PgRangeTypeAttribute

Namespace: Ankus

Assembly: Ankus.Runtime.dll

Associates a mapped scalar bound with an existing PostgreSQL range type.

[AttributeUsage(AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Enum, AllowMultiple = true, Inherited = false)]
public sealed class PgRangeTypeAttribute : Attribute

Apply this attribute to a value type carrying PgDatumType. The scalar reader and writer convert finite bounds of PgRange<T>; PostgreSQL validates and canonicalizes the range itself. This declaration registers conversion and SQL metadata; it does not create a SQL range type. An extension-owned range requires a PgSqlTypeProvider for its exact PgRange<T> managed identity, independently of the scalar’s provider. External ranges require an explicit schema. Generic default declarations apply to finite selected scalar constructions. An explicit managed-type declaration selects one closed scalar construction and takes precedence over its optional default. Multidimensional arrays use one PgArray<PgRange<T>> container with the declared range identity.

PgRangeTypeAttribute(Type, string)

Associates one exact closed construction of the annotated scalar type with a SQL range type.

public PgRangeTypeAttribute(Type managedType, string name)

Parameters:

managedType — Type

The closed scalar bound type whose definition carries this attribute.

name — string

The exact unquoted PostgreSQL range type identifier.

Properties

ManagedType

Gets the exact closed scalar bound identity, or null for the annotated type’s default range mapping.

public Type? ManagedType { get; }

Value: Type

Name

Gets the exact catalog range type identifier.

public string Name { get; }

Value: string

Origin

Gets or sets whether this extension supplies the range or an external schema already contains it.

public PgTypeOrigin Origin { get; set; }

Value: PgTypeOrigin

Schema

Gets or sets the range’s fixed schema. External ranges require an explicit schema.

public string? Schema { get; set; }

Value: string
