VMXFoundry.OfflineObjects.reset

Offline objects reset function resets device database to the initial stage of the sync environment. Once the reset is successful, all data is removed from the database but the database table structure is preserved.

Note: Reset requires network connection, and it fetches the latest Volt MX Foundry app schema.

Volt MX Iris (JavaScript)

Signature

VMXFoundry.OfflineObjects.reset(options, successCallback, failureCallback)

Input Parameters

Parameter	Type	Description	Required
options	JSON	Reset options such as device database, encryption passphrase and so on.	Yes
successCallback	Function	The function is invoked on successful reset.	Yes
failureCallback	Function	The function is invoked on an error with the cause of failure as an argument.	Yes

Setup Options

Option	Type	Description	Required
deviceDbEncryptionKey	String	Encryption passphrase must be a string with at least six characters long. For more information, refer Offline Objects Getting Started Guide. Note: Not applicable for Mobile Web and Desktop Web channels.	No
treatBooleanFieldValuesAsNumeric	Boolean	If the treatBooleanFieldValuesAsNumeric key is set to false, all the boolean field values are converted to boolean type (true or false) during upload session or on reading records from local device database. When the option is set to true, fallbacks to default implementation (uploading and reading boolean field values as numeric). By default, the key is set to True. Note: Supported for iOS and Android from V8 SP4 Fix Pack 102 onwards.	No

Return Type

void

Error Codes

Error Code	Error Text
106	Claims token is unavailable.

Example

function successCallback(status) {
voltmx.print("Application reset successful");
}

function failureCallback(error) {
voltmx.print("Application reset failed with error:" + error.code);
}

//Decrypt and re encrypt the device database
Var options = {
"deviceDbENcryptionKey": "myencryptionpa$$phrase1"};
VMXFoundry.OfflineObjects.reset(options,successCallback, failureCallback);

HashMap < String, object > options = new HashMap < String, object > ();
options.put("deviceDbEncryptionKey", "myencryptionpa$$phrase1");
appSync.reset(options, new VMXCallback() {
@Override
public void onSuccess(Object object) {
Log.d("Application Reset", "Application reset successful");

    }

    @Override
    public void onFailure(Object error) {
        OfflineObjectsException e = (OfflineObjectsException) error;
        Log.e("Application Reset", "Application reset failed with error :" + e.getMessage());

    }
