Package org.apache.juneau.marshaller

Class Uon

java.lang.Object

org.apache.juneau.marshaller.Marshaller

org.apache.juneau.marshaller.CharMarshaller

org.apache.juneau.marshaller.Uon

public class Uon
extends CharMarshaller

A pairing of a UonSerializer and UonParser into a single class with convenience read/write methods.

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

Examples:

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

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

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(Object input,
 Class<T> type)
                throws ParseException,
IOException

Parses a UON input object to the specified Java type.

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

Type Parameters:

T - The class type of the object being created.

Parameters:

input - The input.
Can be any of the following types:

• null
• Reader

• byte[] containing UTF-8 encoded text (or charset defined by ReaderParser.Builder.streamCharset(Charset) property value).
• File containing system encoded text (or charset defined by ReaderParser.Builder.fileCharset(Charset) property value).

type - The object type to create.

Returns:

The parsed object.

Throws:

ParseException - Malformed input encountered.

IOException - Thrown by underlying stream.

to

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

Parses a UON input string to the specified Java type.

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.
Can be any of the following: ClassMeta, Class, ParameterizedType, GenericArrayType

args - The type arguments of the class if it's a collection or map.
Can be any of the following: ClassMeta, Class, ParameterizedType, GenericArrayType
Ignored if the main type is not a map or collection.

Returns:

The parsed object.

Throws:

ParseException - Malformed input encountered.
