Description

The list of methods to do Object Serialize and Deserialize are organized into topic(s).

Method

PropertiesdeserializeProperties(byte[] bytes)
Tries to deserialize given bytes array to Properties instance 
Properties properties = new Properties();
if (bytes != null) {
    try {
        ByteArrayInputStream bais = new ByteArrayInputStream(bytes);
        properties.load(bais);
        bais.close();
    } catch (IOException e) {
return properties;
SerializabledeserializeRaw(byte[] array)
deserialize Raw 
byteInput = new ByteArrayInputStream(array);
objectInput = new ObjectInputStream(byteInput);
Serializable o = (Serializable) objectInput.readObject();
return o;
voiddeserializeSafe(byte[] buf, T obj)
deserialize Safe 
ByteArrayInputStream bis = null;
try {
    bis = new ByteArrayInputStream(buf);
    ObjectInputStream oin = null;
    try {
        oin = new ObjectInputStream(bis);
        obj.readExternal(oin);
    } finally {
...
shortdeserializeShort(byte[] inbuf, int offset)
Deserialize a short, but do not convert it from little endian in the process 
return (short) ((inbuf[offset] & 0xff) << 8 | (inbuf[offset + 1] & 0xff));
ObjectdeserializeStream(final String witness)
Deserializes a specified file. 
FileInputStream fileIs = new FileInputStream(witness);
ObjectInputStream objIs = new ObjectInputStream(fileIs);
return objIs.readObject();
ObjectserializeAndDeserialize(Object o)
Serializes and deserializes the given object. 
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
ObjectOutputStream out = new ObjectOutputStream(bytes);
try {
    out.writeObject(o);
} finally {
    out.close();
ObjectInputStream in = new ObjectInputStream(new ByteArrayInputStream(bytes.toByteArray()));
...
ObjectserializeAndDeserialize(Object o)
serialize And Deserialize 
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ObjectOutputStream oos = new ObjectOutputStream(baos);
oos.writeObject(o);
oos.flush();
baos.flush();
byte[] bytes = baos.toByteArray();
ByteArrayInputStream is = new ByteArrayInputStream(bytes);
ObjectInputStream ois = new ObjectInputStream(is);
...
ObjectserializeAndDeserialize(Object obj)
serialize And Deserialize 
ByteArrayOutputStream bout = new ByteArrayOutputStream();
ObjectOutputStream out = new ObjectOutputStream(bout);
out.writeObject(obj);
out.flush();
ByteArrayInputStream bin = new ByteArrayInputStream(bout.toByteArray());
ObjectInputStream in = new ObjectInputStream(bin);
obj = in.readObject();
return obj;
...
TserializeAndDeserialize(T input)
Serialize and Deserialize an object Useful for testing if serialization is correctly handled for a class. 
final ByteArrayOutputStream byteArrayStream = new ByteArrayOutputStream();
final ObjectOutputStream out = new ObjectOutputStream(byteArrayStream);
out.writeObject(input);
final ObjectInputStream in = new ObjectInputStream(new ByteArrayInputStream(byteArrayStream.toByteArray()));
@SuppressWarnings("unchecked")
final T result = (T) in.readObject();
out.close();
in.close();
...
TserializeAndDeserialize(T instance)
serialize And Deserialize 
return (T) deserialize(serialize(instance));
