-/**
- * This interface provides a rich API for working with distributed caches. It includes the following
- * main functionality:
- * <ul>
- * <li>
- *  Various {@code 'get(..)'} methods to synchronously or asynchronously get values from cache.
- *  All {@code 'get(..)'} methods are transactional and will participate in an ongoing transaction
- *  if there is one.
- * </li>
- * <li>
- *  Various {@code 'put(..)'}, {@code 'putIfAbsent(..)'}, and {@code 'replace(..)'} methods to
- *  synchronously or asynchronously put single or multiple entries into cache.
- *  All these methods are transactional and will participate in an ongoing transaction
- *  if there is one.
- * </li>
- * <li>
- *  Various {@code 'remove(..)'} methods to synchronously or asynchronously remove single or multiple keys
- *  from cache. All {@code 'remove(..)'} methods are transactional and will participate in an ongoing transaction
- *  if there is one.
- * </li>
- * <li>
- *  Various {@code 'contains(..)'} method to check if cache contains certain keys or values locally.
- * </li>
- * <li>
- *  Various {@code 'forEach(..)'}, {@code 'forAny(..)'}, and {@code 'reduce(..)'} methods to visit
- *  every local cache entry within this projection.
- * </li>
- * <li>
- *  Various {@code flagsOn(..)'}, {@code 'flagsOff(..)'}, and {@code 'projection(..)'} methods to
- *  set specific flags and filters on a cache projection.
- * </li>
- * <li>
- *  Methods like {@code 'keySet(..)'}, {@code 'values(..)'}, and {@code 'entrySet(..)'} to provide
- *  views on cache keys, values, and entries.
- * </li>
- * <li>
- *  Various {@code 'peek(..)'} methods to peek at values in global or transactional memory, swap
- *  storage, or persistent storage.
- * </li>
- * <li>
- *  Various {@code 'reload(..)'} methods to reload latest values from persistent storage.
- * </li>
- * <li>
- *  Various {@code 'promote(..)'} methods to load specified keys from swap storage into
- *  global cache memory.
- * </li>
- * <li>
- *  Various {@code 'lock(..)'}, {@code 'unlock(..)'}, and {@code 'isLocked(..)'} methods to acquire, release,
- *  and check on distributed locks on a single or multiple keys in cache. All locking methods
- *  are not transactional and will not enlist keys into ongoing transaction, if any.
- * </li>
- * <li>
- *  Various {@code 'clear(..)'} methods to clear elements from cache, and optionally from
- *  swap storage. All {@code 'clear(..)'} methods are not transactional and will not enlist cleared
- *  keys into ongoing transaction, if any.
- * </li>
- * <li>
- *  Various {@code 'evict(..)'} methods to evict elements from cache, and optionally store
- *  them in underlying swap storage for later access. All {@code 'evict(..)'} methods are not
- *  transactional and will not enlist evicted keys into ongoing transaction, if any.
- * </li>
- * <li>
- *  Various {@code 'txStart(..)'} methods to perform various cache
- *  operations within a transaction (see {@link Transaction} for more information).
- * </li>
- * <li>
- *  Various {@code 'gridProjection(..)'} methods which provide {@link org.apache.ignite.cluster.ClusterGroup} only
- *  for nodes on which given keys reside. All {@code 'gridProjection(..)'} methods are not
- *  transactional and will not enlist keys into ongoing transaction.
- * </li>
- * <li>
- * </ul>
- * <h1 class="header">Extended Put And Remove Methods</h1>
- * All methods that end with {@code 'x'} provide the same functionality as their sibling
- * methods that don't end with {@code 'x'}, however instead of returning a previous value they
- * return a {@code boolean} flag indicating whether operation succeeded or not. Returning
- * a previous value may involve a network trip or a persistent store lookup and should be
- * avoided whenever not needed.
- * <h1 class="header">Predicate Filters</h1>
- * All filters passed into methods on this API are checked <b>atomically</b>. In other words the
- * value returned by the methods is guaranteed to be consistent with the filters passed in. Note
- * that filters are optional, and if not passed in, then methods will still work as is without
- * filter validation.
- * <h1 class="header">Transactions</h1>
- * Cache API supports distributed transactions. All {@code 'get(..)'}, {@code 'put(..)'}, {@code 'replace(..)'},
- * and {@code 'remove(..)'} operations are transactional and will participate in an ongoing transaction,
- * if any. Other methods like {@code 'peek(..)'} or various {@code 'contains(..)'} methods may
- * be transaction-aware, i.e. check in-transaction entries first, but will not affect the current
- * state of transaction. See {@link Transaction} documentation for more information
- * about transactions.
