public class Hocon
extends CharMarshaller

A pairing of a HoconSerializer and HoconParser into a single class with convenience to/of methods.

Examples:

// Instance usage Hocon hocon = new Hocon(); MyBean bean = hocon.read(hoconString, MyBean.class); String hoconOut = hocon.write(bean);

// Static DEFAULT instance MyBean bean = Hocon.DEFAULT.read(hoconString, MyBean.class); String hoconOut = Hocon.DEFAULT.write(bean);

Example output (bean):

name = myapp port = 8080 debug = true

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

Field Details

DEFAULT

public static final Hocon DEFAULT

Default reusable instance.

Constructor Details

Hocon

public Hocon()

Constructor.

Uses HoconSerializer.DEFAULT and HoconParser.DEFAULT.

Hocon

public Hocon(HoconSerializer s,
 HoconParser p)

Constructor.

Parameters:

s - The serializer to use.

p - The parser to use.

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.

to

public static <T> T to(Reader input,
 Class<T> type)
                throws ParseException

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

A shortcut for calling DEFAULT.read(input, type) that catches any IOException from the underlying stream and rethrows it as an unchecked ParseException, so the caller is not burdened with a checked exception.

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

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

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

A shortcut for calling DEFAULT.read(input, type, args) that catches any IOException from the underlying stream and rethrows it as an unchecked ParseException, so the caller is not burdened with a checked exception.

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.

A shortcut for calling DEFAULT.write(object, output) that catches any IOException from the underlying stream and rethrows it as an unchecked SerializeException, so the caller is not burdened with a checked exception.

Parameters:

object - The object to serialize.

output - The writer to serialize to.

Throws:

SerializeException - If a problem occurred trying to convert the output or an I/O error occurred on the underlying stream.

toRecords

public static RecordReader toRecords(Object input)
                              throws IOException

Opens a low-level RecordReader cursor over the specified input using the DEFAULT marshaller.

A shortcut for calling DEFAULT.readRecords(input).

Parameters:

input - The input.

Returns:

A new RecordReader.

Throws:

IOException - If a problem occurred opening the underlying input.

ofRecords

public static RecordWriter ofRecords(Object output)
                              throws IOException

Opens a low-level RecordWriter cursor over the specified output using the DEFAULT marshaller.

A shortcut for calling DEFAULT.writeRecords(output).

Parameters:

output - The output.

Returns:

A new RecordWriter.

Throws:

IOException - If a problem occurred opening the underlying output.
