      Overrides:
      getSystemType in class FolderInputSystem
      Returns:
      The 'type' of data source for display in the Data Source dialog

      Calling functions should be able to handle 'null'

    • getUnitName

      public String getUnitName()
      Specified by:
      getUnitName in interface SettingsNameProvider
      Overrides:
      getUnitName in class FolderInputSystem
      Returns:
      A Name specific to this instance of the particular class, e.g. Sperm whale detector, Beaked whale detector, etc.

    • getUnitType

      public String getUnitType()
      Specified by:
      getUnitType in interface PamSettings
      Overrides:
      getUnitType in class FolderInputSystem
      Returns:
      A Name specific to the type, e.g. Click detector

    • getFolderFileFilter

      public PamFileFilter getFolderFileFilter()
      Overrides:
      getFolderFileFilter in class FolderInputSystem

    • getMaxChannels

      public int getMaxChannels()
      Overrides:
      getMaxChannels in class FileInputSystem
      Returns:
      the maximum number of channels supporrted by the selected device, or PARAMETER_UNKNOWN

    • getChannels

      public int getChannels()
      Overrides:
      getChannels in class FileInputSystem

    • getInputChannelMap

      public int getInputChannelMap(AcquisitionParameters acquisitionParameters)
      Overrides:
      getInputChannelMap in class DaqSystem
      Returns:
      a bitmap of output channels. this should ALWAYS be a bitmap of channels 0 to n-1 even if different hardware channels are used since hardware channels are no longer passed through PAMGUARD.

    • prepareInputFile

      public boolean prepareInputFile()
      Description copied from class: FileInputSystem
      Open the audio stream for processing.
      Overrides:
      prepareInputFile in class FolderInputSystem
      Returns:
      true if audio stream opened correctly.

    • getChannelFile

      public File getChannelFile(File baseFile, int index)
      swap the last digit in a file name for the higher channel number - rememebr the channels are one indexed.
      Parameters:
      baseFile - base file
      index - 0 based file index
      Returns:
      new file with the 1 replaced by another number

    • findChannelFile

      public File findChannelFile(File baseFile, int index, int searchRange)
      Search for a nearby file with the same name, but secondds may differ by one or two secs - may need to generate complete new file names !
      Parameters:
      baseFile -
      index -
      searchRange -
      Returns:

    • prepareSystem

      public boolean prepareSystem(AcquisitionControl daqControl)
      Description copied from class: DaqSystem
      Prepare the DaqSystem.

      Usually this is the time for opening files, preparing data buffers, etc.

      Overrides:
      prepareSystem in class FileInputSystem
      Parameters:
      daqControl - AcquisitionControl unit.
      Returns:
      true if OK, false otherwise.

    • startSystem

      public boolean startSystem(AcquisitionControl daqControl)
      Description copied from class: DaqSystem
      Start the DaqSystem. This is called immediately after PrepareSystem

      Most things should be ready from the call to PrepareSystem. In StartSystem you will generally need to start a thread which will read in the data and place PamDataUnits in a buffer from where they are read by the main thred and passed on to other Pam modules for processing (see SoundCardSystem for an example)

      Overrides:
      startSystem in class FolderInputSystem
      Parameters:
      daqControl - AcquisitionControl unit.
      Returns:
      true if OK, false otherwise

    • setChannelRunning

      public void setChannelRunning(int channel, boolean running)

    • stopSystem

      public void stopSystem(AcquisitionControl daqControl)
      Description copied from class: DaqSystem
      Stop the DaqSystem.
      Overrides:
