public class FunctionFactory

extends Object

The FunctionFactory instanciates Function objects. There are 6 static getFunctions objects in this class, which correspond to 6 different kind of Function objects. The function factory was more important in the 1.7 version of MMBase. Since MMBase 1.8 there are FunctionProviders, so often, it is just as easy and straight forward to simply call the getFunction method on the relevant FunctionProvider (like FunctionSet, Cloud, Module, or Node) or to simply instantiate the Function object (e.g. BeanFunction)

Since:

MMBase-1.7
