write

public void write(java.net.URI f,
                  URIChooser chooser)
           throws java.io.IOException

Writes the view to the specified uri.

Parameters:

f - The location where to write the view.

chooser - The chooser which was used for selecting the URI. This parameter is null if no chooser was used.

Throws:

java.io.IOException

read

public void read(java.net.URI f,
                 URIChooser chooser)
          throws java.io.IOException

Reads the view from the specified uri.

Parameters:

f - The location where to write the view.

chooser - The chooser which was used for selecting the URI. This parameter is null if no chooser was used.

Throws:

java.io.IOException

clear

public void clear()

Clears the view.

canSaveTo

public boolean canSaveTo(java.net.URI file)

Description copied from interface: View

Returns true, if this view can be saved to the specified URI. A reason why the view can't be saved to a URI, is that the view is unable to write to a file-URI with the given filename extension without losing data.

The SaveAction uses this method to decide, whether to display a save dialog before saving the URI.

Specified by:

canSaveTo in interface View

Overrides:

canSaveTo in class AbstractView

Parameters:

file - An URI. If this parameter is null, a NullPointerException is thrown.
