-/**
- * Interceptor that keep track of connection state to avoid roundtrips to the database.
- * The {@link org.apache.tomcat.jdbc.pool.ConnectionPool} is optimized to do as little work as possible.
- * The pool itself doesn't remember settings like {@link java.sql.Connection#setAutoCommit(boolean)},
- * {@link java.sql.Connection#setReadOnly(boolean)}, {@link java.sql.Connection#setCatalog(String)} or
- * {@link java.sql.Connection#setTransactionIsolation(int)}. It relies on the application to remember how and when
- * these settings have been applied.
- * In the cases where the application code doesn't know or want to keep track of the state, this interceptor helps cache the
- * state, and it also avoids roundtrips to the database asking for it.
