Ehcache/JCache and generic types

[calvin ang]

Hi there,

Is there any way to configure a cache whose value type is a generic using either the Ehcache or JCache APIs? In other words, I'd like to do something like the following:

public class BasicCache<T>

{

private void foo()

{

CachingProvider provider = Caching.getCachingProvider(fullyQualifiedProviderName);

     CacheManager cacheManager = provider.getCacheManager();
     configuration = new MutableConfiguration<String, T>()

     .setTypes(String.class, T.class)....

} 

 }

T.class is not permissible and from what I understand, there is no "good" workaround for it. (I'm a C# guy so ordinarily something like the above would be permissible.)

Is there any way possible to get around this limitation? Maybe it _is_ indeed possible and I am missing something?

As you might have guessed, I'm trying to write a wrapper around the API. 

Ehcache 3.1; JDK 1.7

Thanks!

Right, in Java, the generic type gets erased... 

But you could pass in the T's class instance, say to the constructor as in:

BasicCache<Foo> basicCache = new BasicCache(Foo.class);

Where the constructor would that a Class<T>:  BasicCache(Class<T> valueType);

You could then use the Class<T> field to create the actual cache instance in foo();
