CollectionConverter

public class NTCollectionConverterImpl
extends AbstractCollectionConverterImpl

Collection Mapping/convertion based on node type. This collection mapping strategy maps the collection elements into subnodes based on the same node types. There are 3 constraints in this collection converter : 1/ this is not possible to have 2 different collections in the main object which are used the same jcr node type for their elements. 2/ this is not possible to make a distinction between an empty collection and an null collection. 3/ Map are not supported. If the collection element class contains an id (see the FieldDescriptor definition), this id value is used to build the collection element node name. Otherwise, the element node name is a simple constant (collection-element) Example - without an id attribute: /test (Main object containing the collection field ) /collection-element (node used to store the first collection element) /item-prop .... /collection-element (node used to store the second collection element) ... Each "collection-element" nodes have the same jcr node type Example - with an id attribute: /test (Main object containing the collection field ) /aValue (id value assigned to the first element) /item-prop .... /anotherValue (id value assigned to the first element) ... Each collection element nodes have the same jcr node type
