          PacksPanelInterface panel)

Method Detail

reverseDeps

private void reverseDeps()

Creates the reverse dependency graph

initvalues

private void initvalues()

propRequirement

private void propRequirement(java.lang.String name)

getPos

private int getPos(java.lang.String name)

Given a map of names and Integer for position and a name it return the position of this name as an int

Returns:

position of the name

getRowCount

public int getRowCount()

getColumnCount

public int getColumnCount()

getColumnClass

public java.lang.Class getColumnClass(int columnIndex)

Specified by:

getColumnClass in interface javax.swing.table.TableModel

Overrides:

getColumnClass in class javax.swing.table.AbstractTableModel

isCellEditable

public boolean isCellEditable(int rowIndex,
                     int columnIndex)

Specified by:

isCellEditable in interface javax.swing.table.TableModel

Overrides:

isCellEditable in class javax.swing.table.AbstractTableModel

getValueAt

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

setValueAt

public void setValueAt(java.lang.Object aValue,
              int rowIndex,
              int columnIndex)

Specified by:

setValueAt in interface javax.swing.table.TableModel

Overrides:

setValueAt in class javax.swing.table.AbstractTableModel

refreshPacksToInstall

private void refreshPacksToInstall()

updateDeps

private void updateDeps()

This function updates the checkboxes after a change by disabling packs that cannot be installed anymore and enabling those that can after the change. This is accomplished by running a search that pinpoints the packs that must be disabled by a non-fullfiled dependency.

dfs

private int dfs(int[] status)

We use a modified dfs graph search algorithm as described in: Thomas H. Cormen, Charles Leiserson, Ronald Rivest and Clifford Stein. Introduction to algorithms 2nd Edition 540-549,MIT Press, 2001

dfsVisit

private int dfsVisit(Pack u,
           int[] status,
           boolean wipe)
