Initializes a new instance of the ImportDefinition class.

Overloads

ImportDefinition()	Initializes a new instance of the ImportDefinition class.
ImportDefinition(Expression<Func<ExportDefinition,Boolean>>, String, ImportCardinality, Boolean, Boolean)	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.
ImportDefinition(Expression<Func<ExportDefinition,Boolean>>, String, ImportCardinality, Boolean, Boolean, IDictionary<String,Object>)	Initializes a new instance of the ImportDefinition class with the specified constraint, contract name, cardinality, and metadata, and indicates whether the import definition is recomposable or a prerequisite.

ImportDefinition()

Source:: ImportDefinition.cs

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

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.ImportDefinition

Public 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

ArgumentNullException

constraint is null.

ArgumentException

cardinality is not one of the values of ImportCardinality.

Applies to

ImportDefinition(Expression<Func<ExportDefinition,Boolean>>, String, ImportCardinality, Boolean, Boolean, IDictionary<String,Object>)

Source:: ImportDefinition.cs

Source:: ImportDefinition.cs

Source:: ImportDefinition.cs

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.
