public sealed class FirestoreEnumNameConverter<T> : IFirestoreConverter<T> where T : struct, EnumCustom converter which uses enum value names instead of integer values as the Firestore representation. This converter is not used by default; it must be configured in the same way as any other custom converter.
Implements
IFirestoreConverter<T>Namespace
Google.Cloud.FirestoreAssembly
Google.Cloud.Firestore.dll
Type Parameter | |
|---|---|
| Name | Description |
T | The enum type to convert |
Remarks
Currently this is always case-sensitive, with no customization of the names used. In future releases we may introduce further ways to configure this converter, but the default behavior will remain the same.
When the same enum value has multiple names, no guarantee is made about which one is returned, although both are accepted for conversion back to enum values. You are strongly encouraged not to use multiple names for the same value.
