Package org.cache2k.config

Class CacheTypeCapture<T>

java.lang.Object

org.cache2k.config.CacheTypeCapture<T>

All Implemented Interfaces:

CacheType<T>

public class CacheTypeCapture<T>
extends Object
implements CacheType<T>

Helper class to capture generic types into a type descriptor. This is used to provide the cache with detailed type information of the key and value objects. Example usage with Cache2kBuilder:

   

   CacheBuilder.newCache().valueType(new CacheType<List<String>(){}).build()
 

This constructs a cache with the known type List<String> for its value.
