How to get all values from guava LoadingCache without passing any keys

Dave :

I am using Guava LoadingCache to cache some of the results. Using load method I fetch results from other source and put into cache using 'put(key,value)'. Now the problem I am trying to solve is: I want to get all the available results in that cache with out passing any keys. Because I am interested in taking all the values presented in the cache at that time regardless of any specific keys.

getall(Iterable<?> keys) or getAllPresent(Iterable<?> keys) methods are there but those are expecting the keys to be passed.

Xaerxess :

You can use (Loading)Cache#asMap view and operate on returned ConcurrentMap. There's nice description on Guava wiki page:

You can view any Cache as a ConcurrentMap using its asMap view, but how the asMap view interacts with the Cache requires some explanation.

• cache.asMap() contains all entries that are currently loaded in the cache. So, for example, cache.asMap().keySet() contains all the currently loaded keys.
