Suppose, there's a 3rd party class:
public class A {
private int v;
public A(int v) {
this.v = v;
}
public int v() {
return v;
}
}
If you want it to deserialize on client, you usually write a
CustomFieldSerializer that calls the constructor in instantiate():
public class A_CustomFieldSerializer extends CustomFieldSerializer<A> {
public static void deserialize(SerializationStreamReader
streamReader,
A instance) throws SerializationException {
}
public static A instantiate(SerializationStreamReader streamReader)
throws SerializationException {
return new A(streamReader.readInt());
}
public static void serialize(SerializationStreamWriter streamWriter,
A instance) throws SerializationException {
streamWriter.writeInt(instance.v());
}
@Override
public void deserializeInstance(SerializationStreamReader
streamReader,
A instance) throws SerializationException {
deserialize(streamReader, instance);
}
@Override
public boolean hasCustomInstantiateInstance() {
return true;
}
@Override
public A instantiateInstance(SerializationStreamReader streamReader)
throws SerializationException {
return instantiate(streamReader);
}
@Override
public void serializeInstance(SerializationStreamWriter
streamWriter,
A instance) throws SerializationException {
serialize(streamWriter, instance);
}
}
If someone tries to extends this class, deserialization corrupts the
stream, because readInt() is not called:
public class B extends A {
public B() {
super(0);
}
}
