    • setupProcess

      public void setupProcess()
      Description copied from class: PamProcess

    • getFrequencyRange

      public double[] getFrequencyRange()
      Description copied from class: PamProcess
      Get the range of frequencies over which the data in this process are likely to be present.

      public DelayMeasurementParams getDelayMeasurementParams(ClickDetection pamDetection)
      Get appropriate delay measurement parameters depending on the click type. 31/11/2016 MO: originally this method was passed a PamDetection which was immediately cast to a Click Detection. All classes calling this method passed a ClickDetection anyway, and since we've now removed the PamDetection class I've just changed the parameter to ClickDetection and commented out the cast.
      Parameters:
      pamDetection -
      Returns:
      appropriate click delay measurement parameters.

    • completeClick

      Once a click is detected, does everything else to it such as calculate bearing, check species, send to click train detector, etc.
      Returns:
      true if the tasks complete successfully and the click is to be kept. false otherwise.

    • measureDelays

      public double[] measureDelays(ClickDetection click)
      Measure time delays between raw waveforms within a single click detection (multiple channels within) a single group.
      Parameters:
      click - - the click detection
      Returns:
      a list of time delays between all channels in seconds.

      flushDataBlockBuffers in class PamProcess
      Parameters:
