import java.io.FileOutputStream;
import java.io.IOException;

 * An instance of this class is passed to code that generates text representation of profiling
 * results for export. It is intended that the text generating code periodically checks the size
 * of the StringBuffer it uses for storage, and if it's above some critical value, dumps it using
 * the code below. If there is an error during this process, it is not returned immediately to avoid
 * making text generator code too complex - instead the caller can eventually retrieve the error
 * using the getCaughtException() method.
