Examples of ch.inftec.ju.util.IOUtil

ch.inftec.ju.util.IOUtil
Utility class containing I/O related helper methods. Methods that depend on a charset or on a text Reader are not static. In this case, a new IOUtil instance must be created using either the default charset or an explicit charset (as specified in the constructor).
The IOUtil class converts line endings to a single LF character ('\n'), regardless of the actual line feed policy used in the source file. @author tgdmemae
