/**
* This {@link com.hazelcast.cache.ICache} interface is the {@link javax.cache.Cache} extension offered by
* Hazelcast JCache.
* In addition to the standard set of JCache methods defined in the JSR 107 specification, Hazelcast provides
* additional operations to support a broader range of programing styles.
*
* There are three different types of extensions methods provided:
*
* - asynchronous version of typical blocking cache operations (due to remote calls),
* - typical cache operations, providing a custom {@link javax.cache.expiry.ExpiryPolicy} parameter
* to apply a special expiration to that specific operation, and
* - common collection-like operations (e.g. {@link #size()}) or typical Hazelcast-list additions
* (e.g. {@link #destroy()}).
*
*
* To take advantage of the methods of this interface, the {@link javax.cache.Cache} instance needs to be
* unwrapped as defined in the JSR 107 standard ({@link javax.cache.Cache#unwrap(Class)}) by providing the
* {@link com.hazelcast.cache.ICache} interface parameter.
*
* ICache<Key , Value> unwrappedCache = cache.unwrap( ICache.class );
*
* The unwrapped cache instance can now be used for both ICache and Cache operations.
*
* Asynchronous operations:
* For most of the typical operations, Hazelcast provides asynchronous versions to program in a more reactive
* styled way. All asynchronous operations follow the same naming pattern: the operation's name from JCache
* extended by the term Async; for example, the asynchronous version of {@link javax.cache.Cache#get(Object)}
* is {@link #getAsync(Object)}.
* These methods return an {@link com.hazelcast.core.ICompletableFuture} that can be used to get the result by
* either implementing a callback based on {@link com.hazelcast.core.ExecutionCallback}, or waiting for the operation to be
* completed in a blocking fashion {@link java.util.concurrent.Future#get()} or
* {@link java.util.concurrent.Future#get(long, java.util.concurrent.TimeUnit)}.
* In a reactive way:
*
* ICompletableFuture<Value> future = unwrappedCache.getAsync( "key-1" ) ;
* future.andThen( new ExecutionCallback() {
* public void onResponse( Value value ) {
* System.out.println( value );
* }
*
* public void onFailure( Throwable throwable ) {
* throwable.printStackTrace();
* }
* } );
*
* Or in a blocking way:
*
* ICompletableFuture<Value> future = unwrappedCache.getAsync( "key-1" ) ;
* Value value = future.get();
* System.out.println( value );
*
*
* Custom ExpirePolicy:
* For most of the typical operations, Hazelcast provides overloaded versions with an additional
* {@link javax.cache.expiry.ExpiryPolicy} parameter to configure a different expiration policy from the
* default one set in the {@link javax.cache.configuration.CompleteConfiguration} passed to the cache
* creation. Therefore the {@link javax.cache.Cache#put(Object, Object)} operation has an overload
* {@link com.hazelcast.cache.ICache#put(Object, Object, javax.cache.expiry.ExpiryPolicy)} to pass in the
* special policy.
* Important: The overloads use an instance of {@link javax.cache.expiry.ExpiryPolicy}, not
* a {@link javax.cache.configuration.Factory} instance as is used in the configuration.
*
* unwrappedCache.put( "key", "value", new AccessedExpiryPolicy( Duration.ONE_DAY ) );
*
*
* @param the type of key.
* @param the type of value.
