Constructor Detail

FolderInputSystem

public FolderInputSystem()

Method Detail

runFileAnalysis

public boolean runFileAnalysis()

Overrides:

runFileAnalysis in class FileInputSystem

prepareInputFile

public boolean prepareInputFile()

Description copied from class: FileInputSystem

Open the audio stream for processing.

Overrides:

prepareInputFile in class FileInputSystem

Returns:

true if audio stream opeend correctly.

getFolderFileFilter

public PamFileFilter getFolderFileFilter()

interpretNewFile

public void interpretNewFile(java.lang.String newFile)

Overrides:

interpretNewFile in class FileInputSystem

setFileDateText

public void setFileDateText()

getSystemType

public java.lang.String getSystemType()

Overrides:

getSystemType in class FileInputSystem

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 FileInputSystem

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 FileInputSystem

Returns:

A Name specific to the type, e.g. Glick detector

getCurrentFile

public java.io.File getCurrentFile()

Overrides:

getCurrentFile in class FileInputSystem

daqHasEnded

public void daqHasEnded()

Description copied from class: DaqSystem

Called after DAQ has stopped - for whatever reason. Nost DAQ systems will not need to do anything here, but they could potentially clean up memory The motivation for putting this here now is for the folder analysis system so that it can start analysing the next file.

Overrides:

daqHasEnded in class FileInputSystem

getStatusBarComponent

public java.awt.Component getStatusBarComponent()

Overrides:

getStatusBarComponent in class FileInputSystem

getEta

public long getEta()

Overrides:

getEta in class FileInputSystem

getSettingsReference

public java.io.Serializable getSettingsReference()

Specified by:

getSettingsReference in interface PamSettings

Overrides:

getSettingsReference in class FileInputSystem

Returns:

The serialisable object that will be stored

getSettingsVersion

public long getSettingsVersion()

Specified by:

getSettingsVersion in interface PamSettings

Overrides:

getSettingsVersion in class FileInputSystem

Returns:

An integer version number for the settings

dialogGetParams

public boolean dialogGetParams()

Description copied from class: DaqSystem

Called by AcquisitionDialog.GetParams so that parameters can be extracted from the dialog component. The DaqSystem should also implement PamSettings and handle storage of parameters between runs.

Overrides:

dialogGetParams in class FileInputSystem

Returns:

true if the parameters and selections are OK. If false is returned the Acquisition dialog will not respond to its Ok button.

dialogSetParams

public void dialogSetParams()

Description copied from class: DaqSystem

Called by AcquisitionDialog.SetParams so that the dialog componenet can update it's fields

Overrides:

dialogSetParams in class FileInputSystem

restoreSettings

public boolean restoreSettings(PamControlledUnitSettings pamControlledUnitSettings)

Specified by:

restoreSettings in interface PamSettings

Overrides:

restoreSettings in class FileInputSystem

Returns:

true if successful The object performs final checks (if needed) and then casts the settings data pamcontrolledunitSettings.settings into the correct type and uses as required

getFolderInputParameters

public FolderInputParameters getFolderInputParameters()

setFolderInputParameters

public void setFolderInputParameters(FolderInputParameters folderInputParameters)

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 FileInputSystem

Parameters:

daqControl - AcquisitionControl unit.

Returns:

true if OK, false otherwise

getDeviceName

public java.lang.String getDeviceName()

Description copied from class: DaqSystem

Gets a name for the acquisition device (may just be a number but need to generalise).

Overrides:

getDeviceName in class FileInputSystem

Returns:

getAudioFileFilter

public PamFileFilter getAudioFileFilter()

setAudioFileFilter

public void setAudioFileFilter(PamFileFilter audioFileFilter)
