Class TelemetryModel

java.lang.Object

javax.swing.table.AbstractTableModel

org.ka2ddo.yaac.gui.TelemetryModel

All Implemented Interfaces:

java.io.Serializable, javax.swing.table.TableModel, TrackerListener

public class TelemetryModel
extends javax.swing.table.AbstractTableModel
implements TrackerListener

This class extracts the background data for reporting current telemetry data from telemetering stations. Each report consists of 2 rows with 14 columns. The first row contains the station-specific column titles (from the PARMS message). The second row contains the station callsign, the 5 scaled analog values, and the 8 boolean bits.

Method Detail

getTelemetryStationCount

public int getTelemetryStationCount()

Get the number of monitored stations currently sending telemetry data.

Returns:

station count

getColumnName

public java.lang.String getColumnName(int column)

Returns the localized name for the column.

Specified by:

getColumnName in interface javax.swing.table.TableModel

Overrides:

getColumnName in class javax.swing.table.AbstractTableModel

Parameters:

column - the column being queried

Returns:

a string containing the name of column

getColumnCount

public int getColumnCount()

Returns the number of columns in the model.

Specified by:

getColumnCount in interface javax.swing.table.TableModel

Returns:

the number of columns in the model

See Also:

getRowCount()

getRowCount

public int getRowCount()

Returns the number of rows in the model. A JTable uses this method to determine how many rows it should display. This method should be quick, as it is called frequently during rendering.

Specified by:

getRowCount in interface javax.swing.table.TableModel

Returns:

the number of rows in the model

getColumnCount()

getValueAt

public java.lang.Object getValueAt(int rowIndex,
                                   int columnIndex)

Returns the value for the cell at columnIndex and rowIndex.

Specified by:

getValueAt in interface javax.swing.table.TableModel

Parameters:

rowIndex - the row whose value is to be queried

columnIndex - the column whose value is to be queried

Returns:

the value Object at the specified cell

messageAdded

public void messageAdded(StationState ss,
                         int index,
                         AX25Message msg)

Called when a Message is added to the history for a station in the tracker.

Specified by:

messageAdded in interface TrackerListener

Parameters:

ss - StationState containing the station's information

index - zero-based index of the message added to the StationState object

msg - APRS Message object being added to the tracker; note that non-APRS packets

messageDeleted

public void messageDeleted(StationState ss,
                           int index,
                           AX25Message msg)

Called when a AX25Message is deleted from the history for a station in the tracker.

Specified by:

messageDeleted in interface TrackerListener

Parameters:

ss - StationState containing the station's information; the AX25Message will already be removed from the StationState object

index - zero-based index of the message removed from the StationState object

msg - APRS Message object being removed from the tracker; note that non-APRS packets that can still be decoded (such as OpenTRAC) will also be passed here; AX25Frames that cannot be decoded will pass null here

stationAdded

public void stationAdded(StationState ss,
                         int index)

Called when a new station is initially added to the tracker.

Specified by:

stationAdded in interface TrackerListener

Parameters:

ss - StationState containing the station's information; the initial AX25Message will not yet be stored within the StationState object

index - zero-based integer sequence number for this station in the StationTracker

stationUpdated

public void stationUpdated(StationState ss)

Called when an existing station is updated with new information in the tracker.

Specified by:

stationUpdated in interface TrackerListener

Parameters:

ss - StationState containing the station's information; the new AX25Message will not yet be stored within the StationState object

stationDeleted

public void stationDeleted(StationState ss,
                           int index)

Called when an existing station is deleted from the tracker.

Specified by:

stationDeleted in interface TrackerListener

Parameters:

ss - StationState containing the station's information

index - zero-based integer sequence number for this station in the StationTracker

removeTableModelListener

public void removeTableModelListener(javax.swing.event.TableModelListener l)

Removes a listener from the list that's notified each time a change to the data model occurs.

Specified by:

removeTableModelListener in interface javax.swing.table.TableModel

Overrides:

removeTableModelListener in class javax.swing.table.AbstractTableModel

Parameters:

l - the TableModelListener
