2.1.14 EntityContainer

  • [アーティクル]

EntityContainer is conceptually similar to a database or data source. It groups EntitySet, AssociationSet, and FunctionImport child elements that represent a data source.

The following is an example of the EntityContainer element.

   <EntityContainer Name="Model1Container" >
     <EntitySet Name="CustomerSet" EntityType="Model1.Customer" />
     <EntitySet Name="OrderSet" EntityType="Model1.Order" />
     <AssociationSet Name="CustomerOrder" Association="Model1.CustomerOrder">
       <End Role="Customer" EntitySet="CustomerSet" />
       <End Role="Order" EntitySet="OrderSet" />
     </AssociationSet>
   </EntityContainer>

The following rules apply to the EntityContainer element:

  • EntityContainer MUST have a Name attribute defined that is of type SimpleIdentifier.

  • EntityContainer can define an Extends attribute, which, if present, refers to another EntityContainer in scope by name.

  • EntityContainer elements that extend another EntityContainer inherit all of the extended EntitySet, AssociationSet, and FunctionImport child elements from that EntityContainer.

  • EntityContainer can contain a maximum of one Documentation element.

  • EntityContainer can contain any number of AnnotationAttribute attributes. The full names of the AnnotationAttribute attributes cannot collide.

  • EntityContainer can contain any number of FunctionImport, EntitySet, and AssociationSet elements, which can be defined in any order.

  • FunctionImport, EntitySet, and AssociationSet names within an EntityContainer cannot collide.

  • If present, the Documentation child element MUST precede FunctionImport, EntitySet, and AssociationSet child elements.

  • In CSDL 2.0 and CSDL 3.0, EntityContainer can contain any number of AnnotationElement elements.

  • In CSDL 3.0, EntityContainer can contain any number of ValueAnnotation elements.

  • In the sequence of child elements under EntityContainer, AnnotationElement follows all other elements.

All child elements are to appear in the order indicated. For all child elements within a given choice, the child elements can be ordered arbitrarily.
