Class MultiTenancyImplementation

java.lang.Object

org.hibernate.engine.jdbc.connections.spi.AbstractMultiTenantConnectionProvider

com.manydesigns.portofino.persistence.hibernate.multitenancy.MultiTenancyImplementation

All Implemented Interfaces:

Serializable, MultiTenantConnectionProvider, Service, Configurable, ServiceRegistryAwareService, Stoppable, Wrapped

Direct Known Subclasses:

SchemaBasedMultiTenancy

public abstract class MultiTenancyImplementation
extends AbstractMultiTenantConnectionProvider
implements ServiceRegistryAwareService, Configurable, Stoppable

This class has two purposes:

1. act as an AbstractMultiTenantConnectionProvider for Hibernate, selecting a different connection provider for each tenant;
2. act as a strategy for Portofino to compute the current tenant.

Given that the two purposes have overlapping needs, and we can't use inner classes (because this will be instantiated reflectively both by Portofino and by Hibernate), we've settled on a single class even if it's not properly designed OO. Implementors should keep in mind that two instances will be created to perform the two different tasks, and they will not share state.
