public class NTriple
extends CharMarshaller

A pairing of a NTripleSerializer and NTripleParser into a single class with convenience to/of methods.

The general idea is to combine a single serializer and parser inside a simplified API for serializing and parsing POJOs.

Examples:

// Using instance. NTriple nTriple = new NTriple(); MyPojo myPojo = nTriple.read(string, MyPojo.class); String string = nTriple.write(myPojo);

// Using DEFAULT instance. MyPojo myPojo = NTriple.DEFAULT.read(string, MyPojo.class); String string = NTriple.DEFAULT.write(myPojo);

Example output (bean with name/age):

<...> <.../name> "Alice" . <...> <.../age> "30"^^<http://www.w3.org/2001/XMLSchema#int> .

Complex (nested address + array):

<...> <.../name> "Alice" . <...> <.../age> "30"^^... . <...> <.../address> <.../address> . <.../address> <.../street> "123 Main St" . <.../address> <.../city> "Boston" . <.../address> <.../state> "MA" .

// Using static shortcuts. MyPojo myPojo = NTriple.to(string, MyPojo.class); String string = NTriple.of(myPojo);

Default reusable instance.

Constructor Details

NTriple

public NTriple()

Constructor.

Uses NTripleSerializer.DEFAULT and NTripleParser.DEFAULT.

NTriple

public NTriple(NTripleSerializer s,
 NTripleParser p)

Constructor.

Parameters:

s - The serializer to use for serializing output.
Must not be null.

p - The parser to use for parsing input.
Must not be null.

Method Details

of

public static String of(Object object)
                 throws SerializeException

Serializes a POJO to a String 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(String 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(String 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.
