DigitalTableModel

public DigitalTableModel(int inPinNumber,
                         int outPinNumber,
                         int stateNumber)

DigitalTableModel constructor.

Parameters:

inPinNumber - Number of input pins to store data on

outPinNumber - Number of output pins to store data on

stateNumber - Number of internal states (if zero we are producing a truth table)

Method Detail

isCellEditable

public boolean isCellEditable(int r,
                              int c)

The only editable cell is the next state column in a state table

Parameters:

r - Row index

c - Column index

Returns:

true if the cell is editable

setValueAt

public void setValueAt(java.lang.Object value,
                       int r,
                       int c)

selectCell

public void selectCell(int r,
                       int c)

Call this method when a cell has been selected so it's value may be toggled

Parameters:

r - Row number

c - Column number

setColumnHeader

public void setColumnHeader(int c,
                            java.lang.String label)

Changes a column name

Parameters:

c - Column

label - New label to use for that column

getNextStateColumn

public int getNextStateColumn()

Returns:

the column number of the column which stores the next state

getInitialStateColumn

public int getInitialStateColumn()

Returns:

the column number of the column which stores the initial state

getRowCount

Returns:

The number of rows in the table

getColumnCount

public int getColumnCount()

Returns:

The number of columns in the table

getInPinCount

public int getInPinCount()

Returns:

The number of input pins in the chip

getValueAt
