Method Detail

processValidation

public void processValidation(javax.faces.context.FacesContext facesContext,
                              javax.faces.component.UIComponent uiComponent,
                              MetaDataEntry metaDataEntry,
                              Object convertedObject)
                       throws javax.faces.validator.ValidatorException

Description copied from class: AbstractValidationStrategy

Validates the given value based on the given meta-data entry. The method throws a ValidatorException if a violation is detected

Specified by:

processValidation in class AbstractValidationStrategy

Parameters:

facesContext - The JSF Context

uiComponent - The JSF component that contained the value entered by the user.

metaDataEntry - The data holder which stores the meta-data and some information where the meta-data was around.

convertedObject - Converted object of the user entered value.

Throws:

javax.faces.validator.ValidatorException - When violation of the validation rules occurs.

getValidationErrorMsgKey

protected String getValidationErrorMsgKey(Annotation annotation)

Description copied from class: AbstractAnnotationValidationStrategy

Returns the key for the message that needs to be resolved for the violation-message.

Specified by:

getValidationErrorMsgKey in class AbstractAnnotationValidationStrategy

Parameters:

annotation - The annotation associated with the ValidationStrategy.

Returns:

The key of the error message.

getErrorMessageDetail

protected String getErrorMessageDetail(Annotation annotation)

Description copied from class: AbstractAnnotationValidationStrategy

Returns the error message (the detailed message) provided by the given constraint. The message is determined by using the AbstractAnnotationValidationStrategy.getValidationErrorMsgKey(A) method for obtaining the message-/key which then is resolved by the method resolveMessage. When the key isn't found, the resulting exception is just logged but not propagated. So the detail message isn't required and null is returned instead.

Overrides:

getErrorMessageDetail in class AbstractAnnotationValidationStrategy

Parameters:

annotation - The annotation associated with the ValidationStrategy.

Returns:

The error message used in the detail part of the FacesMessage or null.

resolveMessage

protected String resolveMessage(String key)

Description copied from class: AbstractAnnotationValidationStrategy

Uses the given message key to resolve the actual message in the correct language. The current UIViewRoot provides the target locale. When a MessageResolver is available, it is used to resolve the message. Otherwise the default rules are taken to define the MessageResolver. ExtValUtils.getMessageResolverForValidationStrategy( org.apache.myfaces.extensions.validator.core.validation.strategy.ValidationStrategy)

Overrides:

resolveMessage in class AbstractAnnotationValidationStrategy

Parameters:

key - key of the error message that needs to be resolved.

Returns:

Resolved message.

processAfterValidatorException

protected boolean processAfterValidatorException(javax.faces.context.FacesContext facesContext,
                                                 javax.faces.component.UIComponent uiComponent,
                                                 MetaDataEntry metaDataEntry,
                                                 Object convertedObject,
                                                 javax.faces.validator.ValidatorException e)

Description copied from class: AbstractAnnotationValidationStrategy

Executes the registered ValidationExceptionInterceptor to process the validation exception. Adds the label of the component to the MetaDataEntry.

Overrides:

processAfterValidatorException in class AbstractAnnotationValidationStrategy

Parameters:

facesContext - The JSF Context

uiComponent - The JSF component that contained the value entered by the user.

metaDataEntry - The data holder which stores the meta-data and some information where the meta-data was around.

convertedObject - Converted object of the user entered value.

e - The validation exception that occurred.

Returns:

should return true when you like to have the ValidatorException thrown by the ExtValUtils#tryToThrowValidatorExceptionForComponent method. ExtValUtils.tryToThrowValidatorExceptionForComponent(javax.faces.component.UIComponent, javax.faces.application.FacesMessage, java.lang.Throwable)
