Gets all the 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);

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>

Protected Overrides Function GetExportsCore (definition As ImportDefinition, atomicComposition As AtomicComposition) As IEnumerable(Of Export)

Parameters

definition: ImportDefinition

The conditions of the Export objects to be returned.

atomicComposition: AtomicComposition

The transactional container for the composition.

Returns

IEnumerable<Export>

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

Remarks

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.
