I have some kind of requirement that I did not find answer from the
document. May someone help me.
I have different message objects which are inherited from one parent.
I need to serialize the objects into one file.
Some kind of solutions like:
e.g.
message Style {
optional int32 color = 3;
optional int32 size = 4;
}
message Text {
optional Style style = 3;
optional string context = 4;
}
message Image {
optional Style style = 3;
optional int32 width = 4;
optional int32 height = 5;
optional bytes data = 6;
}
My Group object includes Text objects and Image objects. But the
position is not fixed.
e.g. Text.Image.Image...Text
and could be: Image.Text...Image...Text
Now I need to serialize the objects into one file, and seek for the
solution using protocol buffer.
Implement this in Java is quite easy, because I can use
DataInputStream and serialize the objects.
Thanks for any hints.
