cfcomponent 85
cfcomponent
Description
Creates and defines a component object; encloses functionality that you build in CFML and
enclose within
cffunction tags. This tag contains one or more cffunction tags that define
methods. Code within the body of this tag, other than
cffunction tags, is executed when the
component is instantiated.
A component file has the extension CFC and is stored in any directory of an application.
A component method is invoked in the following ways:
• Within the cfinvoke tag in a ColdFusion page
• Within a URL that calls a CFC file and passes a method name as a URL parameter
• Within the cfscript tag
• As a web service
• From Flash code
