Read up on 'duck typing' - Sean > Corfield has a nice powerpoint that outlines this concept. You have to > remember that Coldfusion does not enforce strict typing; Coldfusion is not > Java!! The basic idea is that if you pass in a value (be it a string, > query, object, whatever) and it works within your code, it is of the > correct type (if it walks like a duck, quacks like a duck, it's a duck!). > If you pass in a numeric value to a function that is expecting a string, > it's going to work. If you pass in an object with properties x, y, and z > to a function expecting an object with properties x, y, and z it's going > to work. If you were to restrict your function to only accept objects with > a type of cfc.exampleObj, you are unnecessarily restricting the possible > input of your function as well as creating a performance loss by making > your function check the object's type in the first place! > > As defined by Wikipedia - http://en.wikipedia.org/wiki/Duck_typing > > Jake Pilgrim ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Create robust enterprise, web RIAs.
