The \<objectService>.cancelSync function cancels an in progress object service sync operation. The operation fails if the task syncing is already finished, throws an error, or does not support the Cancel operation.

Volt MX Iris (JavaScript)

Note:

• Not supported for Mobile Web and Desktop Web channels.

Signature

VMXObjSvc.cancelSync(Options, onSuccess, onFailure)

Parameters

Parameter	Type	Description	Required
Options	JSON	Reserved for future use, so the parameter is insignificant. But, the developer must pass some value such as null or { }.	Yes
onSuccess	Function	The JavaScript function to be executed when cancellation is successful.	Yes
onFailure	Function	The JavaScript function to be executed when cancellation fails.	Yes

Return Type

void

Example

var syncObjectSvc = new voltmx.sdk.VMXObjSvc("Organization");

// define Sync options
var syncOptions = {};
syncOptions.downloadBatchSize = 100;
syncOptions.uploadBatchSize = 200;
syncOptions.getSyncStats = true;

// Start Sync asynchronously
syncObjectSvc.startSync(syncOptions,
function(res) {
alert("ObjectService sync successful");
},
function(err) {
alert("ObjectService sync failed with error: " + JSON.stringify(err));
},
function(progressCallback) {
alert("ObjectService sync progress event received");
});

// Now attempt to Cancel Sync// passing an empty map for options parameter
syncObjectSvc.cancelSync({},
function(res) {
alert("ObjectService sync cancellation successful");
},
function(err) {
alert("ObjectService sync failed with error : " + JSON.stringify(err));
});

Android (Java)

Signature

public void cancelSync(HashMap<String, Object> options, final VMXCallback syncCancellationCallback)

Parameters

Parameter	Type	Description	Required
options	HashMap	Reserved for future use, so the parameter is insignificant. But, the developer must pass some value such as null or new HashMap().	Yes
syncCancellationCallback	VMXCallback	Application implements onSuccess and onFailure methods of VMXCallback interface.	Yes

Return Type

void

Example

VMXObjSvc syncObjectSvc = new VMXObjSvc("Organization");

// Define Sync options
HashMap < String, Object > syncOptions = new HashMap < String, Object > ();
syncOptions.put("downloadBatchSize", "100");
syncOptions.put("uploadBatchSize", "200");
syncOptions.put("getSyncStats"
"true");

// Start Sync asynchronously
syncObjectSvc.startSync(syncOptions,
new VMXCallback() {
@Override
public void onSuccess(Object object) {
Log.d("ObjectServiceSync", "ObjectService sync successful");
}

        @Override
        public void onFailure(Object error) {
            Log.e("ObjectServiceSync", "ObjectService sync failed with error: " + error);
        }
    },
    new VMXProgressCallback() {
        @Override
        public void onProgress(Object object) {
            Log.d("ObjectServiceSync", "ObjectService sync progress event received");
        }
    });

// Now attempt to Cancel Sync
// passing an empty HashMap for options parameter
syncObjectSvc.cancelSync(new HashMap < String, Object > (),
new VMXCallback() {
@Override
public void onSuccess(Object object) {
Log.d("ObjectServiceSync Cancellation", "ObjectService sync cancellation successful");
}

        @Override
        public void onFailure(Object error) {
            Log.e("ObjectServiceSync Cancellation", "ObjectService sync cancellation failed with error: " + error);
        }
    });

iOS (Objective C)

Signature

(void)cancelSync:(NSDictionary \*)options
onSuccess:(VMXSuccessCompletionHandler)onSuccess
onFailure:(VMXFailureCompletionHandler)onFailure

Parameters

Parameter	Type	Description	Required
onSuccess	VMXSuccessCompletionHandler	The method called after a successful cancellation.	Yes
onFailure	VMXFailureCompletionHandler	The method called after the cancellation fails.	Yes

Return Type
