Functions
Description of functions in Drizzle
Functions in Drizzle are defined using the
def keyword.def multiply_message(msg: str, times: int = 5) {
to_print = msg * times
println(to_print)
}
# In this example we show that Drizzle supports default params
multiply_message('a') # Prints 'aaaaa'
multiply_message('a', 3) # Prints 'aaa'
Drizzle also supports simple one line functions;
def multiply_message(msg: str, times: int = 5) = println(msg * times)
Return types of the function are shown through the use of the
-> operatordef test() -> int = return 3
If no return type is explicitly described, the
null type is assumed to be the return type. The null type is returned from a function in 3 cases: 1. When there's no return statement in the function. 2. When there's an empty return statement in the function. 3. When null is explicitly returned from the function.Last modified 3yr ago
