Class 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.

cancel

public void cancel()

getPhaseName

public java.lang.String getPhaseName()

Specified by:

getPhaseName in interface soot.HasPhaseOptions

getDefaultOptions

public java.lang.String getDefaultOptions()

Specified by:

getDefaultOptions in interface soot.HasPhaseOptions

getDeclaredOptions

public java.lang.String getDeclaredOptions()

Specified by:

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.
