public class PrototextR
extends Prototext

A Prototext variant that produces readable (whitespace-padded) Protobuf Text Format output.

This is the first-class facade form of the readable Prototext variant. It pairs PrototextSerializer.DEFAULT_READABLE with PrototextParser.DEFAULT and exposes the full static shortcut surface bound to its own DEFAULT instance.

Examples:

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

Notes:

• Because Java hides (does not override) static members, this class redeclares the entire static shortcut surface of Prototext so that every shortcut is bound to this class's readable DEFAULT rather than the Prototext.DEFAULT.

Method Details

of

public static String of(Object object)
                 throws SerializeException

Serializes a POJO to a String using the DEFAULT marshaller.

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.

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.

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.

Parses the contents of a Reader into the specified object type using the DEFAULT marshaller.

Catches any IOException from the underlying stream and rethrows it as an unchecked ParseException.

Type Parameters:

T - The class type of the object being created.

Parameters:

input - The input reader.

type - The object type to create.

Returns:

The parsed object.

Throws:

ParseException - Malformed input encountered or an I/O error occurred on the underlying stream.

to

Type Parameters:

T - The class type of the object to create.

Parameters:

input - The input reader.

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 or an I/O error occurred on the underlying stream.

of

public static void of(Object object,
 Writer output)
               throws SerializeException

Serializes a POJO to the specified Writer using the DEFAULT marshaller.
