function ClassDiscovery::safeClassExists

We need a "safe" version of PHP's "class_exists" because Magento has a bug (or they call it a "feature"). Magento is throwing an exception if you do class_exists() on a class that ends with "Factory" and if that file does not exits.

This function catches all potential exceptions and makes sure to always return a boolean.

Parameters

string $class:

Return value

bool
