Class SerializableType

java.lang.Object

pt.unl.fct.di.novasys.babel.crdts.utils.datatypes.SerializableType

All Implemented Interfaces:

Comparable<Object>

Direct Known Subclasses:

BooleanType, ByteArrayType, ByteType, DoubleType, FloatType, IntegerType, LongType, ShortType, StringType

public abstract class SerializableType
extends Object
implements Comparable<Object>

Represents an abstract data type that can be serialized to be sent over the network. The class should be realized by a concrete data type (i.e., Integer, Boolean, etc. or a generic data type implemented by the developer) that is mapped to a data type.

Constructor Detail

SerializableType

public SerializableType(DataTypes dataType)

Creates a SerializableType object and stores is concrete data type.

Parameters:

dataType - a PrimitiveDataType enumerator instance.

Method Detail

getDataType

public DataTypes getDataType()

Gets the data type of the object. This method can be used to infer the concrete data type of the object, which can be used to serialize (and deserialize) the object from the network.

Returns:

the data type

getValue

public abstract Object getValue()

Gets the value stored by the object.

Returns:

the value

serialize

public abstract void serialize(io.netty.buffer.ByteBuf out)
                        throws IOException

Throws:

IOException

copy

public abstract SerializableType copy()

deserializeDataType

public static SerializableType deserializeDataType(DataTypes dataType,
                                                   io.netty.buffer.ByteBuf in)
                                            throws IOException

A static method that deserializes a SerializableType by receiving it's concrete data type as an argument. The concrete serializer of the object is used based on the dataType passed into the method

Parameters:

dataType - data type of the object

in - ByteBuf where the object is stored

Returns:

the serialized object as a SerializableType

Throws:

IOException - if there is an error parsing the object
