Instance Method Details

#connect(&bl) ⇒ Object

Connects to the database, starts a transaction if required, then yields the block with the connection object.

The connection is kept under an instance variable and can be later obtained through the connection accessor. Do NOT use this method without having called dup on the config object as it relies on shared mutable state.
