6.4. Use the Default Cache
6.4.1. Add and Remove Data from the Cache
JBoss Data Grid offers an interface that is similar to the proposed JSR-107 API to access and alter data stored in a cache.
The following procedure is an example that defines what each line entered into the DefaultCacheQuickstart.java file does:
Procedure 6.2. Add and Remove Data from the Cache
- Add an entry, replacing key and value with the desired key and value:
cache.put("key", "value"); - Confirm that the entry is present in the cache:
assertEquals(1, cache.size()); assertTrue(cache.containsKey("key")); - Remove the entry from the cache:
Object v = cache.remove("key"); - Confirm that the entry is no longer present in the cache:
assertEquals("value", v);
