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(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(Set<javax.validation.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.
