Answer 2

+4 A:

not possible, since there's no "static method" in ColdFusion.

The <cfinvoke> line in your question is the same as:

myReturnVar = CreateObject("component", "MyComponent").myStaticMethod(arg1="blah");

Thanks, I thought that might be the case but wasn't sure.

One thing to keep in mind is that if you were using CreateObject to make a JAVA object then you would do the same thing as here....you have to make a static reference to the class (by NOT calling init)....before calling the static method.

Also, you should prefer this over <cfinvoke> because it's more efficient for CF internally even though that may seem counter intuitive.

@Bialecki really? why is it more efficient?

Henry 2010-01-16 14:32:08

@Henry somewhere in the CF documentation they mention that creating a component and calling a method on it is more efficient than <cfinvoke>. Very odd, I know, but it was a bug in CF 7, don't know if it was fixed in 8 or 9. I'll poke around for a link to it.

If you find it, I would be interested in reading about it too. The only performance recommendation I was aware of regarded reuse. ie It is more efficient to create once, and reuse an object multiple times, rather than creating a new object each time ie Calling <cfinvoke component="MyComponent" method="..."> over and over.

Answer 3

+3 A:

You need to create the object first.

<cfset MyComponent = createObject("component","MyComponent") />
<cfset myReturnVar = MyComponent.myMethod(blah) />

This is the same as what Henry wrote, not sure why it was downvoted
