Clojure中的“长数字”参数等效吗？

Question

I'm trying to call this java method from Clojure and it's throwing me "ClassCastException Cannot cast java.lang.Long to [J java.lang.Class.cast (Class.java:3003)"

public String encrypt(long... numbers) {
  return encode(numbers, alphabet_, salt_, minHashLength_);
}

What's the equivalent of calling that method from Clojure?

Answer 1

Java varargs are syntactic sugar that compiles down to a single array argument. In order to pass data from Clojure into this method, convert your collection of longs to an array with the long-array function.

(.encrypt obj (long-array [1 2 3]))
