Or use the Map, and use a fixed value (or ignore it) On 25 January 2018 at 16:44, Alex Fedotovwrote: > You can probably use a hack with classloader.

Re: Create an empty java.util.Set in VTL
You can probably use a hack with classloader. Along the lines of: #set($x = "1".getClass().getClassloader().findClass("java.uti.HashSet").newInstance()) Alex On Thu, Jan 25, 2018 at 11:30 AM, Christopher Schultz < ch...@christopherschultz.net> wrote: > -BEGIN PGP SIGNED MESSAGE- > Hash: SHA256 > > All, > > If I want to create a new empty array/collection, I can do something > like this: > > #set($array = []) > > If I want to create a new Map, I can do this: > > #set($map = {}) > > Is there a way to create a new Set? > > I'd like to use a set because: > > 1.

Re: Create an empty java.util.Set in VTL
Not with the default syntax and context. If you can control the context, you can put an utility that can create any type of collection: random sets, linked sets, ordered sets, linked maps, ordered maps...

Create an empty java.util.Set in VTL
-BEGIN PGP SIGNED MESSAGE- Hash: SHA256 All, If I want to create a new empty array/collection, I can do something like this: #set($array = []) If I want to create a new Map, I can do this: #set($map = {}) Is there a way to create a new Set? I'd like to use a set because: 1. I want to use this object as a sort of scratch-area to know what work I've done before and 2. I'm going to be consulting it a lot using Set.contains(object) so something other than ArrayList/LinkedList will be much faster Thanks, - -chris -BEGIN PGP SIGNATURE- Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQJRBAEBCAA7FiEEMmKgYcQvxMe7tcJcHPApP6U8pFgFAlpqBjsdHGNocmlzQGNo cmlzdG9waGVyc2NodWx0ei5uZXQACgkQHPApP6U8pFisIQ//VqqfK6GzyxnQZ9qK QvQREhkJoafg5X7n4d1M7pfG99qGTlGhrLXwO8YD0Qhpj0v7QKbJbi3LsjmwIVQT 4wvMXO7cBLXbB3bdc640ITylettTqKODTPk/KBIKq4nvSUVMGKvn/q/NlrZFX776 11SBC2VLcU7ujzaglL+F/xlF0C1ZS1UAFQlBVcRxT48C44dGOGSYVOu9UmYPvxpk 4ExrjKwkuTb6zsXn/Nwn1d/K7jB+Cqx77KDNOj0eBQK5POHZa/cC/W0z9uVdlUJg oVOwxITiEyTd2XmEFa1OjnU4yrZkU+N+wPzsFxgNwKzWSTC4CsBjIw2oSh4cOEqy gU7HRlCQMRhhBAYD6M7a8wvI60/UI/klb7aB1wOwt74A2/jtwx3M2mBKoYFYTx3X sfXS1lRtiXLtmooe50wHBvHBhvWXHkLE0dRETtgsLH/QiFgpG3xjoLPHkm6nL/60 4KJ5kt/a8afm1dBgcSc4Y6eXrAr0XQl9vREPfGWbcQs3h+azJ2L1leoEg2jnA3gh oytTF7HmuoX4cYqF1SLeLlMlRJdaAzayZYRwWeB739t7W7iRBzackNzTZyWfNqVD FRTv3vmsl477J9KI05rH7qlmowFL0QmwP6WeRPtOpQq8gDFKhRcGcoPXRtT6aXke VGfV9fj4L7nJBBUkOWtSfQU7WuY= =61WB -END PGP SIGNATURE- - To unsubscribe, e-mail: user-unsubscr...@velocity.apache.org For additional commands, e-mail: user-h...@velocity.apache.org
