Class HasautolinkFlatFileLoader<E extends DataObject<E> & NumberedInterface<E> & UniqueidentifiedInterface<E>,F extends DataObject<F> & AutolinkobjectInterface<F,E>>

java.lang.Object

org.openlowcode.server.data.loader.FlatFileLoaderColumn<E>

org.openlowcode.server.data.properties.HasautolinkFlatFileLoader<E,F>

Type Parameters:

E - data object being linked

F - data object of the link

public class HasautolinkFlatFileLoader<E extends DataObject<E> & NumberedInterface<E> & UniqueidentifiedInterface<E>,F extends DataObject<F> & AutolinkobjectInterface<F,E>>
extends FlatFileLoaderColumn<E>

the flat file loader allows to create auto-links provided the object is numbered. It is possible to indicate a series of numbers separated by '|' (pipe character)

HasautolinkFlatFileLoader

public HasautolinkFlatFileLoader(DataObjectDefinition<E> leftobjectdefinition,
                                 DataObjectDefinition<F> linkobjectdefinition,
                                 AutolinkobjectDefinition<F,E> autolinkobjectpropertydef,
                                 NumberedDefinition<E> leftobjectnumberproperty,
                                 boolean deletelinkifnotmentioned,
                                 ConstraintOnAutolinkObject<E>[] constraints)

creates a flat file loader for object with has autolink

Parameters:

leftobjectdefinition - definition of the object being linked

linkobjectdefinition - definition of the link object

autolinkobjectpropertydef - definition of the autolink property on the link

leftobjectnumberproperty - definition of the numbered property on the object

deletelinkifnotmentioned - if true, during the loading, the loader will ensure the list of links is exactly the one provided, i.e. it will delete links that are not mentioned

constraints - constraints for the link
