Constructor Detail

TFileTreeModel

public TFileTreeModel(@CheckForNull
                      net.java.truevfs.access.TFile root,
                      @CheckForNull
                      java.io.FileFilter filter,
                      java.util.Comparator<? super net.java.truevfs.access.TFile> comparator)

Creates a new TFileTreeModel which browses the specified root file. If file is an instance of TFile, its archive detector is used to detect any archive files in the directory tree.

Parameters:

root - The root of this TFileTreeModel. If this is null, an empty tree is created.

filter - Used to filter the files and directories which are present in this TreeModel. If this is null, all files are accepted.

comparator - A comparator for TFile instances or super classes. This must not be null.

Throws:

java.lang.NullPointerException - If comparator is null.

java.lang.IllegalArgumentException - If root isn't null and comparing it to itself didn't result in 0.

java.lang.ClassCastException - If root isn't null and comparator isn't a Comparator for TFile or super class instances.
