Where is the state root being updated in Aleth CPP?

Question

Can someone point me to where the state root is updated after each transaction is executed in the block? This is for Aleth

Answer 1

I found it myself:

template <class DB> void GenericTrieDB<DB>::insert(bytesConstRef _key, 
bytesConstRef _value)
{
std::string rootValue = node(m_root);
assert(rootValue.size());
bytes b = mergeAt(RLP(rootValue), m_root, NibbleSlice(_key), _value);

// mergeAt won't attempt to delete the node if it's less than 32 bytes
// However, we know it's the root node and thus always hashed.
// So, if it's less than 32 (and thus should have been deleted but wasn't) 
then we delete it here.
if (rootValue.size() < 32)
    forceKillNode(m_root);
m_root = forceInsertNode(&b);
}
