sfussenegger / AsyncCacheLoader.java

Created March 21, 2013 10:32

A simple Google Guava CacheLoader implementation that submits Function execution to an ExecutorService thus making a LoadingCache asynchronous. Note that threads won't be wasted waiting (at least as long as one doesn't wait on a Future's get() method).

	import java.util.concurrent.Callable;
	import java.util.concurrent.ExecutorService;
	import java.util.concurrent.Future;

	import com.google.common.base.Function;
	import com.google.common.cache.CacheLoader;

	public class AsyncCacheLoader<K, V> extends CacheLoader<K, Future<V>> {

	private final ExecutorService _executor;
