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);

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 composition transaction to use, or null to disable transactional 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 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.
