Exactly how would I use the hooks hookActionPresentProduct and hookActionPresentProductListing?

[zunxunz]

Both those hooks seem very useful to manipulate product data before displaying the products, but the 'product' and 'presentedProduct' elements of $params are private and protected respectively. There don't seem to be any setters available either to change or add values, so how would I use those hooks to manipulate the data?

There are methods to use, look for offsetSet method of the presented product.

Can you be a little more specific?

For instance, I'm looking to set 'show_price' to false for some specific products under certain conditions.

 

But
$params['presentedProduct']->offsetSet('show_price' false);

or 

$params['presentedProduct']['show_price'] = false;

will both raise an exception, since 'show_price' is 'blocked' by a getter on the ProductLazyArray.

For that you should check Filter hooks.
filterCategoryContent
filterProductContent
filterProductSearch
Usually there hooks are called right before displaying. 

For offsetSet check AbstractLazyArray.

Cytat

    public function offsetSet($offset, $value, $force = false): void

    {

        if (!$force && $this->arrayAccessList->offsetExists($offset)) {

            $result = $this->arrayAccessList->offsetGet($offset);

            if ($result['type'] !== 'variable') {

                throw new RuntimeException('Trying to set the index ' . print_r($offset, true) . ' of the LazyArray ' . get_class($this) . ' already defined by a method is not allowed');

            }

        }

        $this->arrayAccessList->offsetSet($offset, [

            'type' => 'variable',

            'value' => $value,

        ]);

    }

offsetSet works fine, you just need to use the $force paramater

You receive a ProductLazyArray in $params['presentedProduct']

To change a value you use offsetSet() because the properties are protected
 

public function hookActionPresentProductListing($params)
{
    $product = $params['presentedProduct'];
    $product->offsetSet('show_price', false);
}

This allows you to change or inject values before the product is rendered on the front end
