the instance of DXTableModel.

aprsMessageReceived

public void aprsMessageReceived(Message msg)

Delivers the next message received by YAAC that is an APRS message.

Specified by:

aprsMessageReceived in interface AprsMessageListener

Parameters:

msg - some subclass of Message containing the message contents; the message should have an AX25Frame connected to it

Specified by:

getRowCount in interface javax.swing.table.TableModel

Returns:

the number of rows in the model

See Also:

getColumnCount()

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

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

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

getColumnClass

public java.lang.Class<?> getColumnClass(int columnIndex)

Returns the class of data in the column.

Specified by:

getColumnClass in interface javax.swing.table.TableModel

Overrides:

getColumnClass in class javax.swing.table.AbstractTableModel

Parameters:

columnIndex - the column being queried

Returns:

the Object.class

getColumnWidth

public int getColumnWidth(int columnIndex)

Specifies the default initial width of a column from this model. Should only be queried at table creation time.

Specified by:

getColumnWidth in interface ColumnSizingTableModel

Parameters:

columnIndex - int index of the model's column whose width should be obtained

Returns:

the width, in the same units used by the TableColumn class's setWidth() method, or -1 to indicate the width should not be forced

isSizeToFit

public boolean isSizeToFit(int columnIndex)

Specifies whether setWidthToFit() should be enabled on this column

Specified by:

isSizeToFit in interface ColumnSizingTableModel

Parameters:

columnIndex - int index of the model's column whose width should be obtained

Returns:

boolean true if sizeWidthToFit() should be called on this column

compareRows

public int compareRows(int rowIndex1,
                       int rowIndex2,
                       int columnIndex)

Compare the selected column of the two rows.

Specified by:

compareRows in interface FastComparableTableModel

Parameters:

rowIndex1 - zero-based model row index of first row to compare

rowIndex2 - zero-based model row index of second row to compare

columnIndex - zero-based model column index of column to compare

Returns:

+1 if the 1st row's column is after the 2nd row's column, -1 if before, or 0 if equal precedence
