LoaderMethodCache

Thread Local cache for a method's return value.

How it works?

• Wraps itself around a method by using Guice AOP's Method Interceptor.
• Uses a Manager which holds a Thread Local map.
• Manager holds the wrapped method's result on Thread local map.
• Returns the result from thread local when queried repeatedly.

How to use?

• Apply @CacheMethod annotation over the method you want to be cached.
• Call MethodCacheManager.init() before calling the method which needs to be cached.
• After finishing all the processing on thread, call MethodCacheManager.flush() for clearing the cache.

Best Usecases

• Multiple external GET calls on resource which is not bound to change across the thread's processing time.

Limitations

• Can be used only on resources which are not bound to change across the thread's time.
• Should be used only on GET resources with a non-void return type.
• Cache Invalidation is not possible within the thread's time.
