A generic DAO interface for a pojo and a primary key type.

This type is implemented by generated DAO classes to provide a common API for common actions on POJOs

Author:Lukas Eder
Type parameters:
  • <R> – The generic record type.
  • <P> – The generic POJO type.
  • <T> – The generic primary key type. This is a regular <T> type for single-column keys, or a Record subtype for composite keys.
