ImportDefinition Constructors

Definition

Namespace:

System.ComponentModel.Composition.Primitives

Assembly:

System.ComponentModel.Composition.dll

Package:

System.ComponentModel.Composition v9.0.0-preview.3.24172.9

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

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.

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

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);

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.

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

Source:

ImportDefinition.cs

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.

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, System::Collections::Generic::IDictionary<System::String ^, System::Object ^> ^ metadata);

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, System.Collections.Generic.IDictionary<string,object?>? metadata);

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.Collections.Generic.IDictionary<string, obj> -> 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, metadata As IDictionary(Of String, Object))

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.

metadata

IDictionary<String,Object>

The metadata associated with the import.
