CollectionConverter

public class DefaultCollectionConverterImpl
extends AbstractCollectionConverterImpl

Default Collection Mapping/convertion implementation. This collection mapping strategy maps a collection under an extra JCR node (specify by the jcrName in the CollectionDescriptor). It is usefull when the node type "nt:unstructured" is applied to the collection elements. By this way, it is possible to distinguish the collection elements from the other main object fields. If the collection element class contains an id (see the ID FieldDescriptor definition), this id value is used to build the collection element node. Otherwise, the element node name is a simple constant. Example - without an id attribute: /test (Main object containing the collection field ) /mycollection (extra node used to store the entire collection) /collection-element (node used to store the first collection element) /item-prop .... /collection-element (node used to store the second collection element) ... Example - with an id attribute: /test (Main object containing the collection field ) /mycollection (extra node used to store the entire collection) /aValue (id value assigned to the first element) /item-prop .... /anotherValue (id value assigned to the first element) ...
