BindableProperty.CreateDefaultValueDelegate<TDeclarer,TPropertyType> Delegate

Definition

Represents a strongly-typed delegate that creates a default value for a bindable property.

public delegate TPropertyType BindableProperty.CreateDefaultValueDelegate<in TDeclarer,out TPropertyType>(TDeclarer bindable);
type BindableProperty.CreateDefaultValueDelegate<'Declarer, 'PropertyType> = delegate of 'Declarer -> 'PropertyType
Public Delegate Function BindableProperty.CreateDefaultValueDelegate(Of In TDeclarer, Out TPropertyType)(bindable As TDeclarer) As TPropertyType 

Type Parameters

TDeclarer

The type of the declaring object.

This type parameter is contravariant. That is, you can use either the type you specified or any type that is less derived. For more information about covariance and contravariance, see Covariance and Contravariance in Generics.
TPropertyType

The type of the property value.

This type parameter is covariant. That is, you can use either the type you specified or any type that is more derived. For more information about covariance and contravariance, see Covariance and Contravariance in Generics.

Parameters

bindable
TDeclarer

The declaring object instance that owns the property.

Return Value

TPropertyType

The default value for the property.

Remarks

This strongly-typed delegate is useful for creating unique default instances for reference types, avoiding shared references between different bindable object instances.
