public class EvalFunctionWrapper<ReturnType> implements Invocable<ReturnType>

EvalFunctionWrapper

All Implemented Interfaces: Invocable

Internal wrapper for functions created via eval().

The wrapper implements the reflective Invocable<R> contract because the evaluated function's parameter signature is discovered at runtime. Ordinary callbacks should use a structural function type such as (Int) -> Int.

import klyn.reflection

f = eval("""def twice(x as Int) as Int:
               return x * 2
           """)
assert f is Invocable<Int>
print(f(21))    # 42
