- Method Detail
  - onFailure
```
public void onFailure(ServerFailure error)
```
    Receives general failure notifications. The default implementation looks at ServerFailure.isFatal(), and throws a runtime exception with the failure object's error message if it is true.
    
    Parameters:
    
    error - a ServerFailure instance
  - onSuccess
```
public abstract void onSuccess(V response)
```
    Called when a Request has been successfully executed on the server.
    
    Parameters:
    
    response - a response of type V
  - onViolation
```
@Deprecated
public void onViolation(java.util.Set<Violation> errors)
```
    Deprecated.
    Use onConstraintViolation(Set) instead
    
    Called if an object sent to the server could not be validated. The default implementation calls onFailure(ServerFailure) if errors is not empty.
    
    Parameters:
    
    errors - a Set of Violation instances
  - onConstraintViolation
```
public void onConstraintViolation(java.util.Set<ConstraintViolation<?>> violations)
```
    Called if an object sent to the server could not be validated. The default implementation calls onViolation(Set), converting the ConstraintViolation objects to the deprecated Violation type.
    
    Parameters:
    
    violations - a Set of ConstraintViolation instances
