## Package org.firebirdsql.gds.ng Description

Provides the abstraction for connecting to Firebird either through a wire protocol implementation, a native firebird client or other means. These classes are used by the JDBC implementation of Jaybird.

The classes in this package (and its subpackages) can be used directly but the stability of the interface is not guaranteed (not even between point releases) for the next few versions. We strongly advise to use the JDBC implementation.

The classes and interfaces provided by this package can be used to add additional protocol implementations, but given the expected volatility of the interface (see above) we urge you to use caution.

Since:
  3.0
