The following transformations can be applied to any class to simplify greatly the development of Multi-Tenant applications. These include:

- `@CurrentTenant` - Resolve the current tenant for the context of a class or method
- `@Tenant` - Use a specific tenant for the context of a class or method
- `@WithoutTenant` - Execute logic without a specific tenant (using the default connection)

For example:

[source,groovy]
----
import grails.gorm.multitenancy.*

// resolve the current tenant for every method
@CurrentTenant
class TeamService {

    // execute the countPlayers method without a tenant id
    @WithoutTenant
    int countPlayers() {
        Player.count()
    }

    // use the tenant id "another" for all GORM logic within the method
    @Tenant({"another"})
    List<Team> allTwoTeams() {
        Team.list()
    }

    List<Team> listTeams() {
        Team.list(max:10)
    }

    @Transactional
    void addTeam(String name) {
        new Team(name:name).save(flush:true)
    }
}
