Class ValueObjectDescriptor

Namespace: AdCodicem.ValueObjects.Metadata
Assembly: AdCodicem.ValueObjects.Abstractions.dll

Runtime description of a value object type, used by the integrations that only know a .

public sealed class ValueObjectDescriptor

Inheritance​

object ← ValueObjectDescriptor

Inherited Members​

object.Equals(object?), object.Equals(object?, object?), object.GetHashCode(), object.GetType(), object.ReferenceEquals(object?, object?), object.ToString()

Remarks​

The delegates it exposes operate on boxed values, which is acceptable because every one of them is invoked during start-up work — building the EF Core model, generating an OpenAPI document, registering a Dapper type handler — never on a per-request path. Request paths go through the strongly typed generic APIs.

Descriptors are produced by , which is fully generic and therefore free of reflection: the source generator emits one call per value object in a module initializer.

Properties​

Create​

Gets the validating factory. Throws on a rejected value.

public Func<object?, object> Create { get; }

Property Value​

Func<object?, object>

CreateUnchecked​

Gets the trusted-source factory, which performs neither normalization nor validation.

public Func<object?, object> CreateUnchecked { get; }

Property Value​

Func<object?, object>

Format​

Gets the invariant text representation of a boxed value object.

public Func<object, string> Format { get; }

Property Value​

Func<object, string>

GetValue​

Gets the accessor returning the boxed underlying value of a boxed value object.

public Func<object, object?> GetValue { get; }

Property Value​

Func<object, object?>

Schema​

Gets the declarative constraints of the value object.

public ValueObjectSchema Schema { get; }

Property Value​

ValueObjectSchema

TryCreate​

Gets the non-throwing validating factory.

public BoxedTryCreate TryCreate { get; }

Property Value​

BoxedTryCreate

TryParse​

Gets the non-throwing text parser.

public BoxedTryParse TryParse { get; }

Property Value​

BoxedTryParse

ValueObjectType​

Gets the value object type.

public Type ValueObjectType { get; }

Property Value​

Type

ValueType​

Gets the underlying value type.

public Type ValueType { get; }

Property Value​

Methods​

For<TSelf, TValue>(ValueObjectSchema)​

Builds a descriptor for a value object, resolving every operation statically.

public static ValueObjectDescriptor For<TSelf, TValue>(ValueObjectSchema schema) where TSelf : struct, IValueObject<TSelf, TValue>

Parameters​

schema ValueObjectSchema

Declarative constraints of the value object.

Returns​

ValueObjectDescriptor

The descriptor.

Type Parameters​

TSelf

Value object type.

TValue

Underlying value type.
