public class CanReadFileFilter extends AbstractFileFilter implements java.io.Serializable
File
s 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.
