Class Summary

Class	Description
AttributesMapper<A extends Attributes<A,V>,V>	Specialized/Convenient wrapper Mapper for mapping Attributes. This specialized because Attributes and Attribute have an encapsulated relation which requires awareness of the Attributes interface.
AttributesSetter<A extends Attributes<A,V>,V>	Convenient EntityFieldSetter to set Attribute value into Attributes type entity.
AuthorizableETLMeta<PARAM_META>	Authorizable FacetMeta
AuthorizableTransformer	If a Transformation process has Authorization needs.
BastardProductFilter<P extends Product>	During ETL it is possible that a USER may apply an UPDATE instead on an INSERT on some records This can technically lead to a product not updating or deriving parent info if parent info is not updated during Updates and gives rise to Bastard Products (ones without any parents) The default implementation of this Filter simply rejects any such records to ensure they don't get into the system.
CacheLookup	A Spring based transformer Implement a Cache wrapper over any Transformer
CaseInsensitiveListTransformer	Take any Collection and convert to CaseInsensitiveList
CategoryListTransformer	Load all non-leaf nodes and return List of String[] {Product.getName, Display name with 'escaped space' padding prefixed, Product.getHierarchy}
ColorListTransformer	Pick out unique values from a List of raw Color strings and present a List of String[] {raw COLOR VALUE, Display Name for Color using WordUtils.capitalize(String)}
ContentFacetRevert	Reverts a AbstractContentFacet.setValue(String) as input, from a ContentFacet for the same ContentDescriber but of status = ContentFacetRevert.statusFrom
ContentNameConsumer<C extends AbstractContent>	In some projects for content pages they do not want _ to appear in Name, hence links.
DaoWrapperTransformer<T>	A Transformer capable of returning an object for an id and updating the object if the input to it is the object itself.
DeleteRelatedEntitiesJPATransformer	Related entities can grow in relation to the core entity. (JPA) This Transformer provides a visitor via injection to the core logic, that can allow manipulating the number of entities that are effected in a delete operation.
DeleteRelatedEntitiesMySQLTransformer	Related entities can grow in relation to the core entity. (MySQL) This Transformer provides a visitor via injection to the core logic, that can allow manipulating the number of entities that are effected in a delete operation.
EnsureAttributeExistsTransformer	Extends EnsureAccessorExistsTransformer Additionally if any of the instances in the access chain are Attribute type then it sets the Entity and Attribute name to the Attribute.
EnsureEntityManagerSetTransformer	Update an UpdatableContext with EntityManager to ensure if it contains a transient field, that is set back.
EntityBabyPersistTransformer<E>	This Transformer will ensure that the entity is persisted and return back the passed in input.
EntityManagerProviderTransformer	Provide Access to EntityManager With a lot of classes being Serializable they cannot hold the EntityManager and may need access.
EntityParamQueryLookup	Lookup using a Query over ModelObject Parses the {QueryCacheLookup.getQuery() string for parameters usage like ":param1" and then tries to fetch the value from the model object and substitute it automatically into the Query.
EntityPersistTransformer<E>	Persist an Entity and return the Persisted Entity using the auto wired EntityManager. Additionally this Transformer is capable of: Collecting Exceptions in EntityPersistTransformer.exceptions and EntityPersistTransformer.messages if EntityPersistTransformer.failFast is false Persisting the entity under a TransactionDefinition, if provided via EntityPersistTransformer.setTransactionDef(TransactionDefinition).
EntityResourceUploadActionTransformer<T>	Accepts a context Map from DocumentManagerPanel.FileUploadForm.postUploadCustomAction() Will return a list of Strings, each corresponding to a path modified or null if no change.
EntityUpdateResUploadActionTransformer<T>
ExcelRowToProductTransformer<P extends Product>	Converts an Excel Row to a Product This Process is EventAwareProcess and Is Transactional aware
ExistingProductLookup<T extends Product>	Check to see if a Product already exists, and if so load it based on various other settings provided by this class.
FileToEntityLookup<T>	Based on a File, identify which Product it related to.
FileToPathTransformer	Derive the path for products.
FileToProductLookup<P extends Product>	Based on a File, identify which Product it related to TODO: Add Unit test case for Partial match scenarios
FileToProductsTransformer<P extends Product>	Allow to update an existing Entitie(s) i.e.
