<object>.markForUpload

The <object>.markForUpload API selects the changes made to the records and sent to the server. If the markForUpload flag is not enabled, the changes made are deferred from uploading to the server until marked for upload using specific markForUpload APIs.

The markForUpload flag is set to true, by default.

<object>.markForUpload(options, successCallback, failureCallback)

Parameters

Parameter	Type	Description	Required
options	JSON	A dictionary containing mandatory key primaryKeys which contains the PK (column name and value). In case of a composite PK, the dictionary will contain multiple key-value pairs.	Yes
successCallback	Function	The function is invoked when the changes are successfully uploaded to the server.	Yes
failureCallback	Function	The function is invoked when the changes are deferred from uploading to the server.	Yes

Options Keys

Keys	Type	Description	Required
primaryKeys	JSON	Specify the primary keys of the record to select a query. Key Name: primaryKeys and value is a dictionary of primary keys.	Yes

Return Type

void

Example

var category = new voltmx.sdk.VMXObj("CATEGORY");
var options = {};
var primaryKeys["CategoryID"] = "1";
options["primaryKeys"] = primaryKeys;
//mark the deferred record for upload with primary key 1
category.markForUpload(options, successCallback, failureCallback);

function successCallback() {
    voltmx.print("markForUpload successful");
}

function errorCallback(error) {
    voltmx.print("markForUpload failed " + error.code);
}

<VMXObj>.markForUpload(final HashMap<String, Object> options, final VMXCallback callback)

Parameters

Parameter	Type	Description	Required
options	HashMap<String, Object>	key: primaryKeys. Value: HashMap<String, Object>: Pass a hashmap of primary keys and its value. HashMap containing PK (column name and value). In case of a composite PK, the dictionary will contain multiple key-value pairs.	Yes
callback	VMXCallback	Takes onSuccess and onFailure methods.	Yes

Options Keys

Keys	Type	Description	Required
primaryKeys	HashMap<String, Object>	Specify the primary keys of the record for the select query. Key Name: primaryKeys and respective values to populate primaryKeys map.	Yes

Return Type

void

Examples

VMXObj category = new VMXObj("CATEGORY");
HashMap < String, Object > options = new HashMap < String, Object > ();
HashMap < String, Object > primaryKeys = new HashMap < String, Object > ();
primaryKeys.put("CATEGORY_ID", "1");
options.put("primaryKeys", primaryKeys);
//mark the deferred record for upload with primary key 1
category.markForUpload(options, new VMXCallback() {
        @Override
        public void onSuccess(Object object) {
            Log.d("Object markforupload", "Object markforupload Successful ");
