Interface IUnionTypeShape<TUnion>

Namespace

PolyType.Abstractions

Assembly

PolyType.dll

Provides a strongly typed shape model for a .NET type encoding a discriminated union.

public interface IUnionTypeShape<TUnion> : ITypeShape<TUnion>, IUnionTypeShape, ITypeShape

Type Parameters

TUnion

The type of the union.

Inherited Members

IUnionTypeShape.UnionCases

ITypeShape.Type

ITypeShape.Kind

ITypeShape.Provider

ITypeShape.AttributeProvider

ITypeShape.Accept(TypeShapeVisitor, object)

ITypeShape.Invoke(ITypeShapeFunc, object)

ITypeShape.GetAssociatedTypeShape(Type)

Remarks

Typically reserved for classes or interfaces that specify derived types via the DerivedTypeShapeAttribute but can also include F# discriminated unions.

Properties

BaseType

Gets the underlying type shape of the union base type.

ITypeShape<TUnion> BaseType { get; }

Property Value

ITypeShape<TUnion>

Remarks

Typically used as the fallback case for values not matching any of the union cases.

Methods

GetGetUnionCaseIndex()

Creates a delegate that computes the union case index for a given value.

Getter<TUnion, int> GetGetUnionCaseIndex()

Returns

Getter<TUnion, int>

A delegate that computes the union case index for a given value.

Remarks

The delegate returns an index pointing to the UnionCases list. It should be noted that the value of the index is distinct from the Tag property.
