ExportFactory(Of T) Class
Creates new instances of a part that provides the specified export.
Assembly: System.ComponentModel.Composition.Initialization (in System.ComponentModel.Composition.Initialization.dll)
Thetype exposes the following members.
|CreateExport||Creates an instance of the factory's export.|
|Equals(Object)||Determines whether the specified Object is equal to the current Object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Serves as a hash function for a particular type. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
When using an indirect reference to a part via a Lazy(Of T) object, the Value property always returns a reference to the same object. In some circumstances, this is not desirable, and you would like each reference to result in the creation of a new object. is designed for those scenarios.
can be used in a similar fashion to Lazy(Of T) when creating attributed parts. That is, an import contract defined on with a generic parameter of T will match an export defined on T. For example, the follow export and import match:
<Export()> Public myData As String = "Example Data." <Import()> Public Property theData As ExportFactory(Of String)
The value returned from the CreateExport method is an ExportLifetimeContext(Of T) object, which has two pieces. The Value property provide access to the created part. Calling the Dispose method of the ExportLifetimeContext(Of T) object will clean up the created part and all of its dependencies, allowing its lifetime to be managed without reference to the container that created it.
