Properties
IncludeMethods
Gets the binding flags that determine what method or event shapes should be included in the type shape.
public MethodShapeFlags IncludeMethods { get; init; }Property Value
Remarks
This property controls how the Methods and Events collections will be populated. If left unspecified, only methods annotated with MethodShapeAttribute or EventShapeAttribute will be included.
This type can only be used to control inclusion of public methods in the shape models. Non-public methods can only be included individually via explicit attribute annotations.
InferClosedTypePolymorphism
Gets a value indicating whether compiler-provided closed-class metadata should be used to infer a polymorphic type hierarchy.
public bool InferClosedTypePolymorphism { get; init; }Property Value
Remarks
When enabled, the annotated type must be a C# closed class and its shape is a union, including when the hierarchy contains no cases. Closed subclasses are expanded recursively; only terminal, non-closed subclasses are registered. Configuration on intermediate closed subclasses applies to their own shapes and does not affect inference for the annotated type.
Explicit DerivedTypeShapeAttribute registrations take precedence over KnownTypeAttribute registrations, which take precedence over inference. Inferred cases preserve compiler metadata order and receive implicit tags. Those tags are not stable across changes to the hierarchy.
This setting cannot be combined with a Marshaler or an explicitly requested Kind other than Union.
Kind
Gets the kind that should be generated for the annotated type.
public TypeShapeKind Kind { get; init; }Property Value
Remarks
Passing None will result in the generation of an IObjectTypeShape that does not contain any properties or constructors.
Exceptions
- ArgumentOutOfRangeException
The specified value is not a valid TypeShapeKind.
Marshaler
Gets a type implementing an IMarshaler<TSource, TTarget> to a surrogate type.
public Type? Marshaler { get; init; }Property Value
Remarks
The type should have a parameterless constructor and must implement IMarshaler<TSource, TTarget> where either of the two generic types should match the annotated type.
Types that specify a Marshaler will be of shape ISurrogateTypeShape.
