See src/graphics/Previews.C
This iterates over all top level insets.

void Previews::generateBufferPreviews(Buffer const & buffer) const
{
    PreviewLoader & ploader = loader(buffer);

    InsetBase & inset = buffer.inset();
    InsetIterator it = inset_iterator_begin(inset);
    InsetIterator const end = inset_iterator_end(inset);

    for (; it != end; ++it)
        it->addPreview(ploader);

    ploader.startLoading();
}

And this, in src/graphics/PreviewLoader.C iterates over all top level math 
macro insets.

    // Loop over the insets in the buffer and dump all the math-macros.
    InsetBase & inset = buffer_.inset();
    InsetIterator it = inset_iterator_begin(inset);
    InsetIterator const end = inset_iterator_end(inset);

    for (; it != end; ++it)
        if (it->lyxCode() == InsetBase::MATHMACRO_CODE)
            it->latex(buffer_, os, runparams);

Is hat enough info?

I think that that was a goal, yes.
