AggregateExportProvider.GetExportsCore Method (ImportDefinition, AtomicComposition)

 

Gets all the 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 transactional container for the composition.

Return Value

Type: System.Collections.Generic.IEnumerable<Export>

A collection that contains all the exports that match the specified condition.

Implementers should not treat cardinality-related mismatches as errors and are not expected to throw exceptions in those cases.

For example, if the import requests exactly one export and the provider has either no matching exports or more than one, the method should return an empty IEnumerable<T> collection of Export.
