Uses of ContextAware in com.neurosys.etl.common

Subinterfaces of ContextAware in com.neurosys.etl.common

Modifier and Type	Interface and Description
interface	UsesIntermediateObject<CONTEXT> A Transformer, Predicate, Lookup or Chain that uses an IntermediateResultMapperBehaviors result(s). A process that recognized this type of instance will #setIntermediateResults(Map)

Uses of ContextAware in com.neurosys.etl.common.transformers

Classes in com.neurosys.etl.common.transformers that implement ContextAware

Modifier and Type	Class and Description
class	EnsureAccessorExistsTransformer This Transformer does not apply any Transformation on the input itself (unless there is no intermediate object), however for the intermediate object passed it ensures for an accessor chain like entity.attributes.attrib1 the necessary instances like "attributes" and "attrib1" exist else while setting one will get NullPointerExceptions.
class	EntityChainAccessTransformer A convenient way to access (read only) an entity; and derive the accessor object or value using any of the following methods: Dot chaining convention like "a.b.c".
class	EntityFieldsCopyTransformer<T,F> Copies fields from an Entity to another (accepts an array or Iterable of 2 objects FROM and a Collection of TO). If the input is not an array type, it assumes it as the INPUT object and generates a clone with the required copy.
class	MergeCols During an ETL transformation merge multiple columns in a tuple, into a Map OR JSON (if MergeCols.transformer is a JSONTransformer.
class	ObjectFieldValueTransformer Extracts the Field value of an Object.
class	ThreadLocalTransformer Passes the UsesIntermediateObjectImpl.determineInput(Object) into a ThreadLocal variable
class	UsesIntermediateObjectImpl<CONTEXT> Basic implementation for UsesIntermediateObject
class	UsesIntermediateObjectWrapper<T extends org.apache.commons.collections.Transformer> Allow a processor; Transformer, Lookup to be wrapped in this to allow for re-suing existing processors instead of extending UsesIntermediateObjectImpl for every new use case.

Uses of ContextAware in com.neurosys.modules.etl

Classes in com.neurosys.modules.etl that implement ContextAware

Modifier and Type	Class and Description
class	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.
class	GetNewHierarcyLookup<T extends Product> Given a parent HierarchialDomainObject, derive next Hierarchy code under its immediate parent
class	MultiCategoryLookup<T extends HierarchialDomainObject> Searches for a category to match a criteria defined by MultiCategoryLookup.queryTransformer.
class	ProductMultiCategoryLookup<T extends Product> Deprecated. This was the original CatgegoryLookup, however its query is sloppy and specific. Simply use MultiCategoryLookup with a Tramsformer defined to run the Query
class	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.
