All Implemented Interfaces:

java.io.FilenameFilter

public class ConcreteFilenameFilter

extends java.lang.Object

implements java.io.FilenameFilter

A case-insensitive, concrete implementation of java.io.FilenameFilter. Patterned after an example in Bruce Eckel's "Thinking in Java". Example:

	// Get a list of XML files in a directory
	ConcreteFilenameFilter xmlFilter = new ConcreteFilenameFilter(".xml");
	File fileList[] = prefsDir.listFiles(xmlFilter);
	if (fileList == null || fileList.length < 1) {
	    throw new IOException("'" + prefsDirString + "' has no .xml files in it!");
	}
