public class RdfProto
extends StreamMarshaller

A pairing of RdfProtoSerializer and RdfProtoParser for RDF/PROTO binary format.

Examples:

// Serialize a bean or map to RDF/PROTO bytes byte[] bytes = RdfProto.of(myBean); // Parse RDF/PROTO bytes into a bean or map MyPojo parsed = RdfProto.to(bytes, MyPojo.class);

// Using instance methods RdfProto m = RdfProto.DEFAULT; bytes = m.write(myBean); parsed = m.read(bytes, MyPojo.class);

Output is binary (byte[]), Protocol Buffers format.

Complex structures (nested objects, arrays) serialize to equivalent RDF triples in binary form.

// Using static shortcuts. MyPojo myPojo = RdfProto.to(bytes, MyPojo.class); byte[] bytes = RdfProto.of(myPojo);

Method Details

of

public static byte[] of(Object object)
                 throws SerializeException

Serializes a POJO to a byte[] using the DEFAULT marshaller.

A shortcut for calling DEFAULT.write(object).

Parameters:

object - The object to serialize.

Returns:

The serialized object.

Throws:

SerializeException - If a problem occurred trying to convert the output.

to

public static <T> T to(byte[] input,
 Class<T> type)
                throws ParseException

Parses an input into the specified object type using the DEFAULT marshaller.

A shortcut for calling DEFAULT.read(input, type).

Type Parameters:

T - The class type of the object being created.

Parameters:

input - The input.

type - The object type to create.

Returns:

The parsed object.

Throws:

ParseException - Malformed input encountered.

to

public static <T> T to(byte[] input,
 Type type,
 Type... args)
                throws ParseException

Parses an input into the specified parameterized object type using the DEFAULT marshaller.

A shortcut for calling DEFAULT.read(input, type, args).

Type Parameters:

T - The class type of the object to create.

Parameters:

input - The input.

type - The object type to create.

args - The type arguments of the class if it's a collection or map.

Returns:

The parsed object.

Throws:

ParseException - Malformed input encountered.
