com.Ostermiller.util.NoCloseWriter
public class NoCloseWriter
A writer with a close method with no effect. More information about this class is available from ostermiller.org.
This class is designed to wrap a normal writer so that it can be passed to methods that write to it and may erroneously close it. This class is a workaround when the method cannot be modified because it is in a library.
