Use the member functions
Last update:
May 18, 2026
A lot of enhancements have been made to the core CFML syntax that will aid in developing ColdFusion-based applications elegantly. One of the primary enhancements is the introduction of member functions for data structure and data objects. You can now start coding in a true object oriented style.
For instance, consider the following headless function:
ArrayAppend (empArr, emp)It can now be written as:
empArr.append(emp)where 'arrayObj' is a reference to the CFArray class.
The following example depicts the new usage of member functions:
//The old way
var myArray = ArrayNew(1);
ArrayAppend(myArray, "objec_new");
ArraySort(myArray, "ASC");
// The new way
myArray.append("objec_new");
myArray.sort("ASC");
// The new way
var myProductObject = createObject("java", "myJavaclass");
myjavaList = myProductObject.getProductList();
myjavaList.add("newProduct"); // Java API
myjavaList.append("newProduct"); // CF API
myjavaList.sort("ASC");
</cfscript>Member function for the following data types are supported:
- Array
- String
- List
- Struct
- Date
- Spreadsheet
- XML
- Query
- Image
In the 2016 release of ColdFusion, there is a change in the return type for append member functions. For example,
- anystruct.append() returns appended structure
- anyarray.append() returns appended array
