- Method Detail
  - getConstraint
```
AuthorizationConstraint getConstraint(javax.servlet.http.HttpServletRequest request)
                               throws javax.servlet.ServletException,
                                      java.io.IOException
```
    Determine the AuthorizationConstraint that applies to a resource.
    
    Parameters:
    
    request - an HttpServletRequest object that contains the request the client has made of the servlet
    
    Returns:
    
    AuthorizationConstraint instance if a constraint applies to the request. null if no constraint applies to the request. USE_DEFAULT_CONSTRAINTS if this method cannot determine what constraint applies to the request, and therefore the runtime's default AuthorizationConstraint discovery logic will be applied to the request.
    
    Throws:
    
    java.io.IOException - if an input or output error is detected when the servlet determines the AuthorizationConstraint
    
    javax.servlet.ServletException - if the request for the dynamic privilege could not be handled
