scans for factory plug-ins on the application class path . this method is needed because the application class path can theoretically change , or additional plug-ins may become available . rather than re-scanning the classpath on every invocation of the api , the class path is scanned automatically only on the first invocation . clients can call this method to prompt a re-scan . thus this method need only be invoked by sophisticated applications which dynamically make new plug-ins available at runtime . concode_field_sep Set<OIndexFactory> FACTORIES concode_elem_sep ClassLoader orientClassLoader concode_elem_sep Set<OIndexFactory> DYNAMIC_FACTORIES concode_field_sep void registerFactory concode_elem_sep Set<OIndexFactory> getFactories concode_elem_sep Iterator<OIndexFactory> getAllFactories concode_elem_sep Set<String> getIndexEngines concode_elem_sep void unregisterFactory concode_elem_sep OIndexFactory getFactory concode_elem_sep Set<String> getIndexTypes concode_elem_sep OIndexInternal<?> createIndex
