Nested messages using C++

[Linus]

Hello,

I have nested messages like the following (it is a little more
complicated, but i am trying to simplify with this example).

package DB;

message Header
{
required int32 ID=1;
message param
{
required int32 size_m = 1;
required int32 size_n = 2;
}
required param p = 2;
}

message data
{
repeated double = 1;
}


message DB
{
required Header = 1;
required data = 2;
}


The problem I am having is that the accessor methods generated for the
"DB " does not have a
set_param( DB::Header::param ).

Is there something wrong with how I am structuring my messages? Any
help is appreciated.
Please let me know if this post is unclear and I will try and explain
myself better.

Thanks!
Linus

I am new to PB and I just ran into this. Is it possible that the PB
compiler does not generate set_<...> methods for some nested messages?

Here is an example: I don't see set_<...> methods for ANY of the
parameters in the db message.

What am I missing???

package pd;

message nv
{
repeated int32 Length = 1;
}

message dp
{
required int32 DesignID = 1;
repeated double Design = 2;
}

message Shape

{
required int32 size_m = 1;
required int32 size_n = 2;
}

message ds
{
required int32 DesignID = 1;
repeated double data = 2;
}

message db
{
required nv numVars = 1;
repeated dp despar = 2;
required Shape db_size = 3;
repeated ds dtst = 4;

For message type fields, there is no set_<...> method. The codegen produces mutable_<...> methods instead. Otherwise it is easy to write inefficient code - set would require a potentially expensive copy of the message.

By the way this is documented here: http://code.google.com/apis/protocolbuffers/docs/reference/cpp-generated.html#fields

Cool!
Thank you for the clarification.
