org.broadleafcommerce.openadmin.server.service.persistence.module.provider.AbstractFieldPersistenceProvider

org.broadleafcommerce.openadmin.server.service.persistence.module.provider.FieldPersistenceProviderAdapter

org.broadleafcommerce.openadmin.server.service.persistence.module.provider.RuleFieldPersistenceProvider

All Implemented Interfaces:

FieldPersistenceProvider, org.springframework.core.Ordered

@Component(value="blRuleFieldPersistenceProvider")
 @Scope(value="prototype")
public class RuleFieldPersistenceProvider
extends FieldPersistenceProviderAdapter

Provides persistence (read/write) behavior for rule builder fields. This includes two types: Rule with quantity, and simple rule. OfferImpl#targetItemCriteria and OfferImpl#offerMatchRules are examples of each, respectively. This class is only compatible with quantity-based rules modeled using a Set and @OneToMany, and with simple rules modeled using a Map and @OneToMany.

canHandlePersistence

protected boolean canHandlePersistence(PopulateValueRequest populateValueRequest,
                                       Serializable instance)

canHandleExtraction

protected boolean canHandleExtraction(ExtractValueRequest extractValueRequest,
                                      Property property)

populateValue

public MetadataProviderResponse populateValue(PopulateValueRequest populateValueRequest,
                                              Serializable instance)
                                       throws PersistenceException

Description copied from interface: FieldPersistenceProvider

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.

Specified by:

populateValue in interface FieldPersistenceProvider

Overrides:

populateValue in class FieldPersistenceProviderAdapter

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

Throws:

PersistenceException

extractValue

public MetadataProviderResponse extractValue(ExtractValueRequest extractValueRequest,
                                             Property property)
                                      throws PersistenceException

Description copied from interface: FieldPersistenceProvider

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.

Specified by:

extractValue in interface FieldPersistenceProvider

Overrides:

extractValue in class FieldPersistenceProviderAdapter

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

Throws:

PersistenceException

filterProperties

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

Description copied from interface: FieldPersistenceProvider

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.

Specified by:

filterProperties in interface FieldPersistenceProvider

Overrides:

filterProperties in class FieldPersistenceProviderAdapter

Parameters:

addFilterPropertiesRequest - contains the Entity instance.

properties - the collection of properties to filter

Returns:

whether or not the implementation handled the persistence request

extractParent

protected Object extractParent(PopulateValueRequest populateValueRequest,

                        throws IllegalAccessException,
                               FieldNotAvailableException

This method is intended to find the object that the field is supposed to be populated on. Typically, this is the instance itself, but sometimes it may be a property of an object this instance relates to. This method ignores parent candidates that implement Embeddable as the proper parent for these fields is the object itself and not the embedded object.

Parameters:

populateValueRequest - the PopulateValueRequest

instance - the Object we are populating field values on

Returns:

the proper parent for the PopulateValueRequest

Throws:

IllegalAccessException

FieldNotAvailableException

recursivelyExtractParent

protected Object recursivelyExtractParent(PopulateValueRequest populateValueRequest,
                                          Serializable instance)
                                   throws FieldNotAvailableException,
                                          IllegalAccessException

This method is responsible for recursively tracing the properties parents to find the correct parent to apply the field update to.

Parameters:

populateValueRequest - the populate value request

instance - the entity that to populate a field value on

Returns:

the proper parent or original instance if no closer parent is found

Throws:

FieldNotAvailableException

IllegalAccessException

parseParentProperty

protected String parseParentProperty(String propertyName)

isEmbeddable

protected boolean isEmbeddable(Class<?> clazz)

This method is responsible for determining whether the class is embeddable. If it is we don't want to check if the entity manager contains the instance since embeddables are not entities.

Parameters:

clazz - the parent class of the populate value request

Returns:

whether the class is embeddable
