AbstractSharedTimerSet (AppEngine :: runtime-impl 2.0.13 API)

java.lang.Object
- com.google.apphosting.runtime.timer.AbstractSharedTimerSet

All Implemented Interfaces:

TimerSet

Direct Known Subclasses:

JmxGcTimerSet, JmxHotspotTimerSet
```
public abstract class AbstractSharedTimerSet
extends Object
implements TimerSet
```
AbstractSharedTimerSet tracks a single counter that is shared by all of the Timer instances that are part of the set.
Each Timer returned by createTimer() becomes part of the set that created it, and starting or stopping that timer will increment or decrement the rate at which all other active timers are advancing.

    Description copied from interface: TimerSet
    
    Returns the number of Timer instances in this set that are currently active (i.e. Timer.start() has been called since the last Timer.stop() call.
    
    Specified by:
    
    getActiveCount in interface TimerSet
  - getCurrentShared
```
protected abstract long getCurrentShared()
```
    Returns the current value of a counter that is shared by all timers created by calling createTimer() on this instance. The rate of change of this counter will be evenly divided among started Timer instances.
  - getTitle
```
protected abstract String getTitle()
```
    Implementations should provide a short, readable string to be included in the toString() output of the timers that they create (e.g. "hotspot").
