  - getCurrentInstance
```
public static Verifier getCurrentInstance()
```
    Returns:

  - setCurrentInstance
```
public static void setCurrentInstance(Verifier verifier)
```
    Set the Verifier for this thread (typically the same thread that is used to bootstrap the application).
    
    Parameters:
    
    verifier - the Verifier for this web application
  - isApplicationValid
```
public boolean isApplicationValid()
```
    Returns:
    
    true if no messages were queued by the validation process
  - getMessages
```
public List<String> getMessages()
```
    Returns:
    
    a List of all failures found
  - validateObject
```
public void validateObject(Verifier.ObjectType type,
                           String className,
                           Class<?> assignableTo)
```
    Validate the specified faces object by:
    
    Ensure the class can be found and loaded
    Ensure the object has a public, no-argument constructor
    Ensure the object is an instance of the class represented by assignableTo
    If any of these tests fail, queue a message to be displayed at a later point in time.
    Parameters:
    
    type - The type of Faces object we're validating
    
    className - the class name of the Faces object we're validating
    
    assignableTo - the type we expect className to either implement or extend
