public class GateTableModel

extends javax.swing.table.AbstractTableModel

This class holds the actual quantum circuit. Gates are represented by GateContainer objects to allow gate groups. The actual gate information is stored in a mathlib variable of the type Gate and each GateContainer has a reference to a Gate variable. The GateTableModel does not autonomously react to MathlibEvents, but rather the GateTable class is taking care of this.

GateContainer	getGateContainer(java.lang.String name) returns the gateContainer with the given name, null otherwise
int	getRowCount() returns the dimension of the gates (= qubit number)
java.lang.Object	getValueAt(int row, int col) returns the gateContainer in the model which corresponds to the column the paramter row is ignored.
boolean	isCellEditable(int row, int col) returns true if the cell is a preparation operation
void	moveQubit(int fromRow, int toRow) moves a qubit by exchanging the charakters in the gate_descr for each gateContainer
void	removeGateContainer(GateContainer gateContainer) removes a given gateContainer
void	removeGateContainer(int column) removes a given gateContainer
void	removeQubit(int row) remove a qubit, i.e. for each gateContainer in the model the gate_descr is modiefied.

Field Detail

gateContainers

protected java.util.Vector gateContainers

holds names of gate variables

Constructor Detail

GateTableModel

public GateTableModel()

creates a GateTableModel. A gate is represented by a GateContainer. The GateContainers are saved in an internal vector, but the gates themselves are Gate objects represented by a variable in the Mathlib class.

Method Detail

addGateContainer

public void addGateContainer(GateContainer gateContainer)

adds a GateContainer to the GateTableModel

Parameters:

gateContainer - the gateContainer object to add

getColumnCount

public int getColumnCount()

gets the number of top level gateContainers (= column count)

Overrides:

getColumnCount in class javax.swing.table.AbstractTableModel

getRowCount

public int getRowCount()

returns the dimension of the gates (= qubit number)

Overrides:

getRowCount in class javax.swing.table.AbstractTableModel

getColumnClass

public java.lang.Class getColumnClass(int c)

returns always the GateContainer class

Overrides:

getColumnClass in class javax.swing.table.AbstractTableModel

getColumnName

public java.lang.String getColumnName(int column)

returns the top level name of the gateContainer in column column

Overrides:

getColumnName in class javax.swing.table.AbstractTableModel

getValueAt

public java.lang.Object getValueAt(int row,
                                   int col)

returns the gateContainer in the model which corresponds to the column the paramter row is ignored.

Overrides:

getValueAt in class javax.swing.table.AbstractTableModel

getGateContainer

public GateContainer getGateContainer(java.lang.String name)

returns the gateContainer with the given name, null otherwise

isCellEditable

public boolean isCellEditable(int row,
                              int col)

returns true if the cell is a preparation operation

Overrides:

isCellEditable in class javax.swing.table.AbstractTableModel

setValueAt

public void setValueAt(java.lang.Object value,
                       int row,
                       int col)

method is called in the process of editing a cell. It only is invoked for the preparation operation

Overrides:

setValueAt in class javax.swing.table.AbstractTableModel

contains

public boolean contains(GateContainer gateContainer)

checks whether a given gateContainer is contained by the GateTableModel

removeGateContainer

public void removeGateContainer(GateContainer gateContainer)

removes a given gateContainer

removeGateContainer

public void removeGateContainer(int column)

removes a given gateContainer

removeQubit

public void removeQubit(int row)

remove a qubit, i.e. for each gateContainer in the model the gate_descr is modiefied. A plausibility check is run afterwards.

moveQubit

public void moveQubit(int fromRow,
                      int toRow)

moves a qubit by exchanging the charakters in the gate_descr for each gateContainer

addQubit

public void addQubit()

adds a qubit by adding a '-' to the gate_descr of each gate contained by the gateContainers in this model.

tableUpdated

public void tableUpdated()

wraps the fireTableDataChanged() method....
