DevExpress.Xpo.DB Namespace

Contains classes that handle operations on a data store.

Expanded Classes

  Class Description
Public class AccessConnectionProvider Implements data-aware operations for working with MS Access databases.
Public class AccessConnectionProviderMultiUserThreadSafe Implements an MS Access connection provider that can be used in multi-user and multi-threaded applications.
Public class CachedDataStoreClient A Cached Data Store provider (an ICachedDataStore implementation) for client applications transferring data via WCF.
Public class CachedDataStoreClientAsync A Cached Data Store provider that client applications can use to asynchronously work with the data source via WCF.
Public class CachedDataStoreClientAsyncBase<TContractType>
Public class CachedDataStoreService The base class for WCF services providing access to data via cached data stores (objects implementing the ICachedDataStore interface).
Public class DataStoreClient A data store provider (an IDataStore implementation) for client applications transferring data via WCF.
Public class DataStoreClientAsync A data store provider that client applications can use to asynchronously work with the data source via WCF.
Public class DataStoreService The base class for WCF services providing access to data directly via data store providers (IDataStore implementors).
Public class FirebirdConnectionProvider Implements data-aware operations for working with a Firebird database.
Public class InMemoryDataStore Stores persistent objects in memory. Intended for testing environment.
Public class MSSqlConnectionProvider Implements data-aware operations for working with an MS SQL Server or MS SQL Azure database.
Public class OleDBConnectionProvider Implements the base functionality for providers that connect to OLE DB data sources.
Public class OperationResult The result of an operation performed by the DataStoreService, CachedDataStoreService, or SerializableObjectLayerService.
Public class OperationResult<T> The result of an operation performed by the DataStoreService, CachedDataStoreService, or SerializableObjectLayerService.
Public class PostgreSqlConnectionProvider Implements data-aware operations for working with a PostgreSQL database.
Public class SerializableObjectLayerProxyBase The base class for DevExpress.Xpo.SerializableObjectLayer proxies.
Public class SerializableObjectLayerService The base class for WCF services providing access to data via distributed object access layers (DevExpress.Xpo.ISerializableObjectLayer implementors).
Public class SerializableObjectLayerServiceClient A distributed Object Access Layer (an DevExpress.Xpo.ISerializableObjectLayer implementation) for client applications transferring data via WCF.
Public class ServiceBase The base class for XPO WCF services.
Public class ServiceExceptionEventArgs Arguments, passed to the GlobalServiceExceptionThrown and ServiceExceptionThrown events.

Expanded Interfaces

  Interface Description
Public interface ICachedDataStoreService Defines a WCF service contract to access data stored in cached data stores (objects implementing the ICachedDataStore interface).
