WatchDogTimer

java.lang.Object
- soot.Transformer
- - soot.SceneTransformer
  - - ptolemy.copernicus.kernel.WatchDogTimer

All Implemented Interfaces:

soot.HasPhaseOptions
```
public class WatchDogTimer
extends soot.SceneTransformer
implements soot.HasPhaseOptions
```
A transformer that calls System.exit() after a certain amount of time. This transformer is useful for killing tests that are in tight loops. We use a transformer instead of building this directly into the KernelMain class to get parameter handling for free.

  - internalTransform
```
protected void internalTransform(java.lang.String phaseName,
                                 java.util.Map options)
```
    Start up a watch dog timer that will call System.exit(). Sample option arguments:
    -p wjtp.watchDogTimer time:10000
    means that exit will be called in 10,000 ms, or 10 seconds
    Specified by:
    
    internalTransform in class soot.SceneTransformer
    
    Parameters:
    
    phaseName - The name of the phase, for example wjtp.watchDogTimer.
    
    options - The options Map. This method uses the time option to specify the number of milliseconds until System.exit() should be called.
