public:
virtual System::Collections::Generic::IEnumerable<Tuple<System::ComponentModel::Composition::Primitives::ComposablePartDefinition ^, System::ComponentModel::Composition::Primitives::ExportDefinition ^> ^> ^ GetExports(System::ComponentModel::Composition::Primitives::ImportDefinition ^ definition);
public virtual System.Collections.Generic.IEnumerable<Tuple<System.ComponentModel.Composition.Primitives.ComposablePartDefinition,System.ComponentModel.Composition.Primitives.ExportDefinition>> GetExports (System.ComponentModel.Composition.Primitives.ImportDefinition definition);
abstract member GetExports : System.ComponentModel.Composition.Primitives.ImportDefinition -> seq<System.ComponentModel.Composition.Primitives.ComposablePartDefinition * System.ComponentModel.Composition.Primitives.ExportDefinition>
override this.GetExports : System.ComponentModel.Composition.Primitives.ImportDefinition -> seq<System.ComponentModel.Composition.Primitives.ComposablePartDefinition * System.ComponentModel.Composition.Primitives.ExportDefinition>
Public Overridable Function GetExports (definition As ImportDefinition) As IEnumerable(Of Tuple(Of ComposablePartDefinition, ExportDefinition))
Parameters
- definition
- ImportDefinition
The conditions of the ExportDefinition objects to be returned.
Returns
A collection of Tuple<T1,T2> containing the ExportDefinition objects and their associated ComposablePartDefinition objects for objects that match the constraint specified by definition
.
Exceptions
The ComposablePartCatalog object has been disposed of.
definition
is null
.
Remarks
Overrides of this method should never return null
. If no ExportDefinition matches the conditions defined by definition
, return an empty IEnumerable<T> object.
