TimeUnit
abstract class TimeUnit implements java.io.Serializable(Code)
A TimeUnit represents time durations at a given unit of granularity and provides utility methods to convert across units, and to perform timing and delay operations in these units. A TimeUnit does not maintain time information, but only helps organize and use time representations that may be maintained separately across various contexts. A nanosecond is defined as one thousandth of a microsecond, a microsecond as one thousandth of a millisecond, a millisecond as one thousandth of a second, a minute as sixty seconds, an hour as sixty minutes, and a day as twenty four hours.

A TimeUnit is mainly used to inform time-based methods how a given timing parameter should be interpreted. For example, the following code will timeout in 50 milliseconds if the org.apache.beehive.netui.util.concurrent.locks.Lock lock is not available:

  Lock lock = ...;
 if ( lock.tryLock(50L, TimeUnit.MILLISECONDS) ) ...
 
while this code will timeout in 50 seconds:
 Lock lock = ...;
 if ( lock.tryLock(50L, TimeUnit.SECONDS) ) ...
 
Note however, that there is no guarantee that a particular timeout implementation will be able to notice the passage of time at the same granularity as the given TimeUnit.

Internal constructor




Method Detail
convert
abstract public long convert(long duration, TimeUnit unit)(Code)
Convert the given time duration in the given unit to this unit. Conversions from finer to coarser granularities truncate, so lose precision. For example converting 999 milliseconds to seconds results in 0. Conversions from coarser to finer granularities with arguments that would numerically overflow saturate to Long.MIN_VALUE if negative or Long.MAX_VALUE if positive.
Parameters:
  duration - the time duration in the given unit
Parameters:
  unit - the unit of the duration argument the converted duration in this unit,or Long.MIN_VALUE if conversion would negativelyoverflow, or Long.MAX_VALUE if it would positively overflow.



excessNanos
abstract int excessNanos(long d, long m)(Code)
Utility to compute the excess-nanosecond argument to wait, sleep, join.
Parameters:
  d - the duration
Parameters:
  m - the number of millisecondss the number of nanoseconds



sleep
public void sleep(long timeout) throws InterruptedException(Code)
Perform a Thread.sleep using this unit. This is a convenience method that converts time arguments into the form required by the Thread.sleep method.
Parameters:
  timeout - the minimum time to sleep
throws:
  InterruptedException - if interrupted while sleeping.
See Also:   java.lang.Thread.sleep



timedJoin
public void timedJoin(Thread thread, long timeout) throws InterruptedException(Code)
Perform a timed Thread.join using this time unit. This is a convenience method that converts time arguments into the form required by the Thread.join method.
Parameters:
  thread - the thread to wait for
Parameters:
  timeout - the maximum time to wait
throws:
  InterruptedException - if interrupted while waiting.
See Also:   java.lang.Thread.join(longint)



timedWait
public void timedWait(Object obj, long timeout) throws InterruptedException(Code)
Perform a timed Object.wait using this time unit. This is a convenience method that converts timeout arguments into the form required by the Object.wait method.

For example, you could implement a blocking poll method (see BlockingQueue.poll BlockingQueue.poll ) using:

  public synchronized  Object poll(long timeout, TimeUnit unit) throws InterruptedException {
 while (empty) {
 unit.timedWait(this, timeout);
 ...
 }
 }

Parameters:
  obj - the object to wait on
Parameters:
  timeout - the maximum time to wait.
throws:
  InterruptedException - if interrupted while waiting.
See Also:   java.lang.Object.wait(longint)



toDays
abstract public long toDays(long duration)(Code)
Equivalent to DAYS.convert(duration, this).
Parameters:
  duration - the duration the converted duration
See Also:   TimeUnit.convert



toHours
abstract public long toHours(long duration)(Code)
Equivalent to HOURS.convert(duration, this).
Parameters:
  duration - the duration the converted duration,or Long.MIN_VALUE if conversion would negativelyoverflow, or Long.MAX_VALUE if it would positively overflow.
See Also:   TimeUnit.convert



toMicros
abstract public long toMicros(long duration)(Code)
Equivalent to MICROSECONDS.convert(duration, this).
Parameters:
  duration - the duration the converted duration,or Long.MIN_VALUE if conversion would negativelyoverflow, or Long.MAX_VALUE if it would positively overflow.
See Also:   TimeUnit.convert



toMillis
abstract public long toMillis(long duration)(Code)
Equivalent to MILLISECONDS.convert(duration, this).
Parameters:
  duration - the duration the converted duration,or Long.MIN_VALUE if conversion would negativelyoverflow, or Long.MAX_VALUE if it would positively overflow.
See Also:   TimeUnit.convert



toMinutes
abstract public long toMinutes(long duration)(Code)
Equivalent to MINUTES.convert(duration, this).
Parameters:
  duration - the duration the converted duration,or Long.MIN_VALUE if conversion would negativelyoverflow, or Long.MAX_VALUE if it would positively overflow.
See Also:   TimeUnit.convert



toNanos
abstract public long toNanos(long duration)(Code)
Equivalent to NANOSECONDS.convert(duration, this).
Parameters:
  duration - the duration the converted duration,or Long.MIN_VALUE if conversion would negativelyoverflow, or Long.MAX_VALUE if it would positively overflow.
See Also:   TimeUnit.convert



toSeconds
abstract public long toSeconds(long duration)(Code)
Equivalent to SECONDS.convert(duration, this).
Parameters:
  duration - the duration the converted duration,or Long.MIN_VALUE if conversion would negativelyoverflow, or Long.MAX_VALUE if it would positively overflow.

toString
public String toString()(Code)



values
public static TimeUnit[] values()(Code)



x
static long x(long d, long m, long over)(Code)
