Constructor Detail

RonaInputSystem

public RonaInputSystem(AcquisitionControl acquisitionControl)

Method Detail

getSystemType

public java.lang.String getSystemType()

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 java.lang.String getUnitName()

Specified by:

getUnitName in interface PamSettings

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 java.lang.String getUnitType()

Specified by:

getUnitType in interface PamSettings

Overrides:

getUnitType in class FolderInputSystem

Returns:

A Name specific to the type, e.g. Glick 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 opeend correctly.

getChannelFile

public java.io.File getChannelFile(java.io.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 java.io.File findChannelFile(java.io.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:

stopSystem in class FileInputSystem
