Again, this constructor takes two different forms of input data and creates one application
interface. Note that while some of the handling code could be made more generic,
some tricky attributes such as reviews have different names depending on the method.
Having gone through all this processing to retrieve the data, you now return control
back to the getARS() function and hence back to showBrowseNode().The next step is
showSummary($ars->products(), $page,
$ars->totalResults(), $mode,
$browseNode);
The showSummary() function simply displays the data in the AmazonResultSet, as you
can see it all the way back in Figure 33.1.We therefore did not include the function
here.
