Examples of org.apache.wicket.response.StringResponse

org.apache.wicket.response.StringResponse
Response object that writes to a StringWriter. If the StringResponse is later converted to a String via toString(), the output which was written to the StringResponse will be returned as a String. @author Jonathan Locke
