StringBufferWriter.java

/**
 * A PrintWriter that does not print anything but writes everything to a stringbuffer that can then be fetched as an InputStream.<br>
 * You construct it with an output stream , e.g. the real stream to the browser that you can then later use for output.
 * This object is used by passed it into IWContext as the default output writer with iwc.setWriter(StringBufferWriter).
