Parameters

cmdUpdateFinished: Type: LinkarClientOperationAsyncCallbackString
Return type in asynchronous methods.
credentialsOptions: Type: LinkarCommonCredentialsOptions
Object that defines the necessary data to access to the Linkar Server: Username, Password, EntryPoint, Language, FreeText.
filename: Type: SystemString
File name where you are going to write.
recordIds: Type: SystemString
It's the records codes list you want to register, separated by the Record Separator character (30).
records: Type: SystemString
Are the records you want to update, separated by the Record Separator character (30).
updateOptions: Type: LinkarCommonUpdateOptions
Object that defines the different writing options of the Function: optimisticLockControl, readAfter, calculated, dictionaries, conversion, formatSpec, originalRecords.
originalRecords (Optional): Type: SystemString
Are the original records that you want to update for Optimistic Block verifications, separated by the Record Separator character (30).
inputStringType (Optional): Type: LinkarCommonDATAFORMAT_TYPE
Indicates in what format you wish to send the resultant writing data: MV, XML or JSON.
outputStringType (Optional): Type: LinkarCommonDATAFORMATCRU_TYPE
Indicates in what format you want to receive the data resulting from the Read, New, Update and Select operations: MV, XML, XML_DICT, XML_SCH, JSON, JSON_DICT or JSON_SCH.
customVars (Optional): Type: SystemString
It's a free text that will travel until the database to make the admin being able to manage additional behaviours in the standard routine SUB.LK.MAIN.CONTROL.CUSTOM. This routine will be called if the argument has content.
receiveTimeout (Optional): Type: SystemInt32
It's the maximum time in seconds that the client will keep waiting the answer by the server. By default -1 (wait indefinitely).
