close

public void close()

Description copied from class: SSessionJdbc

Main method for closing a session.

Closes the JDBC connection and then calls detachWithoutClosing to detach the SimpleORM connection from the current thread. Should usually be put in a finally clause. No error if already detached or closed so safe in finally clauses.

Specified by:

close in interface AutoCloseable

Overrides:

close in class SSessionJdbc
