Examples of org.fcrepo.server.DatastoreConfig

org.fcrepo.server.DatastoreConfig
A holder of configuration name-value pairs for a datastore.
A datastore is a system for retrieving and storing information. This class is a convenient placeholder for the configuration values of such a system.
Configuration values for datastores are set in the server configuration file. (see fedora-config.xsd) @author Chris Wilper
