Removing Object from Cache in Three Lines

Call method Cache.remove() to remove an object from the cache:

Cacheonix cacheonix = Cacheonix.getInstance();
Cache<String, String> cache = cacheonix.getCache("my.cache");
String removedValue = cache.remove("my.key");

Removing Collection of Objects from Cache

Cacheonix provides method Cache.removeAll() that allows to remove a set of keys from the cache:

// Get cache
Cacheonix cacheonix = Cacheonix.getInstance();
Cache<String, String> cache= cacheonix.getCache("my.cache");

// Create a key set
final Set<String> keySet = new HashSet(2);
keySet.add("my.key.0");
keySet.add("my.key.0");

// Remove keys
boolean modified = cache.removeAll(keySet);
