clock with manual time advancement for deterministic testing.

Allows tests to control the passage of time without depending on wall-clock timing. Start time is 0; advance with advance(long).

Method Details

nanoTime

public long nanoTime()

Description copied from interface: Clock

Returns the current time in nanoseconds.

The absolute value is meaningless; only differences matter. This is analogous to System.nanoTime().

Specified by:

nanoTime in interface Clock

Returns:

nanoseconds since an arbitrary reference point

advance

public void advance(long nanos)

Advance the clock by the specified amount in nanoseconds.

Parameters:

nanos - nanoseconds to advance

setTime

public void setTime(long nanos)

Set the clock to an absolute time in nanoseconds.

Parameters:

nanos - absolute time

getTime

public long getTime()

Get the current time in nanoseconds.

Returns:

current time
