well_known_string_indices

protected final java.util.HashMap<java.lang.String,java.lang.Integer> well_known_string_indices

Maps a well-known string to its index in this.well_known_strings.

Fulfills contract that str.equals(well_known_strings.get(well_known_string_indices.get(str))).

well_known_strings

protected final java.util.ArrayList<java.lang.String> well_known_strings

Stores well-known strings (see BinaryFormatConverter(List, List)).

Fulfills contract that str.equals(well_known_strings.get(well_known_string_indices.get(str))).

Constructor Detail

BinaryFormatConverter

public BinaryFormatConverter()

BinaryFormatConverter

public BinaryFormatConverter(java.util.List<java.lang.String> well_known_strings,
                             java.util.List<java.lang.Class<?>> well_known_classes)

Instantiates the converter with lists of strings and classes well-known by both serializer and deserializer.

These strings and class names won't appear in the serialization result (making it shorter by omitting strings from the byte array result of serialization). For serialization and deserialization, the lists passed here must be equal (in particular, the order of elements is important).

Method Detail

serialize

public byte[] serialize(Representation r)

Description copied from class: Converter

Serializes the given representation to the type supported by this converter.

Specified by:

serialize in class Converter<byte[]>

Parameters:

r - the representation to serialize

Returns:

the serialized object

deserialize

public Representation deserialize(byte[] data)

Description copied from class: Converter

Deserializes the given object to its representation.

Specified by:

deserialize in class Converter<byte[]>

Parameters:

data - the object to deserialize

Returns:

the result of deserialization
