SimpleTimer2 (Javadocs [I2P+ 2.13.0+]

java.lang.Object
- net.i2p.util.SimpleTimer2

```
public class SimpleTimer2
extends Object
```
Scheduled event executor backed by ScheduledThreadPoolExecutor. Replaces the legacy SimpleTimer (deleted; had lock contention issues). Supports cancel and reschedule. Events must NOT block. All timer events should extend TimedEvent and use schedule()/cancel() directly.

- Constructor Detail
  - SimpleTimer2
```
public SimpleTimer2(I2PAppContext context)
```
    To be instantiated by the context. Others should use context.simpleTimer2() instead
    Parameters:
    context - the I2P application context
  - SimpleTimer2
```
public SimpleTimer2(I2PAppContext context,
                    String name)
```
    To be instantiated by the context. Others should use context.simpleTimer2() instead, except for dedicated timers that need a distinct thread name.
    Parameters:
    context - the I2P application context
    name - the timer name, used for the timer thread name
  - SimpleTimer2
```
protected SimpleTimer2(I2PAppContext context,
                       String name,
                       boolean prestartAllThreads)
```
    To be instantiated by the context. Others should use context.simpleTimer2() instead
    Parameters:
    context - the I2P application context
    name - the timer name
    prestartAllThreads - whether to prestart all threads
- Method Detail
  - addEvent
```
public void addEvent(SimpleTimer2.TimedEvent event,
                     long timeoutMs)
```
    Queue up the given event to be fired no sooner than timeoutMs from now. Pool is set automatically from this timer.
    Parameters:
    event - to be run once
    timeoutMs - run after this delay
  - addPeriodicEvent
```
public void addPeriodicEvent(SimpleTimer2.TimedEvent event,
                             long timeoutMs)
```
    Schedule a periodic event backed by SimpleTimer2.TimedEvent. The event self-reschedules via schedule() in timeReached().
    Parameters:
    event - the event
    timeoutMs - period in ms between executions
    Throws:
    IllegalArgumentException - if timeoutMs less than 5000
  - addPeriodicEvent
```
public void addPeriodicEvent(SimpleTimer2.TimedEvent event,
                             long delay,
                             long timeoutMs)
```
    Schedule a periodic event backed by SimpleTimer2.TimedEvent.
    Parameters:
    event - the event
    delay - run the first iteration after delay ms
    timeoutMs - period in ms between executions
    Throws:
    IllegalArgumentException - if timeoutMs less than 5000
  - getInstance
```
public static SimpleTimer2 getInstance()
```
    If you have a context, use context.simpleTimer2() instead
    Returns:
    the global SimpleTimer2 instance
  - stop
```
public void stop()
```
    Stops the timer. Subsequent executions will not throw RejectedExecutionException. Cannot be restarted.
  - toString
```
public String toString()
```
    Overrides:
    toString in class Object
    Returns:
    the timer name
