Class IterableLike

java.lang.Object
org.jdbi.v3.core.internal.IterableLike
public class IterableLike extends Object
Implements Iterator methods for unidentified arrays and Iterable things that do not have a more specific type than Object. Note that its elements will be returned as Object, primitives included (will be autoboxed).
