```
public void check(java.lang.String name)
```
    Check status of a specific web application and reload, redeploy or deploy it as necessary. This method is for use with functionality such as management web applications that upload new/updated web applications and need to trigger the appropriate action to deploy them. This method assumes that the web application is currently marked as serviced and that any uploading/updating has been completed before this method is called. Any action taken as a result of the checks will complete before this method returns.
    
    Parameters:
    name - The name of the web application to check
  - checkUndeploy
```
public void checkUndeploy()
```
    Check for old versions of applications using parallel deployment that are now unused (have no active sessions) and undeploy any that are found.
