IUnitOfWorkFactory

IUnitOfWorkFactory is the seam contract consuming applications depend on to obtain a NHibernateUnitOfWork for a connection string, without needing to know which database engine or session strategy (stateful/stateless) the concrete factory (OracleUnitOfWorkFactory, OracleStatelessUnitOfWorkFactory, SqlServerUnitOfWorkFactory) uses.

Purpose

• Defines the single operation (GetUnitOfWork) consumers call to obtain a transaction-scoped unit of work bound to a freshly opened NHibernate session.
• Allows application code to depend on this interface for dependency injection rather than a concrete engine-specific factory class.

Context

• Namespace: SAIF.Data.NHibernate
• Assembly/package: SAIF.Framework.Data.NHibernate

Public members

Member	Signature	Purpose
GetUnitOfWork	NHibernateUnitOfWork GetUnitOfWork(string connectionString, int batchSize, bool showSql)	Resolves (or builds and caches) an ISessionFactory for connectionString, opens a session appropriate to the implementation's engine/session-strategy combination, and returns a NHibernateUnitOfWork wrapping it.

Behavioral notes

• Every call returns a new NHibernateUnitOfWork bound to a freshly opened session — the ISessionFactory is cached and reused, but the session/unit-of-work is not (see BR-005).

Constraints and usage notes

• Implementers must be constructed with a matching IConfigurationFactory so the session factory targets the correct database engine.
