Interface FieldPersistenceProvider

All Superinterfaces:

org.springframework.core.Ordered

All Known Implementing Classes:

AbstractFieldPersistenceProvider, AbstractMoneyFieldPersistenceProvider, BasicFieldPersistenceProvider, DefaultFieldPersistenceProvider, FieldPersistenceProviderAdapter, MapFieldPersistenceProvider, MediaFieldPersistenceProvider, MoneyFieldPersistenceProvider, RuleFieldPersistenceProvider

public interface FieldPersistenceProvider
extends org.springframework.core.Ordered

Classes implementing this interface are capable of handling persistence related events for fields whose values are being requested or set for the admin. This includes any special translations or transformations required to get from the string representation in the admin back to the field on a Hibernate entity - and the reverse. Providers are typically added in response to new admin presentation annotation support that requires special persistence behavior. Note, FieldPersistenceProvider instances are part of BasicPersistenceModule, and therefore relate to variations on persistence of basic fields. Implementers should generally extend FieldPersistenceProviderAdapter.

Method Detail

populateValue

FieldProviderResponse populateValue(PopulateValueRequest populateValueRequest,
                                    Serializable instance)

Set the property value on the target object. Implementations should translate the requestedValue field from the request and set on the instance parameter. You are basically taking the string value submitted by the admin application and converting it into the format required to set on the target field of instance (which should be a JPA managed entity). Used during admin create and update events.

Parameters:

populateValueRequest - contains the requested value and support classes.

instance - the persistence entity instance on which to set the value harvested from the request

Returns:

whether or not the implementation handled the persistence request

extractValue

FieldProviderResponse extractValue(ExtractValueRequest extractValueRequest,
                                   Property property)

Retrieve the property value from the requestedValue field from the request. Implementations should translate the requestedValue and set on the property parameter. The requestedValue is the field value taken from the JPA managed entity instance. You are taking this field value and converting it into a string representation appropriate for the property instance parameter. Used during admin fetch events.

Parameters:

extractValueRequest - contains the requested value and support classes.

property - the property for the admin that will contain the information harvested from the persistence value

Returns:

whether or not the implementation handled the persistence request

addSearchMapping

FieldProviderResponse addSearchMapping(AddSearchMappingRequest addSearchMappingRequest,
                                       List<FilterMapping> filterMappings)

Add FilterMapping instances. The FilterMappings are used by the system to refine the fetch criteria used to retrieve lists of records for the admin. The requestedCto contains filters requested from the admin and is generally used to drive the added FilterMapping instances.

Parameters:

addSearchMappingRequest - contains the requested cto and support classes.

filterMappings - filter criteria should be added here. It is used to generate the final search criteria.

Returns:

whether or not the implementation handled the persistence request

filterProperties

FieldProviderResponse filterProperties(AddFilterPropertiesRequest addFilterPropertiesRequest,
                                       Map<String,FieldMetadata> properties)

Filter the list of properties posted by the admin during and add or update. This is the property list immediately before persistence is attempted. Properties may be altered, removed or added.

Parameters:

addFilterPropertiesRequest - contains the Entity instance.

properties - the collection of properties to filter

Returns:

whether or not the implementation handled the persistence request
