This helper class provides shorter alternative for saving and restoring active block in renderer.
Instead of using code like below
Block *old_block_ptr{ renderer->ActiveBlock }, old_block;
if (old_block_ptr)
{
old_block = *old_block_ptr;
old_block_ptr = &old_block;
}
...
// Change active block in renderer
...
renderer->ActivateBlock(old_block_ptr);you may shorten it to the following one.
CStoreBlock store{ renderer };
...
// Change active block in renderer
...class CStoreBlock final
{
public:
CStoreBlock(IRenderer *renderer);
~CStoreBlock();
