Class AbstractNuitonValidatorContext<O,V,E>

java.lang.Object

org.nuiton.validator.bean.AbstractNuitonValidatorContext<O,V,E>

Type Parameters:

O - type of bean to validate

V - type of bean validator used

E - type of event to create

Direct Known Subclasses:

BeanListValidator.NuitonValidatorContext, SimpleBeanValidator.NuitonValidatorContext

public abstract class AbstractNuitonValidatorContext<O,V,E>
extends Object

Defines a context of validation used for a single bean. SimpleBeanValidator will then used one of this object and BeanListValidator as many as it contains beans. This object box a NuitonValidator to get validation state each time a higher validator requires it. It also offers the way to create events (merge logic
