Interface Clock.WarpingTimeSource

Enclosing class:

Clock

public static interface Clock.WarpingTimeSource

Facade for implementing a time source capable of being warped with respect to real time.

Method Summary

Methods

Modifier and Type	Method and Description
long	currentTimeMillis() Get the current time in milliseconds since start of epoch.
void	setCurrentTimeMillis(long ms) Set the current time in milliseconds since start of epoch.
void	setTimeOffset(long ms) Set the milliseconds of time offset relative to current time.
boolean	supportsWarping() Predicate that allows callers to determine whether the time-source supports warping operations.

Method Detail

currentTimeMillis

long currentTimeMillis()

Get the current time in milliseconds since start of epoch.

Returns:

number of milliseconds elapsed since start of epoch

See Also:

System.currentTimeMillis()

supportsWarping

boolean supportsWarping()

Predicate that allows callers to determine whether the time-source supports warping operations.

Returns:

true if time warping is supported; false otherwise

setCurrentTimeMillis

void setCurrentTimeMillis(long ms)

Set the current time in milliseconds since start of epoch. This number will be recorded as a current offset and any time elapsed from this time will be considered relative to this offset.

Parameters:

ms - number of milliseconds elapsed since start of epoch that comprises the current time

Throws:

UnsupportedOperationException - thrown if the source does not support time warping

See Also:

System.currentTimeMillis()

setTimeOffset

void setTimeOffset(long ms)

Set the milliseconds of time offset relative to current time.

Parameters:

ms - number of milliseconds of offset from the current time

Throws:

UnsupportedOperationException - thrown if the source does not support time warping
