org.apache.velocity.tools.generic.ListTool

Tool for working with Lists and arrays in Velocity templates. It provides a method to get and set specified elements. Also provides methods to perform the following actions to Lists and arrays:

Check if it is empty.
Check if it contains a certain element.

 Example uses: $primes                    -> new int[] {2, 3, 5, 7} $lists.size($primes)        -> 4 $lists.get($primes, 2)      -> 5 $lists.set($primes, 2, 1)   -> (primes[2] becomes 1) $lists.get($primes, 2)      -> 1 $lists.isEmpty($primes)     -> false $lists.contains($primes, 7) -> true Example tools.xml config (if you want to use this with VelocityView): <tools> <toolbox scope="application"> <tool class="org.apache.velocity.tools.generic.ListTool"/> </toolbox> </tools>

This tool is entirely threadsafe, and has no instance members. It may be used in any scope (request, session, or application).
