Methods

ModifyDataCached(DataCacheCookie, ModificationStatement[])

Defines a service operation that, when implemented by a class, updates data in a cached data store using specified modification statements and returns the operation result.

OperationResult<DataCacheModificationResult> ModifyDataCached(DataCacheCookie cookie, ModificationStatement[] dmlStatements)

Parameters

cookie DataCacheCookie

A Root element’s state stored by a specific cache Node.

dmlStatements ModificationStatement[]

An array of data modification statements.

Returns

OperationResult<DataCacheModificationResult>

An OperationResult<DevExpress.Xpo.DB.Helpers.DataCacheModificationResult> denoting the result of the data modifications.

NotifyDirtyTables(DataCacheCookie, params string[])

Defines a service operation that, when implemented by a class, informs a cached data store‘s Root element (DevExpress.Xpo.DB.DataCacheRoot or MSSql2005SqlDependencyCacheRoot) about specific modified tables.

OperationResult<DataCacheResult> NotifyDirtyTables(DataCacheCookie cookie, params string[] dirtyTablesNames)

Parameters

cookie DataCacheCookie

A Root element’s state stored by a specific cache Node.

dirtyTablesNames string[]

An array of table names specifying modified tables.

Returns

OperationResult<DataCacheResult>

An OperationResult<DevExpress.Xpo.DB.Helpers.DataCacheResult> object denoting the operation result.

ProcessCookie(DataCacheCookie)

Defines a service operation that, when implemented by a class, synchronizes table update information with a cached data store‘s Root element (DevExpress.Xpo.DB.DataCacheRoot or MSSql2005SqlDependencyCacheRoot).

OperationResult<DataCacheResult> ProcessCookie(DataCacheCookie cookie)

Parameters

cookie DataCacheCookie

A Root element’s state stored by a specific cache Node.

Returns

OperationResult<DataCacheResult>

An OperationResult<DevExpress.Xpo.DB.Helpers.DataCacheResult> object denoting the operation result.

SelectDataCached(DataCacheCookie, SelectStatement[])

Defines a service operation that, when implemented by a class, fetches data from a cached data store using specified query statements and returns the operation result.

OperationResult<DataCacheSelectDataResult> SelectDataCached(DataCacheCookie cookie, SelectStatement[] selects)

Parameters

cookie DataCacheCookie

A Root element’s state stored by a specific cache Node.

selects SelectStatement[]

An array of query statements.

Returns

OperationResult<DataCacheSelectDataResult>

An OperationResult<DevExpress.Xpo.DB.Helpers.DataCacheSelectDataResult> object denoting the result of the data fetch.

UpdateSchemaCached(DataCacheCookie, DBTable[], bool)

Defines a service operation that, when implemented by a class, updates a cached data store‘s schema according to specified settings.

OperationResult<DataCacheUpdateSchemaResult> UpdateSchemaCached(DataCacheCookie cookie, DBTable[] tables, bool doNotCreateIfFirstTableNotExist)

Parameters

cookie DataCacheCookie

A Root element’s state stored by a specific cache Node.

tables DBTable[]

An array of tables whose structure should be saved in a cached data store.

doNotCreateIfFirstTableNotExist bool

true if the schema should not be created if the table that corresponds to the first item in the tables array doesn’t exist in the cached data store; otherwise, false.

Returns

OperationResult<DataCacheUpdateSchemaResult>

An OperationResult<DevExpress.Xpo.DB.Helpers.DataCacheUpdateSchemaResult> denoting the result of the update operation.
