protected void	initComponent(javax.faces.context.FacesContext facesContext, javax.faces.component.UIComponent uiComponent) Initialize the component based on the meta-data which is provided by the referenced property.
protected boolean	interpretEmptyStringValuesAsNull() Uses a config parameter (javax.faces.INTERPRET_EMPTY_STRING_SUBMITTED_VALUES_AS_NULL) which was introduced by JSF 2 for converting empty strings to null.
protected boolean	isRequiredInitializationSupported() In case of required initialization it's needed for some use-cases to reset the (required-)state of the components.

Method Detail

isRequiredInitializationSupported

protected boolean isRequiredInitializationSupported()

Description copied from class: AbstractValidationInterceptor

In case of required initialization it's needed for some use-cases to reset the (required-)state of the components. Such a reset is just needed if required initialization is activated.

Overrides:

isRequiredInitializationSupported in class AbstractValidationInterceptor

Returns:

true if required initialization is supported by the current implementation, false otherwise

initComponent

protected void initComponent(javax.faces.context.FacesContext facesContext,
                             javax.faces.component.UIComponent uiComponent)

Description copied from class: AbstractValidationInterceptor

Initialize the component based on the meta-data which is provided by the referenced property.

Specified by:

initComponent in class AbstractValidationInterceptor

Parameters:

facesContext - The JSF Context

uiComponent - The component which is processed

getTransformedMetaDataFor

protected Map<String,Object> getTransformedMetaDataFor(javax.faces.context.FacesContext facesContext,
                                                       javax.faces.component.UIComponent uiComponent)

processValidation

protected void processValidation(javax.faces.context.FacesContext facesContext,
                                 javax.faces.component.UIComponent uiComponent,
                                 Object convertedObject)

Description copied from class: AbstractValidationInterceptor

A concrete implementation has to perform the actual validation of the value.

Specified by:

processValidation in class AbstractValidationInterceptor

Parameters:

facesContext - The JSF Context

uiComponent - The UIComponent which is processed.

convertedObject - The (adjusted) converted value.

getComponentMetaDataExtractor

protected MetaDataExtractor getComponentMetaDataExtractor(Map<String,Object> properties)

Description copied from class: AbstractValidationInterceptor

Implementations must return the MetaDataExtractor that will perform the extraction of the meta data from the component. The component itself is present in the properties map (it might influence the type of the returned MetaDataExtractor.

Specified by:

getComponentMetaDataExtractor in class AbstractValidationInterceptor

Parameters:

properties - Properties that can be used to determine the extractor which is returned.

Returns:

The MetaDataExtractor used for performing the xtraction of the meta data from the component.

processFieldValidation

protected void processFieldValidation(javax.faces.context.FacesContext facesContext,
                                      javax.faces.component.UIComponent uiComponent,
                                      Object convertedObject,
                                      PropertyInformation propertyInformation)

isValidationStrategyCompatibleWithValue

protected boolean isValidationStrategyCompatibleWithValue(ValidationStrategy validationStrategy,
                                                          Object value,
                                                          MetaDataEntry entry)

interpretEmptyStringValuesAsNull

protected boolean interpretEmptyStringValuesAsNull()

Description copied from class: AbstractValidationInterceptor

Uses a config parameter (javax.faces.INTERPRET_EMPTY_STRING_SUBMITTED_VALUES_AS_NULL) which was introduced by JSF 2 for converting empty strings to null.

Overrides:

interpretEmptyStringValuesAsNull in class AbstractValidationInterceptor

Returns:

true if an empty string should be replaced with null (for the validation process), false otherwise

recordProcessedInformation

protected boolean recordProcessedInformation()

Description copied from class: AbstractValidationInterceptor

Signals if the converted value should be stored e.g. for the cross-validation process.

Overrides:

recordProcessedInformation in class AbstractValidationInterceptor

Returns:

true if the converted value should be recorded, false otherwise
