Inherited properties
| Name | Type | Inherited from | Description |
|---|---|---|---|
| _cacheName Protected Static | string | CloudSqlite.DbAccess<ViewStore.ViewDb, ViewStore.ReadMethods, ViewStoreRpc.Writer> | |
| _cloudDb Protected | ViewStore.ViewDb | CloudSqlite.DbAccess<ViewStore.ViewDb, ViewStore.ReadMethods, ViewStoreRpc.Writer> | |
| _container Protected | CloudSqlite.CloudContainer | CloudSqlite.DbAccess<ViewStore.ViewDb, ViewStore.ReadMethods, ViewStoreRpc.Writer> | |
| container Accessor ReadOnly | CloudSqlite.CloudContainer | CloudSqlite.DbAccess<ViewStore.ViewDb, ViewStore.ReadMethods, ViewStoreRpc.Writer> | the container for this DbAccess. It is automatically connected to the CloudCache whenever it is accessed. |
| dbName Readonly | string | CloudSqlite.DbAccess<ViewStore.ViewDb, ViewStore.ReadMethods, ViewStoreRpc.Writer> | The name of the database within the cloud container. |
| lockParams Readonly | CloudSqlite.ObtainLockParams | CloudSqlite.DbAccess<ViewStore.ViewDb, ViewStore.ReadMethods, ViewStoreRpc.Writer> | Parameters for obtaining the write lock for this container. |
| reader Accessor ReadOnly | PickMethods<ReadMethods> | CloudSqlite.DbAccess<ViewStore.ViewDb, ViewStore.ReadMethods, ViewStoreRpc.Writer> | A Proxy Object to call a synchronous readonly method on the database controlled by this DbAccess.Whenever a method is called through this Proxy, it will first ensure that the database is opened for at least read access. |
| sasToken Accessor | string | CloudSqlite.DbAccess<ViewStore.ViewDb, ViewStore.ReadMethods, ViewStoreRpc.Writer> | The token that grants access to the cloud container for this DbAccess. If it does not grant write permissions, all write operations will fail. It should be refreshed (via a timer) before it expires. |
| writeLocker Accessor ReadOnly | PickAsyncMethods<WriteMethods> | CloudSqlite.DbAccess<ViewStore.ViewDb, ViewStore.ReadMethods, ViewStoreRpc.Writer> | A Proxy Object to call a writeable async method on the cloud database controlled by this DbAccess.Whenever a method is called through this Proxy, it will: - attempt to acquire the write lock on the container - open the database for write - call the method - close the database - upload changes - release the write lock. |
