Package net.dpml.transit.model Description

The model package contains a set of interfaces that define an active configuration model. The TransitModel class defines the rot of the configuration model from which CacheModel, RegistryModel and RepositoryModel instances are accessible. The CacheModel provides information about the configured cache directory and hosts. Hosts are exposed as instances of HostModel. The RegistryModel provides information about registered content handler plugins via instances of ContentModel. The RepositoryModel declares information about the repository service (plugin loading and general classloader chain construction).
