On the "Development" update provider, you can find the latest Railo Beta release (
That release not only bring a lot of bug fixes, it also has some new features.

Iterator (Callback/Closure) Functions
In the last release we already added a couple of new iterator functions to Railo (arrayEach,arrayEvery,arrayMap,...), in this release we even extended that list with iterator functions for the "query" and  "string lists".
So we have new the following functions:
- QueryEach
- QueryEvery
- QueryFilter
- QueryMap
- QueryReduce
- QuerySome
- ListEach
- ListEvery
- ListFilter
- ListMap
- ListReduce
- ListSome

We had a vivid discussion about how the argument scope of the udf/closure called with the query functions should look like, again thx to everybody for that!
We decided not do add a new "QueryColumn" type to Railo and simply pass the current row as a struct to the closure/udf and the hole query with the 3th argument
(We will do a detailed blog post about this in the near future).
Of Course all the new query functions can also be used "member functions" (Example: myQuery.each(function(struct row,numeric rowNumber,query query){dump(row)});).

The "List" Functions work the same way as the array functions, with the different that you call them with a string list and not a array ;-)
ATM the list functions are not supported as "member functions" (more below).

In the last release we also added iterator functions that are not specific to a type, functions that can handle all kind of "collections", the same way <cfloop collection="..."> can.
problem was that the short names of this functions getting in conflict with existing  UDFs defined by existimg CFML applications, for example the function "map" that is also used as UDF in "wirebox".
So we decided to rename this functions to "collection...", so for example "Map" is now renamed to "collectionMap".

Of course all this new iterator functions (except ...reduce) are supporting parallel execution like the existing ones!

Member Functions
Railo is supporting member functions for some time now, for the types [array,date,struct,query]. In the current beta release ACF has adopted this feature and they added additional support for the type string,"list" and image as well.
In this release we added support for "string" as well (and the next release will support "image"), what we not have is support for "list" functions, because it was not sure at the time of the release how they will look like in ACF (current implementation is not ... very good and they plan to change it for the next beta release).
Until the final release all of this is not curved in stone, so please feel free to eat it alive!

we also added new member function for strings (startsWith,endsWith,isEmpty)

GetBuiltInFunction (experimental)
This new function is returning you any built in function as a object that can be used the same way as a closure/udf.
function test(function finder,string str,string sub){
   return finder(sub,str);
if(custom) func=function (string sub, strig str){...};
else if(caseSensitive) func=getBuiltinFunction("find");
else func =getBuiltinFunction("findNoCase");

Function Reference Documentation in Admin
in the function reference in the Railo Administrator you can now filter functions by keywords, so for example you choose "iterator" to list only the iterator functions.

Unary operators
Thx to Adam Cameron we have uncovered a bug with all unary operators that is fixed with this release.

This is the last beta release for 4.2, so please report any problem you have with it
Have fun
