An Introduction to CFCs  1 2.  An Introduction to ColdFusion Components [102] ColdFusion components (CFCs) have generated more discussion than any other aspect of the newly released ColdFusion MX server. On one end of the spectrum of opinion is the disparaging view of some that CFCs are "nothing more" than structures with user- defined functions (UDFs) attached. Equally extreme is the idea held by an impassioned few that with CFCs, Object Oriented (OO) programming has come to ColdFusion and will sweep away everything that has preceded it. [103] ColdFusion components have many similarities to objects in OO languages, but they are still quite different. For now lets simply take a look at them on their own terms, for however we may decide to classify them, CFCs are extraordinarily useful. Creating a Person CFC [104] CFCs are particularly valuable in letting developers create a software model for a category of things that exists in the world. That category can either be tangible — persons, cars, buildings—or conceptual — companies, tasks, agreements. Because concrete examples are often easier to learn, lets start our exploration by creating a CFC that models a person. 2  Discovering ColdFusion Components [105] Start by creating a directory under your MX web root to hold some example files. (Youll find it easiest if you create a directory structure of com/techspedition/CFCs directly under your web root. This will allow you to copy examples exactly as shown.) [106] Create a file called Person.cfc in the CFCs folder. (If you use another directory structure, youll need to change the code presented here to accommodate a different directory layout.) [107] In your Person.cfc file, add the <cfcomponent> tag in its barest of forms: <cfcomponent> </cfcomponent> [108] That code provides a container for all subsequent code related to our Person CFC. Note that the tag has no ...
