public class CanReadFileFilter extends AbstractFileFilter implements java.io.Serializable
Files that can be read.
Example, showing how to print out a list of the current directory's readable files:
File dir = FileUtils.current();
String[] files = dir.list(CanReadFileFilter.CAN_READ);
for (String file : files) {
System.out.println(file);
}
Example, showing how to print out a list of the current directory's un-readable files:
File dir = FileUtils.current();
String[] files = dir.list(CanReadFileFilter.CANNOT_READ);
for (String file : files) {
System.out.println(file);
}
Example, showing how to print out a list of the current directory's read-only files:
File dir = FileUtils.current();
String[] files = dir.list(CanReadFileFilter.READ_ONLY);
for (String file : files) {
System.out.println(file);
}
Serialization is deprecated and will be removed in 3.0.
