| net.sf.jga.fn.property.InvokeNoArgMethod
| InvokeNoArgMethod | | public class InvokeNoArgMethod extends UnaryFunctor (Code) | | Functor that invokes a no-arg method named at construction and returns the
result or null if the result is void.
Note that declaring the return type incorrectly can result in
ClassCastExceptions being thrown when the functor is invoked: the compiler
cannot check the return type of a reflectively loaded method.
