Namespace: System.ComponentModel.Composition.Hosting
Assembly: System.ComponentModel.Composition (in System.ComponentModel.Composition.dll)
Syntax
'Declaration
Protected Overrides Function GetExportsCore ( _
definition As ImportDefinition, _
atomicComposition As AtomicComposition _
) As IEnumerable(Of Export)
protected override IEnumerable<Export> GetExportsCore(
ImportDefinition definition,
AtomicComposition atomicComposition
)
Parameters
- definition
Type: System.ComponentModel.Composition.Primitives.ImportDefinition
The ImportDefinition that defines the conditions of the Export to get.
- atomicComposition
Type: System.ComponentModel.Composition.Hosting.AtomicComposition
The composition transaction to use, or nulla null reference (Nothing in Visual Basic) to disable transactional composition.
Return Value
Type: System.Collections.Generic.IEnumerable<Export>
A collection of all exports in this provider that match the specified conditions.
Remarks
Implementations should not treat cardinality-related mismatches as errors and should not throw exceptions for cardinality-related mismatches. For example, if the import requests exactly one export and the provider has no matching exports or more than one, the GetExportsCore method should return an empty IEnumerable<T> collection of Export objects.