GetNewHierarcyLookup<T extends Product>	Given a parent HierarchialDomainObject, derive next Hierarchy code under its immediate parent
InputStringToSizeTransformer	Convert a raw String input to Size object.
ModeAwareProductPersistTransformer<P extends Product>	Persist a Product/Product(s) and return the Persisted Entity
MultiCategoryLookup<T extends HierarchialDomainObject>	Searches for a category to match a criteria defined by MultiCategoryLookup.queryTransformer.
ObjectToRowReverseTransformer<T>	A AbstractReverseTupleToEntityTransformer that exports to an Array of Objects. One can use UsesIntermediateObject (available via intermediateObjects Map), that refer to the input entity as "entity" and to the tuple being written as "tuple"
PageToTemplate	Derive a Template from its PageIdentifier
PermaLinkTransformer	For a Given input String (content) (typically but not restricted to a AbstractAttribute.getValue() or even AbstractAttribute, it allows content to refer to Page URL's dynamically so that if the URL changes then automatically it will apply the change in URL to avoid broken links.
ProductCategoryLookup<P extends Product>	Lookup Wrapping for com.neurosys.products.lookup.ProductCategoryLookup so it can be used in Chains and Mappers easily.
ProductCategoryTransformer<P extends Product>	Converts a Product to a Category A category has following main characteristics: Has Children : The adapter will insert a dummy record if it has no children already
ProductMultiCategoryLookup<T extends Product>	Deprecated This was the original CatgegoryLookup, however its query is sloppy and specific.
ProductNameTransformer<T extends Product>	Product Name has some restrictions like being unique etc, it cannot be always what is supplied raw; so it is combines with the Product.getProductCode() to ensure it is unique.
ProductPersistTransformer<P extends Product>	Persist a Product/Product(s) and return the Persisted Entity
ProductURLGeneratorTransformer<P extends Product>	A Transformer that accepts Product Id/sku or any identifier that ProductURLGeneratorTransformer.productFetch accepts or Product and produces a Link for it. The ProductURLGeneratorTransformer.idParamName part of the URL is encoded in UTF-8 TODO: Add Unit test case
QueryCacheLookup<T>	Deprecated @see CacheLookup
QueryResultArrayToEntityTransformer<ENTITY>	An ObjectArrayToEntityTransformer that also provides a QueryResultArrayToEntityTransformer.replaceEntityString(String, String) to prepare the actual Query to return the result array in the expected format as defined by AbstractEntityTransformer.getColumnFieldMapping()
RelatedEntityPersistTransformer<E extends Identifiable<?>>	This Transformer will ensure that the entity is persisted and return back the passed in input.
RelatedEntityUpdateTransformer<T>	Takes in an entity, and for it copies, its attributes using an EntityFieldsCopyTransformer to all its related model entities
RelWebPathToAbsoluteTransformer
SearchJPAQueryBuilderTransformer	A Search Query Transformer to map Input in a panel to query terms to construct the database JPA search query.
SizeFitToCodeTransformer	Convert a SizeFit to its code
SizeToOutputStringTransformer	Convert a Size object to a String
SizeToStringTransformer	Convert a Size object to a String
SizeTypeInitMapperTransformer	Create a Size sub-type based on field name and value.
SpringCacheTransformer	Uses a CacheManager to fetch data from a Cache.
StringToSizeTransformer	Convert a raw String input to Size object.
SubTypeInitMapperTransformer<ENTITY>	AbstractEntityTransformers like QueryResultArrayToEntityTransformer; can use polymorphic instances like Size for AbstractEntityTransformer.setNestedObjectInitMap(java.util.Map). While initializing an instance the sub-type needs to be known dynamically based on the key or field name and its value.
TransactionalTransformer	Initiates a Transactional on the inner wrapped Transformer
UserToJson<U extends AbstractUser>	Marshal User to JSON TODO: Add unit test case
ValueToAttributeTransformer<A extends Attribute>	Creates an Attribute for the input value.
VelocityContentTransformer	For a Given input String (content) (or even a AbstractAttribute.getValue() or AbstractAttribute), which is assumed to be a velocity script.
VelocityEntityUpdateResUploadActionTransformer<T>	This implementation is a velocity based template constructor.
