Constructor Detail

PacksModel

public PacksModel(java.util.List packs,
                  java.util.List packsToInstall,
                  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:

getRowCount

public int getRowCount()

getColumnCount

public int getColumnCount()

getColumnClass

public java.lang.Class getColumnClass(int columnIndex)

isCellEditable

public boolean isCellEditable(int rowIndex,
                              int columnIndex)

getValueAt

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

setValueAt

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

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

Returns:

dfsVisit

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