ImportDefinition()
- Source:
- ImportDefinition.cs
- Source:
- ImportDefinition.cs
Initializes a new instance of the ImportDefinition class.
protected:
ImportDefinition();protected ImportDefinition ();Protected Sub New ()Remarks
Derived types that call this constructor must override the Constraint property, and optionally, the Cardinality, IsPrerequisite and IsRecomposable properties.
Applies to
ImportDefinition(Expression<Func<ExportDefinition,Boolean>>, String, ImportCardinality, Boolean, Boolean)
- Source:
- ImportDefinition.cs
- Source:
- ImportDefinition.cs
Initializes a new instance of the ImportDefinition class with the specified constraint, contract name, and cardinality, and indicates whether the import definition is recomposable or a prerequisite.
public:
ImportDefinition(System::Linq::Expressions::Expression<Func<System::ComponentModel::Composition::Primitives::ExportDefinition ^, bool> ^> ^ constraint, System::String ^ contractName, System::ComponentModel::Composition::Primitives::ImportCardinality cardinality, bool isRecomposable, bool isPrerequisite);public ImportDefinition (System.Linq.Expressions.Expression<Func<System.ComponentModel.Composition.Primitives.ExportDefinition,bool>> constraint, string? contractName, System.ComponentModel.Composition.Primitives.ImportCardinality cardinality, bool isRecomposable, bool isPrerequisite);public ImportDefinition (System.Linq.Expressions.Expression<Func<System.ComponentModel.Composition.Primitives.ExportDefinition,bool>> constraint, string contractName, System.ComponentModel.Composition.Primitives.ImportCardinality cardinality, bool isRecomposable, bool isPrerequisite);new System.ComponentModel.Composition.Primitives.ImportDefinition : System.Linq.Expressions.Expression<Func<System.ComponentModel.Composition.Primitives.ExportDefinition, bool>> * string * System.ComponentModel.Composition.Primitives.ImportCardinality * bool * bool -> System.ComponentModel.Composition.Primitives.ImportDefinitionPublic Sub New (constraint As Expression(Of Func(Of ExportDefinition, Boolean)), contractName As String, cardinality As ImportCardinality, isRecomposable As Boolean, isPrerequisite As Boolean)Parameters
- constraint
- Expression<Func<ExportDefinition,Boolean>>
An expression that contains a Func<T,TResult> object that defines the conditions an Export must match to satisfy the import definition.
- contractName
- String
The contract name.
- cardinality
- ImportCardinality
One of the enumeration values that indicates the cardinality of the Export objects required by the import definition.
- isRecomposable
- Boolean
true to specify that the import definition can be satisfied multiple times throughout the lifetime of a ComposablePart object; otherwise, false.
- isPrerequisite
- Boolean
true to specify that the import definition must be satisfied before a ComposablePart can start producing exported objects; otherwise, false.
Exceptions
constraint is null.
cardinality is not one of the values of ImportCardinality.
