Hi,
your question is not clear. You seem to be familiar with some other programming
or scripting language - please get up-to-date with Java for the application
side, also look at the examples in the Velocity developers guide:
http://velocity.apache.org/engine/releases/velocity-1.6.2/developer-guide.html
and Velocity syntax for the template side; read the Velocity users guide:
http://velocity.apache.org/engine/releases/velocity-1.6.2/user-guide.html
If your function is part of a Java class, place an instance into the Velocity
context either with the ToolboxManager or using Java code in your application
before merging:
context.put("Functions", new Function());
(more at:
http://velocity.apache.org/engine/releases/velocity-1.6.2/developer-guide.html#How_Velocity_Works
)
and use it in your template:
#set( $retvalue = $Functions.function() )
If you want to define scripted code in your Velocity template (called macros),
you can do:
#macro( Function )
...do something wise
#end
and use it in your template:
#set( $retvalue = "#Function()" )
Please note that macros can only return strings! So if you need variant return
types, you need a Java class with a corresponding method (in which case a
"void" parameter does not make sense - how will it differentiate what to
return?).
Hope this helped,
Christoph
