Examples of org.exist.storage.BrokerPool

org.exist.storage.BrokerPool
This class controls all available instances of the database. Use it to configure, start and stop database instances. You may have multiple instances defined, each using its own configuration. To define multiple instances, pass an identification string to {@link #configure(String,int,int,Configuration)}and use {@link #getInstance(String)} to retrieve an instance. @author Wolfgang Meier @author Pierrick Brihaye
