Channel copy

With Méthode Swing it’s possible to add custom manipulation to the content of a channel copy after his creation.

Registration of a custom manipulation

To register a custom manipulation, use the following namespace

eidosmedia.webclient.extensions.channelCopy

and its function

register( options )

Table 1. Method information
Method	`register`
Parameter	Required `{object} options` - An object containing a function that will be invoked to perform the custom manipulation.
Returns	`{undefined}` undefined

The following is a very simple registration for a custom manipulation.

(function() {


    eidosmedia.webclient.extensions.channelCopy.register(function( data, callback ) {

            // Save the current content of the channel copy
            var xmlElaborated = data.xmlContent;

            try {

                /**
                 * Save the current content of the channel copy. This variable will be used to make some changes to the current content
                 */
                var xmlContent = data.xmlContent;

                /**
                 * Save information about the current channel copy. For example the channel name
                 */
                var copyInfo = data;

                /**
                 * Perform some simple manipulation. In our case add only a new attribute
                 */
                var xml = $.parseXML(xmlContent);
                var $xml = $(xml);
                var $doc = $xml.find('doc');
                $doc.attr('newattr', 'newvalue');

                /**
                 * Serialize the new xml content
                 */
                var serializer = new XMLSerializer();
                var preValue = xmlElaborated.slice(0, xmlElaborated.indexOf('<doc'));
                var result = serializer.serializeToString($doc[0]);

                /**
                 * Save the new xml content
                 */
                xmlElaborated = preValue + result;

                /**
                 * notify a callback if specified
                 */
                if (callback) {
                    callback(xmlElaborated);
                }

            } catch (ex) {
                console.log("Channel copy custom manipulation exception caught", ex);

                if (callback) {
                    callback(xmlElaborated);
                }
            }
    });

})();

The function must be have two parameters. The first one contains info about xml content and the channel object info. The second one it’s a callback that must be invoked after the custom manipulation. Wrap all the custom manipulation with a try…catch block otherwise the normal process of the channel copy creation will be not performed.

After the custom manipulation the system will perform a validation check of the new content. If the check goes wrong the channel copy will be created with the original content and the user will be notified
