symfony1 - How to identify ORM - Propel calls in many lines of Symony code? -

i new propel. , have project using propel. , need identify propel calls in many lines of code. project made in symfony.

by specifications can find propel calls ?

i mean evrey propel::getconnection() connections can used in multiple propel calls ?

or shall need every new criteria(); , [theobiect]peer:: ?

the connections (in experience @ least) totally handled behind scenes. created automatically if needed , re-used if available. searching propel::getconnection() not help. you'll need @ least search listed above. raw model objects have references peers, in modelobject->save(). goal?
