   java.lang.SecurityManager
      edu.rice.cs.util.PreventExitSecurityManager

PreventExitSecurityManager
public class PreventExitSecurityManager extends SecurityManager (Code)
Not used anymore.

A security manager to prevent exiting the slaveVM indiscriminately. This manager disallows System.exit (unless you call PreventExitSecurityManager.exitVM ). It also disallows setting a security manager, since this would override the exit prevention! If this security manager is enabled and an exit is attempted, either via System.exit or via PreventExitSecurityManager.exitVM when exiting is blocked, a ExitingNotAllowedException will be thrown.
version:
   $Id: PreventExitSecurityManager.java 4260 2007-10-10 20:28:34Z mgricken $





Method Summary
public static  PreventExitSecurityManageractivate()
     Creates a new exit-preventing security manager, using the previous security manager to delegate to.
public  voidcheckExit(int status)
    
public  voidcheckPermission(Permission perm)
     Disallow setting security manager, but otherwise delegate to parent.
public  voiddeactivate()
     Removes this security manager.
public  booleanexitAttempted()
     Returns whether a System.exit was attempted since the last time this method was called.
public  voidexitVM(int status)
     Exits the VM unless exiting is presently blocked.
public  voidsetBlockExit(boolean b)
     Sets whether exiting the VM is unconditionally blocked or not.



Method Detail
activate
public static PreventExitSecurityManager activate()(Code)
Creates a new exit-preventing security manager, using the previous security manager to delegate to.



checkExit
public void checkExit(int status)(Code)



checkPermission
public void checkPermission(Permission perm)(Code)
Disallow setting security manager, but otherwise delegate to parent.



deactivate
public void deactivate()(Code)
Removes this security manager.



exitAttempted
public boolean exitAttempted()(Code)
Returns whether a System.exit was attempted since the last time this method was called.



exitVM
public void exitVM(int status)(Code)
Exits the VM unless exiting is presently blocked. Blocking exit is used in test cases that want to see if we try to exit.



setBlockExit
public void setBlockExit(boolean b)(Code)
Sets whether exiting the VM is unconditionally blocked or not. It's useful to block exiting to allow test cases to pretend to exit, just to make sure it would have exited under certain conditions.
Parameters:
  b - If true, exiting will never be allowed until set false.
