static JMenuBar joshua.ui.tree_visualizer.DerivationBrowser.createJMenuBar

(

)

[static, private]

Creates the menu bar for the chooser frame. We put this in a seperate method so that it can be easily found and changed if need be.

Returns:

the menu bar for the chooser frame

Here is the caller graph for this function:

static void joshua.ui.tree_visualizer.DerivationBrowser.initializeJComponents

(

)

[static, private]

Initializes the various components in the chooser frame. The two JLists are laid out, and a menu bar is attached.

Here is the call graph for this function:

Here is the caller graph for this function:

static void joshua.ui.tree_visualizer.DerivationBrowser.main

(

String[]

argv

)

[static]

The main method.

Parameters:

argv	command-line parameters. Can specify the source or target file.

Here is the call graph for this function:

static void joshua.ui.tree_visualizer.DerivationBrowser.populateSourceList

(

)

[static, private]

Displays the source-side sentences in their list. This method is called whenever the source- side file is changed.

Here is the caller graph for this function:

static void joshua.ui.tree_visualizer.DerivationBrowser.populateTargetList

(

)

[static, private]

Displays the candidate translations for the current source sentence in their list. This method is called whenever the source list's selected value is changed.

Here is the caller graph for this function:

static void joshua.ui.tree_visualizer.DerivationBrowser.setNBestLists

(

)

[static, private]

Reads in the currently set target file and organizes it into seperate n-best lists. Each n-best list corresponds to a different source sentence.
