[protobuf] How to access elements in deeply Nested messages

[greg . brownell]

In the proto file below, how do I access TEST.UUX12.STR21.GFRTE.next ?  I'm 
using c++.  I'm converting some very nasty c structures with nested unions 
and structs. (the example below is just an example).

Thanks,
Greg.

package test_struct;

message GFRTE {
    required int32 next = 1;
}

message gfrte {
    required int32 next1 = 1;
    required int32 prev = 2;
    required GFRTE g_next = 3;
}

message STR2 {
    required uint32 q = 1;
    required bool a1 = 2;
}

message STR3 {
    required int32 h_dim1 = 1 [default = 24];
    required int32 h_dim2 = 2 [default = 5];
    repeated string h = 3;
    required float n = 4;
}

message STR21 {
    required GFRTE q1 = 1;
    required bool a = 2;
    required int32 x54_dim1 = 3 [default = 2];
    repeated int32 x54 = 4;
}

message STR31 {
    required int32 h1_dim1 = 1 [default = 12];
    repeated gfrte h1 = 2;
    required float n1 = 3;
}

message STR41 {
    required int32 h2_dim1 = 1 [default = 100];
    repeated int32 h2 = 2;
    required int32 h3_dim1 = 3 [default = 10];
    required int32 h3_dim2 = 4 [default = 5];
    repeated int32 h3 = 5;
    required float n2 = 6;
}

message STR51 {
    required int32 but = 1;
    optional STR511 str511_1 = 2;
    optional STR522 str522_1 = 3;
}

message STR511 {
    required int32 bq_dim1 = 1 [default = 5];
    repeated gfrte bq = 2;
    required int32 cq = 3;
}

message STR522 {
    required float fq = 1;
    required double lq = 2;
}

message UUX1 {
    required double www = 1;
    optional STR2 str2_1 = 2;
    optional STR3 str3_1 = 3;
}

message UUX12 {
    optional STR21 str21_1 = 1;
    optional STR31 str31_1 = 2;
    optional STR41 str41_1 = 3;
    optional STR51 str51_1 = 4;
}

message UUX51 {
    required double dbl = 1;
    optional STR511 str511_1 = 2;
    optional STR522 str522_1 = 3;
}

message TEST {
    required int32 bb_dim1 = 1 [default = 3];
    repeated int32 bb = 2;
    optional UUX1 uux1_1 = 3;
    optional UUX12 uux12_1 = 4;
}
