[infinispan-issues] [JBoss JIRA] (ISPN-3069) TimeService implementation

[Pedro Ruivo (JIRA)]

     [ https://issues.jboss.org/browse/ISPN-3069?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Pedro Ruivo updated ISPN-3069:
------------------------------

    Description: 
Implementation of the TimeService as described in the mailling list http://lists.jboss.org/pipermail/infinispan-dev/2013-April/012667.html

Interface can be found here: https://github.com/pruivo/infinispan/blob/ISPN-3069/core/src/main/java/org/infinispan/util/TimeService.java

Default implementation will wrap System.nanoTime() and System.currentTimeMillis().

Provide also a no-op implementation?

other suggestions are welcome.

Implementation of the TimeService as described in the mailling list http://lists.jboss.org/pipermail/infinispan-dev/2013-April/012667.html

Interface
{code}
long time() //return the current time in nanoseconds
long wallClockTime() //return the current clock time in milliseconds

long timeDuration(long startTime) //duration between current time and startTime. return value >=0 
long wallClockDuration(long startClockTime) //duration between current clock time and startClockTime. it can be negative

long timeDuration(long startTime, long endTime) //duration between endTime and startTime. return value >= 0 
long wallClockDuration(long startClockTime, long endClockTime) //duration between startClockTime and endClockTime. it can be negative

//other possible methods
double convertNanosecondsToMicroseconds(long nanos) //convert from nanos to micros without losing precision
double convertNanosecondsToSeconds(long nanos) //convert from nanos to seconds without losing precision

boolean isExpired(long currentWallClock, long endWallClock) //returns true if the endWallClock has expired
{code}

Default implementation will wrap System.nanoTime() and System.currentTimeMillis().

Provide also a no-op implementation?

other suggestions are welcome.
