OData vocabulary annotation interface and methods.

Annotations, labeled elements, and properties can contain elements.

A collection can contain records and simple values. In the code example, a collection is created for an annotation. The collection contains a simple value (string):


DATA:

      lo_ann_target TYPE REF TO /iwbep/if_mgw_vocan_ann_target,  " Vocabulary Annotation Target

      lo_annotation TYPE REF TO /iwbep/if_mgw_vocan_annotation,  " Vocabulary Annotation

      lo_simp_value TYPE REF TO /iwbep/if_mgw_vocan_simple_val,   " Vocabulary Annotation Simple Value

      lo_collection TYPE REF TO /iwbep/if_mgw_vocan_collection.   " Vocabulary Annotation Collection

 

lo_ann_target = vocab_anno_model->create_annotations_target( 'Products' ).

lo_annotation = lo_ann_target->create_annotation( iv_term = 'Org.OData.Core.V1.OptimisticConcurrencyControl' ).

lo_collection = lo_annotation->create_collection( ).

lo_simp_value = lo_collection->create_simple_value( ).

lo_simp_value->set_string( 'image/jpeg' ).

In the metadata document, this is reflected as follows:

<Annotations xmlns=="http://docs.oasis-open.org/odata/ns/edm" Target="Products">
<Annotation Term="Org.OData.Core.V1.OptimisticConcurrencyControl">
<Collection>
<String>image/jpeg</String>
</Collection>
</Annotation>