- * <h1 class="header">Group Locking</h1>
- * <i>Group Locking</i> is a feature where instead of acquiring individual locks, Ignite will lock
- * multiple keys with one lock to save on locking overhead. There are 2 types of <i>Group Locking</i>:
- * <i>affinity-based</i>, and <i>partitioned-based</i>.
- * <p>
- * With {@code affinity-based-group-locking} the keys are grouped by <i>affinity-key</i>. This means that
- * only keys with identical affinity-key (see {@link AffinityKeyMapped}) can participate in the
- * transaction, and only one lock on the <i>affinity-key</i> will be acquired for the whole transaction.
- * {@code Affinity-group-locked} transactions are started via
- * <code>txStartAffinity(Object, TransactionConcurrency, TransactionIsolation, long, int)</code> method.
- * <p>
- * With {@code partition-based-group-locking} the keys are grouped by partition ID. This means that
- * only keys belonging to identical partition (see {@link Affinity#partition(Object)}) can participate in the
- * transaction, and only one lock on the whole partition will be acquired for the whole transaction.
- * {@code Partition-group-locked} transactions are started via
- * <code>txStartPartition(int, TransactionConcurrency, TransactionIsolation, long, int)</code> method.
- * <p>
- * <i>Group locking</i> should always be used for transactions whenever possible. If your requirements fit either
- * <i>affinity-based</i> or <i>partition-based</i> scenarios outlined above then <i>group-locking</i>
- * can significantly improve performance of your application, often by an order of magnitude.
- * <h1 class="header">Null Keys or Values</h1>
- * Neither {@code null} keys or values are allowed to be stored in cache. If a {@code null} value
- * happens to be in cache (e.g. after invalidation or remove), then cache will treat this case
- * as there is no value at all.
- * <h1 class="header">Peer Class Loading</h1>
- * If peer-class-loading is enabled, all classes passed into cache API will be automatically deployed
- * to any participating grid nodes. However, in case of redeployment, caches will be cleared and
- * all entries will be removed. This behavior is useful during development, but should not be
- * used in production.
- * <h1 class="header">Portable Objects</h1>
- * If an object is defined as portable Ignite cache will automatically store it in portable (i.e. binary)
- * format. User can choose to work either with the portable format or with the deserialized form (assuming
- * that class definitions are present in the classpath). By default, cache works with deserialized form
- * (example shows the case when {@link Integer} is used as a key for a portable object):
- * <pre>
- * InternalCache<Integer, Value> prj = Ignition.grid().cache(null);
- *
- * // Value will be serialized and stored in cache in portable format.
- * prj.put(1, new Value());
- *
- * // Value will be deserialized since it's stored in portable format.
- * Value val = prj.get(1);
- * </pre>
- * You won't be able to work with deserialized form if class definition for the {@code Value} is not on
- * classpath. Even if you have the class definition, you should always avoid full deserialization if it's not
- * needed for performance reasons. To work with portable format directly you should create special projection
- * using {@link #keepPortable()} method:
- * <pre>
- * InternalCache<Integer, GridPortableObject> prj = Ignition.grid().cache(null).keepPortable();
- *
- * // Value is not deserialized and returned in portable format.
- * GridPortableObject po = prj.get(1);
- * </pre>
- * See {@link #keepPortable()} method JavaDoc for more details.

-     * Projection returned by this method will force cache not to deserialize portable objects,
-     * so keys and values will be returned from cache API methods without changes. Therefore,
-     * signature of the projection can contain only following types:
-     * <ul>
-     *     <li><code>org.gridgain.grid.portables.PortableObject</code> for portable classes</li>
-     *     <li>All primitives (byte, int, ...) and there boxed versions (Byte, Integer, ...)</li>

-     *     <li>{@link String} and array of {@link String}s</li>
-     *     <li>{@link UUID} and array of {@link UUID}s</li>
-     *     <li>{@link Date} and array of {@link Date}s</li>
-     *     <li>{@link Timestamp} and array of {@link Timestamp}s</li>
-     *     <li>Enums and array of enums</li>
-     *     <li>
-     *         Maps, collections and array of objects (but objects inside
-     *         them will still be converted if they are portable)
-     *     </li>
-     * </ul>
-     * <p>
-     * For example, if you use {@link Integer} as a key and {@code Value} class as a value
-     * (which will be stored in portable format), you should acquire following projection
-     * to avoid deserialization:
-     * <pre>
-     * InternalCache<Integer, GridPortableObject> prj = cache.keepPortable();
-     *
-     * // Value is not deserialized and returned in portable format.
-     * GridPortableObject po = prj.get(1);
-     * </pre>
-     * <p>
-     * Note that this method makes sense only if cache is working in portable mode
-     * (<code>org.apache.ignite.configuration.CacheConfiguration#isPortableEnabled()</code> returns {@code true}. If not,
-     * this method is no-op and will return current projection.
