Using DynaCache APIs to operate the cache

Obtaining a reference to the cache object:

InitialContext ctx = new InitialContext();
DistributedMap myCustomCache = (DistributedMap) 
ctx.lookup(“services/cache/MyCustomCache”);

Once a reference to the cache object is obtained, the put() methods can be used to add to the cache. Depending on the cache configuration, the method will update the local and remote caches.

myCustomCache.put("cacheId", myCacheEntryObject )

final int priority = 1;
// the time in seconds that the cache entry should remain in the cache. The default value is -1 and means the entry does not time out.
final int timeToLive     =  1800;
// the time in seconds that the cache entry should remain in the cache if not accessed.
// Inactivity is supported by the local cache but not by the remote cache
final int inactivityTime = 900
// Not supported
final int sharingPolicy = 0;
final String [] dependencyIds = new String [] {"dependencyId1", "dependencyId2"};

myCustomCache.put("cacheId", myCacheEntryObject, priority, timeToLive, inactivityTime, sharingPolicy, dependencyIds );

Use the get() interface to read an object back from the cache. If local and remote caching is enabled, the HCL Cache will first attempt to load the object from the local cache, and then from the remote cache only if the specified cache ID was not found in the local cache.

Object cachedObject = myCustomCache.get(“cacheKey”);

The clear() method empties the cache. The invalidate() method removes using a dependency ID or a cache ID.

myCustomCache.clear();
…
myCustomCache.invalidate(“dependencyId1”);
