Class WMLWriter

java.lang.Object
  org.apache.tapestry.AbstractMarkupWriter
      org.apache.tapestry.wml.WMLWriter

All Implemented Interfaces:

IMarkupWriter

Direct Known Subclasses:

NestedWMLWriter

public class WMLWriter
extends AbstractMarkupWriter

This class is used to create WML output.

The WMLResponseWriter handles the necessary escaping of invalid characters. Specifically, the '$', '<', '>' and '&' characters are properly converted to their WML entities by the print() methods. Similar measures are taken by the AbstractMarkupWriter.attribute(String, String) method. Other invalid characters are converted to their numeric entity equivalent.

This class makes it easy to generate trivial and non-trivial WML pages. It is also useful to generate WML snippets. It's ability to do simple formatting is very useful. A JSP may create an instance of the class and use it as an alternative to the simple-minded <%= ... %> construct, espcially because it can handle null more cleanly.
