supports

public boolean supports(Class clazz)

Specified by:

supports in interface Validator

setDomainClass

public void setDomainClass(GrailsDomainClass domainClass)

Parameters:

domainClass - The domainClass to set.

getDomainClass

public GrailsDomainClass getDomainClass()

public void setMessageSource(MessageSource messageSource)

Parameters:

messageSource - The messageSource to set.

validate

public void validate(Object obj,
                     Errors errors,
                     boolean cascade)

Description copied from interface: CascadingValidator

An extended version of the validate(errors,obj) method that takes an additional argument specifying whether the Validator should cascade into associations or not

Specified by:

validate in interface CascadingValidator

Parameters:

obj - The Object to validate

errors - The Spring Errors instance

cascade - True if validation should cascade into associations

See Also:

CascadingValidator.validate(Object, org.springframework.validation.Errors, boolean)

postValidate

protected void postValidate(Object obj,
                            Errors errors)

Subclasses can overrite to provide custom handling of the errors object post validation

Parameters:

obj - The object to validate

errors - The Errors object

validate

public void validate(Object obj,
                     Errors errors)

Specified by:

validate in interface Validator

See Also:

Validator.validate(Object, org.springframework.validation.Errors)

cascadeToAssociativeProperty

protected void cascadeToAssociativeProperty(Errors errors,
                                            BeanWrapper bean,
                                            GrailsDomainClassProperty persistentProperty)

Cascades validation onto an associative property maybe a one-to-many, one-to-one or many-to-one relationship

Parameters:

errors - The Errors instnace

bean - The original bean

persistentProperty - The associative property

cascadeValidationToMany

protected void cascadeValidationToMany(Errors errors,
                                       BeanWrapper bean,
                                       GrailsDomainClassProperty persistentProperty,
                                       String propertyName)

Cascades validation to a one-to-many type relationship. Normally a collection such as a List or Set each element in the association will also be validated

Parameters:

errors - The Errors instance

bean - The original BeanWrapper

persistentProperty - An association whose isOneToMeny() method returns true

propertyName - The name of the property

cascadeValidationToOne

protected void cascadeValidationToOne(Errors errors,
                                      BeanWrapper bean,
                                      Object associatedObject,
                                      GrailsDomainClassProperty persistentProperty,
                                      String propertyName)

Cascades validation to a one-to-one or many-to-one property

Parameters:

errors - The Errors instance

bean - The original BeanWrapper

associatedObject - The associated object's current value

persistentProperty - The GrailsDomainClassProperty instance

propertyName - The name of the property

getAssociatedDomainClassFromApplication

setGrailsApplication

public void setGrailsApplication(GrailsApplication grailsApplication)

Description copied from interface: GrailsApplicationAware

This method is called by the ApplicationContext that loads the Grails application. The GrailsApplication instance that represents the loaded Grails application is injected.

Specified by:

setGrailsApplication in interface GrailsApplicationAware

Parameters:

grailsApplication - the GrailsApplication object that represents this Grails application
