A "function type variable" can be defined in JavaFX 1.3. Wondering how such variables are defined in JavaFX 2.0. Pls. share!
From my understanding, "function type variables" are similar to "function pointers" in C/C++, but java restricts this. I may be wrong.
The closest thing normal Java currently has are interfaces, subclasses, and Reflection. There presently is no true equivalent to a function pointer. But an equivalent will be coming in Java 8 called a Lambda. JavaFX was specifically built with future support for lambdas in mind.
