  • Method Details

    • store

      public void store(String indexName, IndexArchive archive) throws IOException
      Specified by:
      store in interface IndexArchiveProvider
      Throws:
      IOException

    • hasData

      public boolean hasData(String indexName)
      Description copied from interface: AbstractDataProvider

      Respond with 'true' if this provider is generally able to provide data for the requested index. This is a quick check when initializing the suggesters, so it should not take too long.

      It's also possible to return a static "true" here and do the expensive availability check at the getLastDataModTime method, which is called async. If getLastDataModTime returns a value < 0, data update are canceled as well.

      Specified by:
      hasData in interface AbstractDataProvider<IndexArchive>
      Parameters:
      indexName - identifier for the requested data
      Returns:
      if data is available

    • getLastDataModTime

      public long getLastDataModTime(String indexName) throws IOException
      Description copied from interface: AbstractDataProvider

      Get the timestamp from when the data was modified the last time. For every change of that timestamp, the data will be pulled and indexed into suggest index.

      Setting the timestamp at the data is optional, but if it is set there, it MUST be the same timestamp, otherwise the data is rejected. This feature is used to avoid potential concurrency issues.

      If data is not available at all, a value < 0 should be returned.

      Specified by:
      getLastDataModTime in interface AbstractDataProvider<IndexArchive>
      Parameters:
      indexName - identifier for the requested data
      Returns:
      unix timestamp in millis
      Throws:
      IOException - if resource is not available

    • loadData

      public IndexArchive loadData(String indexName) throws IOException
      Specified by:
      loadData in interface AbstractDataProvider<IndexArchive>
      Parameters:
      indexName - identifier for the requested data
      Returns:
      suggest data
      Throws:
      IOException - if data couldn't be loaded
