Sample code for exception handling

Sample scripting based import

Sample code for exception handling in a scripting based import script:

var parser = newCSVParser(in);
var bDone = false;
while(!bDone)
{
    var attrs = parser.splitLine();
    bDone = (null == attrs);
    if (!bDone)
    {
        catchError(e, errObj)
        {
            // The user-written function getNewItemUsingAttrs() 
            // populates an item object from the attrs
            var item = getNewItemUsingAttrs(attrs);
            item.saveCtgItem();
        }
        if (errObj != null)
        {
            // The user-written function isCriticalError() uses Java to interrogate errObj
            if (isCriticalError(e, errObj))
            {
                throwError("Critical error occurred in import job: " + e);
            }
        }
    }
}

Sample scripting based report

Sample code for exception handling in a scripting based report script. This applies to a report script written to import items:

var bDone = false;
var numItemsInTxn = 0;
var numItemsPerTxn = 200;
while(!bDone)
{
    catchError(e, errObj)
    {
        useTransaction
        {
            numItemsInTxn=0;
            while (!bDone && numItemsInTxn < numItemsPerTxn)
            {
                // The user-written function getNextItemToSave()
                // returns the next item object to persist
                var item = getNextItemToSave();
                bDone = (null == item);
                if (!bDone)
                {
                    item.saveCtgItem();
                    numItemsInTxn++;
                }
            }
        }
    }
    if (errObj != null)
    {
        // The user-written function isCriticalError() uses Java to interrogate errObj
        if (isCriticalError(e, errObj))
        {
            throwError("Critical error occurred in import job: " + e);
        }
    }
}
