Properties

Kind

Gets the TypeShapeKind that the current shape supports.

public abstract TypeShapeKind Kind { get; }

Property Value

TypeShapeKind

Provider

Gets the provider used to generate this instance.

public required ITypeShapeProvider Provider { get; init; }

Property Value

ITypeShapeProvider

Methods

Accept(TypeShapeVisitor, object?)

Accepts an TypeShapeVisitor for strongly-typed traversal.

public abstract object? Accept(TypeShapeVisitor visitor, object? state = null)

Parameters

visitor TypeShapeVisitor

The visitor to accept.

state object

The state parameter to pass to the underlying visitor.

Returns

object

The object result returned by the visitor.

GetAssociatedTypeFactory(Type)

Gets the factory for a type associated to this property's declared Type, as captured in AssociatedTypes or AssociatedTypes.

public virtual Func<object>? GetAssociatedTypeFactory(Type associatedType)

Parameters

associatedType Type

The associated type (which must be one found in the AssociatedTypes property). If the associated type is a generic type definition, the type arguments used on this shape's Type will be used to close the associated generic type.

Returns

Func<object>

A factory for the associated type, or null if no factory for the associated type is available.

Remarks

ReflectionTypeShapeProvider can produce the factory on demand without any AssociatedTypes, while SourceGenTypeShapeProvider is expected to only produce the factory that was explicitly requested via attribute.

Exceptions

InvalidOperationException

Thrown when this method is called on an instance that does not represent a generic type.
