<p class=MsoNormal>Hi. a good idea. Though, I think it's easier to just
do<o:p></o:p></p>
<div>
<p class=MsoNormal><o:p> </o:p></p>

</div>
<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>and set aMap appropriately using Java stuff. Does
HashMap allow setter chaining? If not, you can do:<o:p></o:p></p>

code that needs to use more than one StringTemplate template instance. It mainly
saves me from having to think up separate names for the StringTemplate
variables and also seems to be more readable than a set of separate statements
since there is less non-value added text. All it would take is the
setAttribute() method to return the current StringTemplate object (i.e.
“return this;”). For now, I’ve written a simple wrapper for
StringTemplateGroup and StringTemplate classes and had to create a method named
“newTemplate()” that mimics “getInstanceOf()” and a
“setParam()” method that just calls setAttribute() but also returns
itself.<o:p></o:p></span></p>
