Class UICFileFilter

java.lang.Object
  javax.swing.filechooser.FileFilter
      uic.widgets.filechooser.AbstractFileFilter
          uic.widgets.filechooser.UICFileFilter

All Implemented Interfaces:

FileFilter

public class UICFileFilter
extends AbstractFileFilter

A fileFilter that allows you to filter files on regular expressions. Notice that this class also combines an abtract javax.swing.filechooser.FileFilter (with no implementation, which effectively makes it the same as an interface) and the java.io.FileFilter is a real interface, with the same methods but has the first has no reference to the second.

Lets just say that the good authors at Sun missed the obvious; one should extend or implement the other. This class therefor is a good basis to extend further file filters from.

Since:

2.0

Constructor Detail

UICFileFilter

public UICFileFilter(String description,
                     String regularExpression)
              throws PatternSyntaxException

Create a FileFilter which matches any file on a regular expression.

Parameters:

description - the description which will be used in the combo-box of the filechooser.

regularExpression - a correctly formatted regular expression which will be used case incensitive on each filename. Regular expressions are very powerfull and can quickly get unreadable to the untrained eye. Common pitfalls: 1) you need to specify the full name, not a part of it. Add .*around your regular expression if you want just a part of the string.

Throws:

PatternSyntaxException

Parameters:
