Hi,

I'm trying to understand what @start and @end are used for in JET templates, and also how they relate to @ include as I have seen this pattern appear in a lot of templates and do not understand what they do.

For example

<%@ include file="Class/reflectiveDelegation.override.javajetinc" fail="alternative" %>
<%@ start %>
<%if (isImplementation && (genModel.getFeatureDelegation() == GenDelegationKind.REFLECTIVE_LITERAL || genModel.isDynamicDelegation()) && (genClass.getClassExtendsGenClass() == null ||

...

<%@ end %><%//Class/reflectiveDelegation.override.javajetinc%>

Thanks

The template processor will look for the included file and, failing to
find it on the template path, will instead "include" the "alternative"
section between the @start and @end.

Hi Ed,

That makes sense, thank you.

I couldn't find the file in the repo in this example: "Class/reflectiveDelegation.override.javajetinc" and was wondering where it could be found.

Thanks,
Megan

It doesn't exist so the section between the @start/@end is always used
by default. But if you use dynamic templates (see FAQ), you can create
such a file in your template folder structure and then it will exist and
hence what you specify in that file be used instead. The idea being
that you can extend the template without copying the whole template and
just editing just one part of it.
