Examples of org.apache.tapestry.services.Alias

org.apache.tapestry.services.Alias
Primarily, the Alias service is an ObjectProvider that fits into the command chain and disambiguates injections on type. Contributions to the Alias service identify the normal service to inject for a particular service interface; this is only necessary when there is more than one service implementing the same interface.
