com.j_spaces.kernel.time
Class SystemTime

java.lang.Object
  com.j_spaces.kernel.time.SystemTime

public final class SystemTime
extends Object

A static system time wrapper, which will call the underlying ITimeProvider implementation.

usage:

long time = SystemTime.timeMillis();

AbsoluteTime is the default implementation of ITimeProvider. Custom time implementations can be provided by use of a system property. The value of the property should name a class implementing ITimeProvider interface.

 e.g. for applying a "relative time" provider, you can either:
 
 1. Set via System property: (recommended option)
 
        -Dcom.gs.time-provider=com.j_spaces.kernel.time.RelativeTime
 
 2. Set via container xml-tag value:
 
        <time-provider>com.j_spaces.kernel.time.RelativeTime</time-provider>
 
 

All known implementations, can be queried as follows:

SystemTime.isAbsoluteTime();

SystemTime.isRelativeTime();

Method Detail

timeMillis

public static long timeMillis()

Returns the time in milliseconds specified by the underlying ITimerProvider implementation. Note that while the unit of time of the return value is a millisecond, the granularity of the value depends on the time-provider implementation and may be larger.

Returns:

the difference, measured in milliseconds, between the system time and lifetime of the JVM.

getTimeProviderName

public static String getTimeProviderName()

Returns:

TimeProvider class name of object representing this provider

isRelativeTime

public static boolean isRelativeTime()

Returns:

true if time-provider is of RelativeTime

isAbsoluteTime

public static boolean isAbsoluteTime()

Returns:

true if time-provider is of AbsoluteTime
