how to create an ordered struct in Adobe ColdFusion and Railo - run this code here: http://www.trycf.com/scratch-pad/gist/bd92e8a7954076fd13af/railo

ordered-struct.cfm

<cfscript>
	
//In Adobe ColdFusion
//instead of structNew() or {} create a java linked hashmap
myStruct = createObject( "java", "java.util.LinkedHashMap" ).init();
//now just use it like any other struct
//NOTE: one difference though is that it will be case sensitive, myStruct["one"] will be different than myStruct["One"]
//unlike normal cf structures

//In railo you can do it like the adobe example or use this shorthand
myStruct = structNew("linked");
//again, then just use it like any other struct

//in either case, when looping over the structure the keys will always be in the order they were created

//http://classic.railo.ch/en/index.cfm?treeID=177
//you can also create a weak hash map which can have some memory performance benefits depending on what youre doing

myStruct["three"] = 3;
myStruct["two"] = 2;
myStruct["one"] = 1;
