Answer 1

Overall, using the terms in the variable names, it stores the return-value of the currentHtml() function into the manifest‘s currentItem‘s fileContent variable.

To break it down:

((ManifestItem*)manifest->currentItem())

There is a method, currentItem() in your manifest class that will return the, well, “current item”. The (ManifestItem*) will cast this returned item to a ManifestItem data type.

The rest is, I hope, self-explanatory:

->fileContent = currentHtml();
