Examples of java.io.ByteArrayOutputStream.reset()

java.io.ByteArrayOutputStream.reset()
Reset this ByteArrayOutputStream to the beginning of the underlying byte array. All subsequent writes will overwrite any bytes previously stored in this stream.

         result.setChild(new Widget());
         result.getChild().setValue("foo");
         result.getChild().setSecret("bar");


         // Reset our output stream so we can re-use it
         out.reset();


         // Now we're going to constrain result.child's secret field
         c.setConstraints(Arrays.asList(new String[] { "child.secret" }));
         MarshalUtils.marshalResult(c, out);

         val.setValue("foo");
         val.setSecret("bar");
         result.getWidgetMap().put("foo", val);


         // Reset our output stream again
         out.reset();


         // Constrain the "secret" field of the widgetMap map's values (sounds
         // confusing, I know...)
         c.setConstraints(Arrays.asList(new String[] { "widgetMap[value].secret" }));
         MarshalUtils.marshalResult(c, out);
