Class PostgresIdentity

java.lang.Object

io.github.blyznytsiaorg.bibernate.dao.jdbc.identity.PostgresIdentity

All Implemented Interfaces:

Identity

public class PostgresIdentity
extends Object
implements Identity

Implementation of the Identity interface for managing identity-related operations in Bibernate application specific to PostgreSQL databases. It delegates entity-saving operations to different generators based on the GenerationType strategy specified in the entities' annotations. Supports NONE, SEQUENCE, and IDENTITY GenerationType strategies.
