+/**
+ * Wrapper for portable object in portable binary format. Once an object is 
defined as portable,
+ * Ignite will always store it in memory in the 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).
+ * <p>
+ * <b>NOTE:</b> user does not need to (and should not) implement this 
interface directly.
+ * <p>
+ * To work with the portable format directly, user should create a cache 
projection
+ * over {@code PortableObject} class and then retrieve individual fields as 
needed:
+ * <pre name=code class=java>
+ * IgniteCache&lt;PortableObject, PortableObject&gt; prj = 
cache.withKeepBinary();
+ *
+ * // Convert instance of MyKey to portable format.
+ * // We could also use GridPortableBuilder to create the key in portable 
format directly.
+ * PortableObject key = grid.portables().toPortable(new MyKey());
+ *
+ * PortableObject val = prj.get(key);
+ *
+ * String field = val.field("myFieldName");
+ * </pre>
+ * Alternatively, if we have class definitions in the classpath, we may choose 
to work with deserialized
+ * typed objects at all times. In this case we do incur the deserialization 
cost. However, if
+ * {@link PortableMarshaller#isKeepDeserialized()} is {@code true} then Ignite 
will only deserialize on the first access
+ * and will cache the deserialized object, so it does not have to be 
deserialized again:
+ * <pre name=code class=java>
+ * IgniteCache&lt;MyKey.class, MyValue.class&gt; cache = grid.cache(null);
+ *
+ * MyValue val = cache.get(new MyKey());
+ *
+ * // Normal java getter.
+ * String fieldVal = val.getMyFieldName();
+ * </pre>
+ * <h1 class="header">Working With Maps and Collections</h1>
+ * All maps and collections in the portable objects are serialized 
automatically. When working
+ * with different platforms, e.g. C++ or .NET, Ignite will automatically pick 
the most
+ * adequate collection or map in either language. For example, {@link 
ArrayList} in Java will become
+ * {@code List} in C#, {@link LinkedList} in Java is {@link LinkedList} in C#, 
{@link HashMap}
+ * in Java is {@code Dictionary} in C#, and {@link TreeMap} in Java becomes 
{@code SortedDictionary}
+ * in C#, etc.
+ * <h1 class="header">Dynamic Structure Changes</h1>
+ * Since objects are always cached in the portable binary format, server does 
not need to
+ * be aware of the class definitions. Moreover, if class definitions are not 
present or not
+ * used on the server, then clients can continuously change the structure of 
the portable
+ * objects without having to restart the cluster. For example, if one client 
stores a
+ * certain class with fields A and B, and another client stores the same class 
with
+ * fields B and C, then the server-side portable object will have the fields 
A, B, and C.
+ * As the structure of a portable object changes, the new fields become 
available for SQL queries
+ * automatically.
+ * <h1 class="header">Building Portable Objects</h1>
+ * Ignite comes with {@link IgniteObjectBuilder} which allows to build 
portable objects dynamically:
+ * <pre name=code class=java>
+ * PortableBuilder builder = 
Ignition.ignite().portables().builder("org.project.MyObject");
+ *
+ * builder.setField("fieldA", "A");
+ * builder.setField("fieldB", "B");
+ *
+ * PortableObject portableObj = builder.build();
+ * </pre>
+ * For the cases when class definition is present
+ * in the class path, it is also possible to populate a standard POJO and then
+ * convert it to portable format, like so:
+ * <pre name=code class=java>
+ * MyObject obj = new MyObject();
+ *
+ * obj.setFieldA("A");
+ * obj.setFieldB(123);
+ *
+ * PortableObject portableObj = Ignition.ignite().portables().toPortable(obj);
+ * </pre>
+ * <h1 class="header">Portable Metadata</h1>
+ * Even though Ignite portable protocol only works with hash codes for type 
and field names
+ * to achieve better performance, Ignite provides metadata for all portable 
types which
+ * can be queried ar runtime via any of the {@link 
org.apache.ignite.IgniteObjects#metadata(Class)}
+ * methods. Having metadata also allows for proper formatting of {@code 
PortableObject.toString()} method,
+ * even when portable objects are kept in binary format only, which may be 
necessary for audit reasons.

+/**
+ * Portable object builder. Provides ability to build portable objects 
dynamically without having class definitions.
+ * <p>
+ * Here is an example of how a portable object can be built dynamically:

+ * PortableBuilder builder =

+ *
+ * builder.setField("fieldA", "A");

+ * <p>
+ * Also builder can be initialized by existing portable object. This allows 
changing some fields without affecting
+ * other fields.
+ * <pre name=code class=java>
+ * PortableBuilder builder = Ignition.ignite().portables().builder(person);
+ *
+ * builder.setField("name", "John");
+ *
+ * person = builder.build();
+ * </pre>
+ * </p>
+ *
+ * If you need to modify nested portable object you can get builder for nested 
object using
+ * {@link #getField(String)}, changes made on nested builder will affect

+ *
+ * <pre name=code class=java>

+ * PortableBuilder addressBuilder = personBuilder.setField("address");
