      public EOLProfilerDataSource(DataSourceDescriptor descriptor, String source, Hashtable properties) throws VisADException
      Create a new EOLProfilerDataSource
      Parameters:
      descriptor - description of source

  • Method Details

    • initAfterUnpersistence

      public void initAfterUnpersistence()
      Extends method in DataSourceImpl to call local initProfiler ()
      Specified by:
      initAfterUnpersistence in interface DataSource
      Overrides:
      initAfterUnpersistence in class DataSourceImpl

    • newFileFromPolling

      public void newFileFromPolling(File f)
      If we are polling some directory this method gets called when there is a new file. We set the file name, clear our state, reload the metadata and tell listeners of the change.
      Overrides:
      newFileFromPolling in class DataSourceImpl
      Parameters:
      f - new File to use.

    • getLocationsForPolling

      protected List getLocationsForPolling()
      Get the location where we poll.
      Overrides:
      getLocationsForPolling in class DataSourceImpl
      Returns:
      File to poll on.

    • doMakeDataChoices

      public void doMakeDataChoices()
      Called by DataSourceImpl to make the actual DataChoice(s) and add them to a list of Datachoices; the DataSourceImpl then checks to see if any derived datachoices are possible to derive from these, and shows them if so. Used data supplied in the constructor.
      Overrides:
      doMakeDataChoices in class DataSourceImpl

    • getDataInner

      protected Data getDataInner(DataChoice dataChoice, DataCategory category, DataSelection dataSelection, Hashtable requestProperties) throws VisADException, RemoteException
      Actually get the data identified by the given DataChoce. The default is to call the getDataInner that does not take the requestProperties. This allows other, non unidata.data DataSource-s (that follow the old API) to work.
      Overrides:
      getDataInner in class DataSourceImpl
      Parameters:
      dataChoice - The data choice that identifies the requested data.
      category - The data category of the request.
      dataSelection - Identifies any subsetting of the data.
      requestProperties - Hashtable that holds any detailed request properties.
      Returns:
      The visad.Data object
      Throws:
      RemoteException - Java RMI problem
      VisADException - VisAD problem
