GM_SESSION_CACHE

Keeps session information during user-login time.

GM_SERVICE_CACHE

Fill with service class information when application server started.

GM_MESSAGE_CACHE

Fill with message id and message language data when application server started.

HOW TO Writing a simple cache mechanism

Create a class and implement GMCacheLoader.
Add unimplemented methods. (load(), lookup(String arg0)).
When application server started load() function invokes. Fill your cache on load() function.
If key cannot find on load() function, cache manager invokes lookup(String arg0) function.
Put your cache to GMCacheConfiguration.xml. You will call this cache from a GraymoundService with name attribute. (TEST_CACHE)

<cache name="TEST_CACHE">
<manager class="com.graymound.cache.GMCacheManagerLocal"/>
  <loaders>
   <loader class="com.obss.tutorial.TestCache"/>
  </loaders>
</cache>

Here is simple cache code;

public class TestCache implements GMCacheLoader{
 public Map<String, Object> load() {
  Map<String, Object> map = new HashMap<String, Object>();
  map.put("TestData", "212");
  return map;
 }
 public Object lookup(String arg0) {
  HashMap<String, String> lMap = new HashMap<String, String>();
  lMap.put("TestInfo", "2155");
  return lMap;
 }
}

HOW TO Get a value from cache

GMCache cache = GMCacheFactory.getInstance().getCache("TEST_CACHE");
String value = (String) cache.get("TestData ");

HOW TO Put a value to cache

GMCache cache = GMCacheFactory.getInstance().getCache("TEST_CACHE");
cache.put("TestData","322");
