Regarding Handling Repeated Fields in schema

[Yogesh Fulsunge]

Dear Team,

I have a schema which handles repeated fields as shown below, i am facing problems for Initialising the repeated fields.

In my schema, i have one Rack inside that i have multiple Shelf and inside one shelf i have multiple Cards and Slots.

how to handle this kind of scenario in C++ APIs?  

I generated the C++ code and for handling repeated fields it makes use of google::protobuf::RepeatedPtrField  which i am not able to Initialise in code.

can you help me with some sample C++ code to understand the usage? whether i am using correct approach?? please let me know.

is there a way i can generate JSON data structure instead of Templates i guess it will be easier can you please help me in this??

message RackRequest {

required ReqType req_type = 1;

required float rheight = 2;

required float rwidth = 3;

repeated Shelf shelf_in = 4;

enum ReqType {

SEARCH = 0;

ADD = 1;

MODIFY = 2;

DELETE = 3;

}

}

message RackResponse {

required RespType resp_type = 1;

required float rheight = 2;

required float rwidth = 3;

repeated Shelf shelf_in = 4;

enum RespType {

SEARCH = 0;

ADD = 1;

MODIFY = 2;

DELETE = 3;

}

required int32 result_code = 7;

}

message Shelf {

    required float sxaxis = 1;

    required float syaxis = 2;

    required float sheight = 3;

    required float swidth = 4;

    required bool sconfigurable = 5;

repeated Card card_in = 6;

repeated Slot slot_in = 7;

}

message Card {

    required float cxaxis = 1;

    required float cyaxis = 2;

    required float cheight = 3;

    required float cwidth = 4;

    required bool cconfigurable = 5;

    repeated int32 port = 6;

    }

message Slot {

    required float cxaxis = 1;

    required float cyaxis = 2;

    required float cheight = 3;

    required float cwidth = 4;

    required bool cconfigurable = 5;

    repeated int32 port = 6;

    }

Please refer to the generated code guide for repeated message fields:

https://developers.google.com/protocol-buffers/docs/reference/cpp-generated#repeatedmessage

You can convert protos to JSON using this utility:

Dear Feng,

I have seen the links, but i am not able to understand how to use them thats why i am asking again.

can you please send me some sample examples for inserting and extracting of a repeated field from its parent message class object?

Regards,

Yogesh
