Edit several elements on a page with only one RQL command

All update methods in the style of set*Value(“templateElementName”, “new value”) immediately triggers an RQL command.

If you do so for several page elements the performance would be quite poor. To address this, jRQL offers a way to combine updates on several page elements into only one RQL command.

See the following lines how to achieve this better performance updating several elements on one page.

// 1. step – prepare the page
Page currentPg = project.getPageById(“4711”);

// 2. step – remember new page element values only
currentPg.addSetOptionListValue(“templateElementName”, “value”);
currentPg.addSetStandardFieldDateValue(“templateElementName”, new ReddotDate());
currentPg.addSetStandardFieldNumericValue(“templateElementName”, 20);
currentPg.addSetStandardFieldTextValue(“templateElementName”, “text value”);
currentPg.addSetStandardFieldUserDefinedValue(“templateElementName”, “value”);

// 3. step – build a combined update RQL command and trigger it

The first step simply empty the internally used list to remember the page element values and prepare so for step 2. You can use any method used in step 2 as often as you want – as long as they are on the same page.  Step 3 itself calls the CMS with only one RQL command and therefore boosts performance.

Neiter are text elements nor image or media element supported for a combined update. But you can trigger updates on these kind of elements at any time beside you are collecting new element values.
