CatalogExportProvider.GetExportsCore Method

Returns all exports that match the conditions of the specified import.

Namespace:  System.ComponentModel.Composition.Hosting
Assembly:  System.ComponentModel.Composition (in System.ComponentModel.Composition.dll)

protected override IEnumerable<Export> GetExportsCore(
	ImportDefinition definition,
	AtomicComposition atomicComposition
)

Parameters

definition
Type: System.ComponentModel.Composition.Primitives.ImportDefinition
The conditions of the Export objects to be returned.
atomicComposition
Type: System.ComponentModel.Composition.Hosting.AtomicComposition
The composition transaction to use, or null to disable transactional composition.

Return Value

Type: System.Collections.Generic.IEnumerable<Export>
A collection that contains all the exports that match the specified condition.

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 either no matching exports or more than one, the GetExportsCore method should return an empty IEnumerable<T> collection of Export objects.
