What is the equivalent to getLastInsertId() in Cakephp?

CakePHP has two methods for getting the last inserted id: Model::getLastInsertID() and Model::getInsertID().
Actually these methods are identical so it really doesn’t matter which method you use.

echo $this->ModelName->getInsertID();
echo $this->ModelName->getLastInsertID();

This methods can be found in cake/libs/model/model.php on line 2768
