Interface Validator

All Known Implementing Classes:

AbstractValidator, ValidatorImpl

public interface Validator

Basic validation interface which defines the contract for event based validation. Event values are defined in LifeCycleEvent.

Method Summary

<T> ValidationException	validate(T arg0, int event) Validates a given instance
<T> ValidationException	validateProperty(T arg0, String property, int event) Validates a property of a given instance
<T> ValidationException	validateValue(Class<T> arg0, String arg1, Object arg2, int event) Validates a value based upon the constraints applied to a given class attribute.
<T> boolean	validating(T arg0, int event) Method for determining whether validation is active for the given type and event.

Method Detail

validate

Type Parameters:

T - The instance type to base validation upon

Parameters:

arg0 - The class of type T to validate

arg1 - The property to validate

arg2 - The property value to validate

event - The event id
