SimpleFieldSchema Interface

A simple, shallow representation of a schema for a field.

This API is provided as an alpha preview and may change without notice.

To use, import via @fluidframework/tree/alpha.

For more information about our API support guarantees, see here.

Sealed

This type is "sealed," meaning that code outside of the library defining it should not implement or extend it. Future versions of this type may add members or make typing of readonly members more specific.

Signature

/** @sealed */
export interface SimpleFieldSchema<Type extends SchemaType = SchemaType>

Type Parameters

ParameterConstraintDefaultDescription
TypeSchemaTypeSchemaType

Remarks

This definition is incomplete, and references child types by identifiers. To be useful, this generally needs to be used as a part of a complete SimpleTreeSchema, which contains backing definitions for each referenced identifier.

Property Details

kind

The kind of tree field.

This API is provided as an alpha preview and may change without notice.

For more information about our API support guarantees, see here.

Signature

readonly kind: FieldKind;

Type: FieldKind

metadata

Metadata for this field schema, see FieldSchemaMetadata.

This API is provided as an alpha preview and may change without notice.

For more information about our API support guarantees, see here.

Signature

readonly metadata: FieldSchemaMetadata & (Type extends SchemaType.View ? unknown : {
readonly custom?: undefined;
readonly description?: undefined;
});

Type: FieldSchemaMetadata & (Type extends SchemaType.View ? unknown : { readonly custom?: undefined; readonly description?: undefined; })

Remarks

As this is the non-persisted portion of the metadata, it is forced to store only undefined in the SchemaType.Stored case.

persistedMetadata

Persisted metadata for this field schema.

This API is provided as an alpha preview and may change without notice.

For more information about our API support guarantees, see here.

Signature

readonly persistedMetadata?: JsonCompatibleReadOnlyObject | undefined;

Type: JsonCompatibleReadOnlyObject | undefined

Remarks

Like persistedMetadata but for fields. Set via persistedMetadata.

simpleAllowedTypes

Information about the allowed types under this field.

This API is provided as an alpha preview and may change without notice.

For more information about our API support guarantees, see here.

Signature

readonly simpleAllowedTypes: ReadonlyMap<string, SimpleAllowedTypeAttributes<Type>>;

Type: ReadonlyMap<string, SimpleAllowedTypeAttributes<Type>>

Remarks

Refers to the types by identifier. A SimpleTreeSchema is needed to resolve these identifiers to their schema definitions.
