TheStorageMirror<(Of <(<'T>)>)>..::..GetRecords Method (String, Int32, Int32, String, Action<(Of <(<'StoreResponse>)>)>, Boolean, Boolean)

Retrieves records from the StorageMirror's underlying MirrorCache or IStorageService and hands them to the callback. If IsRAMStore or IsCached, the records will be retrieved from the MirrorCache. If IsRAMStore is false, the records will be retrieved from the IStorageService.

Parameters

SQLFilter
Type: String
The "WHERE" clause to filter the records returned. Generally the filter should consist of the form [PropertyName] [Operation] [Value], e.g. FriendlyName = "MyThing"
TopRows
Type: Int32
The maximum number of records to return from the query
PageNumber
Type: Int32
The page number for the query, if the IStorageService supports a paging mechanism. Note that this is only used for retrieval from the IStorageService and not the MirrorCache.
SQLOrder
Type: String
The "ORDER BY" clause to order the records returned. Generally the string should consist of the form [PropertyName] [desc | asc], e.g. cdeCTIM desc
pCallBack
Type: Action<(Of <(<'TheStorageMirror<(Of <(<'T>)>)>..::..StoreResponse>)>)>
The callback method that will be invoked upon error or completed retrieval of records.
LocalCallBackOnly
Type: Boolean
If set to true, no request is sent to a remote StorageService.
InitIfNotInit
Type: Boolean
If the StorageMirror is not ready yet and this value is true, InitializeStore will be called before proceeding with the request.

Return Value

True if the request was successfully made and false otherwise (if the StorageMirror is not ready yet and was not initialized).
