Detailed Description

Base class for things that monopolise a transaction's attention.

You probably won't need to use this class. But it can be useful to know that a given libpqxx class is derived from it.

Pipelines, SQL statements, and data streams are examples of classes derived from transaction_focus. In any given transaction, only one object of such a class can be active at any given time.
