Class MastersLoadingCache

java.lang.Object
  com.google.common.cache.AbstractCache<K,V>
      com.google.common.cache.AbstractLoadingCache<Image,Master>
          org.jclouds.virtualbox.functions.MastersLoadingCache

All Implemented Interfaces:

com.google.common.base.Function<Image,Master>, com.google.common.cache.Cache<Image,Master>, com.google.common.cache.LoadingCache<Image,Master>

@Singleton
public class MastersLoadingCache
extends com.google.common.cache.AbstractLoadingCache<Image,Master>

A LoadingCache for masters. If the requested master has been previously created this returns it, if not it coordinates its creation including downloading isos and creating cache/config directories. This also implements Supplier in order to provide jetty with the current image (only one master can be created at a time).
