What Are CFX Tags?

CFX tags are custom tags written against the ColdFusion Extension Application Programming Interface. Generally, you create a CFX if you want to do something that is not possible in CFML, or if you want to improve performance of a repetitive task. CFXs can do the following:

Handle any number of custom attributes.
Use and manipulate ColdFusion queries for custom formatting.
Generate ColdFusion queries for interfacing with non-ODBC based information sources.
Dynamically generate HTML to be returned to the client.
Set variables within the ColdFusion application page from which they are called.
Throw exceptions that result in standard ColdFusion error messages.

You can build CFXs using C++ or Java.

Note

To use a CFX, you must register it in the ColdFusion Administrator, as described in "Registering CFXs".
