Class ManagedSynonymGraphFilterFactory

  • All Implemented Interfaces:
    org.apache.lucene.analysis.util.ResourceLoaderAware, ManagedResourceObserver

extends BaseManagedTokenFilterFactory
    TokenFilterFactory and ManagedResource implementation for doing CRUD on synonyms using the REST API.
    Since:

    SPI Name (Note: This is case-insensitive. e.g., if the name is 'htmlStrip', 'htmlstrip' can be used when looking up the service):

    • Nested Class Summary

      Nested Classes 
      Modifier and Type Class Description
      static class  ManagedSynonymGraphFilterFactory.SynonymManager
      ManagedResource implementation for synonyms, which are so specialized that it makes sense to implement this class as an inner class as it has little application outside the SynonymFilterFactory use cases.

      protected Class<? extends ManagedResource> getManagedResourceImplClass()
      Let the concrete analysis component determine the ManagedResource implementation.

      Let the concrete analysis component decide the path it wishes to be managed at.
      void onManagedResourceInitialized​(NamedList<?> initArgs, ManagedResource res)
      Called once, during core initialization, to initialize any analysis components that depend on the data managed by this resource.

      • getManagedResourceImplClass

        protected Class<? extends ManagedResource> getManagedResourceImplClass()
        Description copied from class: BaseManagedTokenFilterFactory
        Let the concrete analysis component determine the ManagedResource implementation. As there can be many instances of the same analysis component in a schema, this class should not presume to create ManagedResource. For instance, there may be 10 instances of the ManagedStopFilterFactory that use the same set of English stop words and we don't want 10 copies of the ManagedWordSetResource in the same core.

      • onManagedResourceInitialized

        public void onManagedResourceInitialized​(NamedList<?> initArgs,
                                         ManagedResource res)
                                  throws SolrException
        Called once, during core initialization, to initialize any analysis components that depend on the data managed by this resource. It is important that the analysis component is only initialized once during core initialization so that text analysis is consistent, especially in a distributed environment, as we don't want one server applying a different set of stop words than other servers.
        Throws:
        SolrException
