CatalogExportProvider.GetExportsCore(ImportDefinition, AtomicComposition) CatalogExportProvider.GetExportsCore(ImportDefinition, AtomicComposition) CatalogExportProvider.GetExportsCore(ImportDefinition, AtomicComposition) Method

Definition

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

protected:
 override System::Collections::Generic::IEnumerable<System::ComponentModel::Composition::Primitives::Export ^> ^ GetExportsCore(System::ComponentModel::Composition::Primitives::ImportDefinition ^ definition, System::ComponentModel::Composition::Hosting::AtomicComposition ^ atomicComposition);
protected override System.Collections.Generic.IEnumerable<System.ComponentModel.Composition.Primitives.Export> GetExportsCore (System.ComponentModel.Composition.Primitives.ImportDefinition definition, System.ComponentModel.Composition.Hosting.AtomicComposition atomicComposition);
override this.GetExportsCore : System.ComponentModel.Composition.Primitives.ImportDefinition * System.ComponentModel.Composition.Hosting.AtomicComposition -> seq<System.ComponentModel.Composition.Primitives.Export>

Parameters

definition
ImportDefinition ImportDefinition ImportDefinition

The conditions of the Export objects to be returned.

atomicComposition
AtomicComposition AtomicComposition AtomicComposition

The composition transaction to use, or null to disable transactional composition.

Returns

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

Remarks

Implementers 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.
