Returns a list that applies function to each element of fromList .

Usage

From source file:com.google.gxp.compiler.base.Util.java

/**
 * Given a function and a list, returns a list such that each element of the
 * result is the corresponding element of the input list mapped through the
 * input function.  Unlike Lists.transform the result is <em>not</em> a lazy
 * view, and null elements in the result are disallowed.  This is very
 * similar to the map function in Python and Scheme, except the parameters
 * are reversed for consistency with Lists.transform.
 *
 * @throws NullPointerException if any of resulting elements would be null.
 *//*from  ww  w  .j a  v a2  s . c o m*/
public static <K, V> ImmutableList<V> map(List<K> fromList, Function<? super K, ? extends V> function) {
