org.datanucleus.store.connection.ConnectionManagerImpl

Manager of connections for a datastore, allowing ManagedConnection pooling, enlistment in transaction. The pool caches one connection per poolKey object. The "allocateConnection" method can create connections and enlist them (like most normal persistence operations need) or create a connection and return it without enlisting it into a transaction, for example the connections used to generate object identity, create the database schema or obtaining the schema metadata. Connections can be locked per object poolKey basis. Locking of connections is used to handle the connection over to the user application. A locked connection denies any further access to the datastore, until the user application unlock it.
