ISchemaModelGroup Interface
[This feature was only implemented for MSXML 6.0.]
Provides a collection of some combination of the following objects: ISchemaElement, ISchemaModelGroup, and ISchemaAny. The ISchemaModelGroup object is returned from the modelGroups property of the ISchema interface or from the contentModel property of the ISchemaComplexType interface.
The types of items in the collection are specified in the itemType property of the ISchemaItem interface. The following table shows each itemType and its corresponding collection content.
| ISchema.itemType value | Content objects |
|---|---|
| SOMITEM_ALL | A collection of one or more ISchemaElement objects. |
| SOMITEM_CHOICE | A collection of one or more of the following objects: ISchemaElement, ISchemaModelGroup, and ISchemaAny. Each of these objects can occur zero or more times in the collection. |
| SOMITEM_SEQUENCE | A collection of one or more of the following objects: ISchemaElement, ISchemaModelGroup, and ISchemaAny. Each of these objects can occur zero or more times in the collection. |
| SOMITEM_EMPTYPARTICLE | An empty particle which contains a collection of zero particles. ISchemaComplexType.contentModel will return an empty particle when ISchemaComplexType.contentType = SCHEMACONTENTTYPE_EMPTY. |
Properties
| particles | Retrieves the group model, based on the schema item type. This type is retrieved by calling ISchemaItem::itemType. |
JScript Syntax
var oSchemaModelGroups = oSchema.modelGroups
var oSchemaModelGroup = oSchemaModelGroups.item(index);
Parameters
index
A long integer. An index of the item within the collection. The first item is zero.
Visual Basic Syntax
Set oSchemaModelGroups = oSchema.modelGroups
Set oSchemaModelGroup = oSchemaModelGroups.item
(index)
Parameters
index
A long integer. An index of the item within the collection. The first item is zero.
C/C++ Syntax
HRESULT get_modelGroups(ISchemaItemCollection** particles);
HRESULT particles->get_item(long index, ISchemaModelGroup** modelGroup);
Parameters
index [in]
A long integer. An index of the item within the collection. The first item is zero.
particles [out,retval]
An object. The ISchemaItemCollection object of one or more of the following objects: ISchemaElement, ISchemaModelGroup, and ISchemaAny, if any.
