Class IterableLike

  • public class IterableLike
extends java.lang.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).

      • isIterable

        public static boolean isIterable​(java.lang.Object maybeIterable)
        Returns true if the given object is iterable.
        Parameters:
        maybeIterable - the object that might be iterable.
        Returns:
        whether IterableLike can iterate over the given object.

      • of

        public static java.util.Iterator<java.lang.Object> of​(java.lang.Object iterable)
        Given an iterable object (which may be a iterator, iterable, primitive or reference array), return an iterator over its (possibly boxed) elements.
        Parameters:
        iterable - the iterable-like
        Returns:
        an iterator of the given array's elements

      • elementTypeOf

        public static java.util.Optional<java.lang.reflect.Type> elementTypeOf​(java.lang.Object iterable)
        Given an iterable-like object, try to determine its static (i.e, without looking at contents) element type.

      • elementTypeOf

        public static java.util.Optional<java.lang.reflect.Type> elementTypeOf​(java.lang.reflect.Type type)
        Given an iterable-like type, try to determine its static (i.e, without looking at contents) element type.

      • stream

        public static java.util.stream.Stream<java.lang.Object> stream​(java.lang.Object iterable)
        Given an iterable object (which may be a iterator, iterable, primitive or reference array), return a Stream over its (possibly boxed) elements.
        Returns:
        a stream of the given array's elements

      • iterable

        public static java.lang.Iterable<java.lang.Object> iterable​(java.lang.Object iterable)
        Given an iterable object (which may be a iterator, iterable, primitive or reference array), return an iterable over its (possibly boxed) elements.
        Parameters:
        iterable - the iterable-like to create a real Iterable for
        Returns:
        the created Iterable

      • toList

        public static java.util.List<java.lang.Object> toList​(java.lang.Object iterable)
