CollectionDef Interface Collection
For a particular collection definition, the interface collection specifies which interface exposes a member of the collection type.
This collection is not attached to the default interface for the CollectionDef Automation object; it is attached to the IInterfaceMember interface. For more information about accessing a member of an interface that is not the default interface, see Accessing Automation Object Members.
Syntax
Set variable = object.Interface(index)
The Interface collection syntax has the following parts.
| Part | Description |
|---|---|
| variable | A variable declared as an InterfaceDef object. Receives the specified interface definition. |
| object | An object expression; evaluates to an object that implements IInterfaceMember as the default interface. |
| index | An integer index that identifies which element in the collection is to be addressed. The valid range is from one to the number of elements in the collection. The number of elements in the collection is specified by object.Interface.Count. For more information, see Selecting Items in a Collection. |
Remarks
The following characteristics are true for this collection.
| Collection characteristic | Value | Description |
|---|---|---|
| Relationship Type | Interface_Has_Members | This is the type of relationship by which all items of the collection are connected to a common source object. |
| Source Is Origin | No | The source object for the collection is not the same as the origin object. |
| Minimum Collection Size | One | The minimum number of items that must be contained in the collection is one. |
| Maximum Collection Size | One | The maximum number of items that can be contained in the collection is one. |
| Sequenced Collection | Yes | As a destination collection, this collection permits an explicitly defined sequence. Collections of origin objects are never sequenced. |
| Deletes Propagated | Yes | Deleting an origin object or a relationship in the collection causes the deletion of a corresponding destination object. |
| Destinations Named | Yes | The relationship type for the collection permits the naming of destination objects. |
| Case-sensitive Names | No | The relationship type for the collection does not permit the use of case-sensitive names for destination objects. |
| Unique Names | Yes | The relationship type for the collection requires that the name of a destination object be unique within the collection of destination objects. This applies to collections whose relationship type permits destination objects to be named. |
