|
+--org.apache.avalon.excalibur.io.InvertedFileFilter
- All Implemented Interfaces:
- java.io.FilenameFilter
- public class InvertedFileFilter
- extends java.lang.Object
- implements java.io.FilenameFilter
This takes a FilenameFilter as input and inverts the selection.
This is used in retrieving files that are not accepted by a filter.
Eg., here is how one could use InvertedFileFilter
in conjunction with
ExtensionFileFilter
to print all files not ending in
.bak
or .BAK
in the current directory:
File dir = new File(".");
String[] files = dir.list(
new InvertedFileFilter(
new ExtensionFileFilter( new String[]{".bak", ".BAK"} )
)
);
for ( int i=0; i<files.length; i++ )
{
System.out.println(files[i]);
}
