Examples of org.apache.stanbol.commons.solr.SolrServerAdapter

org.apache.stanbol.commons.solr.SolrServerAdapter
This Class 'wraps' a Solr {@link CoreContainer} with all its registered {@link SolrCore}s and registers them as OSGI services. It therefore adapts the components framework as used by Apache Solr to the OSGI.
This class itself is no OSGI component, but is intended to be used by other classes that allow to register/manage Solr {@link CoreContainer}running within the same JVM.
Properties set for CoreContainers are:
- {@link SolrConstants#PROPERTY_SERVER_NAME}: The name assigned to the SolrServer as parsed by {@link SolrServerProperties#getServerName()}. If not defined than the directory of the SolrServer is used as name
- {@link SolrConstants#PROPERTY_SERVER_DIR} the directory of the {@link CoreContainer} (SolrHome)
- {@link SolrConstants#PROPERTY_SOLR_XML_NAME}: the name of the 'solr.xml' file
- {@link SolrConstants#PROPERTY_SERVER_RANKING}: The {@link Constants#SERVICE_RANKING} for the {@link CoreContainer} used for allits core if not overridden.
Properties set for {@link SolrCore}s are:
- The {@link SolrConstants#PROPERTY_SERVER_NAME name} and {@link SolrConstants#PROPERTY_SERVER_DIR dir} of the {@link CoreContainer} this {@link SolrCore} is part of
- {@link SolrConstants#PROPERTY_CORE_NAME}: The name this SolrCore is registered with the CoreContainer.
- {@link SolrConstants#PROPERTY_CORE_DIR}: The {@link CoreDescriptor#getInstanceDir() instance directory} of this SolrCore.By default this is ' {@link SolrConstants#PROPERTY_SERVER_DIR CoreContainer.dir}/ {@link SolrConstants#PROPERTY_CORE_NAME SolrCore.name}'
- The {@link SolrConstants#PROPERTY_CORE_SCHEMA} and {@link SolrConstants#PROPERTY_CORE_SOLR_CONF} holding the names of theaccording core configuration files.
- The {@link SolrConstants#PROPERTY_CORE_DATA_DIR} and{@link SolrConstants#PROPERTY_CORE_INDEX_DIR}.
- The {@link SolrConstants#PROPERTY_CORE_RANKING}: the {@link Constants#SERVICE_RANKING} for the {@link SolrCore}. If not set the service ranking of the {@link CoreContainer} is used.
Notes:
- {@link CoreContainer} does not provide Events for changes in its configuration.Therefore the OSGI service registration for the CoreContainer can only be assured if the interface of this Class is used to change the state of the CoreContainer.
- {@link SolrCore}s allow to register a {@link CloseHook} to get notified if aSolrCore is closed. Therefore this implementation can assure that closed {@link SolrCore}s are also unregistered as OSGI services.
