Summary

ColdFusion Components are object-type building blocks used to create reusable, scalable, tiered, and structured code. CFCs are created using a set of special tags and are saved in .cfc files. CFCs may be invoked in several ways: invoking them as objects allows them to be loaded into persistent scopes. CFCs support inheritance and constructors, and they have an internal scope that persists as long as the CFC persists. CFCs can be secured on a per-method basis, and they can self-document and be introspected.
