T - Type of the Writer passed in the constructor.public class CloseOnceWriter<T extends Writer> extends FilterWriter
A CloseOnceWriter wraps some other Writer
preventing multiple invocations of the method close().
It forwards all requests to the contained writer, except the close() method that is passed only one time to the underlying stream.
This is useful with some non conforming Writer that don't allow
close() to be called multiple times.
