Constructor Detail

public CmdOpen()

CmdOpen

public CmdOpen(java.lang.String filterPattern)

Only allow the user to select files that match the fiven filename pattern. Needs-More-Work: This is not used yet.

Method Detail

doIt

public void doIt()

Description copied from class: Cmd

Perform whatever Cmd this Cmd is meant to do. Subclasses should override this to do whatever is intended. When the Cmd executes, it should store enough information to undo itself later if needed.

Specified by:

doIt in class Cmd

accept

public boolean accept(java.io.File dir,
                      java.lang.String name)

Only let the user select files that match the filter. This does not seem to be called under JDK 1.0.2 on solaris. I have not finished this method, it currently accepts all filenames.

Needs-More-Work: The source code for this function is duplicated in CmdSave#accept.

Specified by:

accept in interface java.io.FilenameFilter

undoIt

public void undoIt()

Description copied from class: Cmd

Undo the Cmd using information stored during its execution.

TODO Abandon this. We need the memento pattern for undo

Specified by:

undoIt in class Cmd
