Detailed Description

PostgreSQL Lease Context.

This class stores the thread context for the manager pool. The class is needed by all get/update/delete functions which must use one or more exchanges to perform database operations. Each context provides a set of such exchanges for each thread. The context instances are lazy initialized by the requesting thread by using the manager's createContext function and are destroyed when the manager's pool instance is destroyed.
