Most efficient way to copy a DDS String sequence to std::vector<std::string> and back

I am wondering what is the most efficient (but safe) way to copy a DDS String sequence (using the 'old' DDS C++ API) to a std::vector<std::string> and back? In how far can C++11 move semantics be used safely?

Send String Arrays using Dynamic Data and Request-Reply pattern

Hello,

I am a bit new to DDS. I am curently working with the request/reply pattern. I successfully managed to send requests and replies containing primitive types of data such as char, long, int, etc. What I am not trying to do is sending some string array with the request reply pattern and using Dynamic Data as the string array I'm trying to send must be custom made. Until now I managed to do something like this:

 

//Register the type support for creating string arrays

DDS_TypeCode* type = factory->create_struct_tc("MyType", structMembers, out_exc);

Sequence - SIGABRT invalid pointer (C++)

Hi,

I'm struggling with an embedded sequence within a struct. When I try to send it, the application terminates with a SIGABRT.

Given the following IDL:

-------------------------snip-----------------------------
const long MAX_STRING_LENGTH = 256;

enum StudentStatus{
ENROLLED,
ALUMNI
};

struct Student{
string<MAX_STRING_LENGTH> name;
string<MAX_STRING_LENGTH> familyname;
StudentStatus status;
};

Setting an array of strings

Given next field in a topic.

<member name="exerciseNickname"          type="string" arrayDimensions="4" stringMaxLength="20"/>

With the usual dynamicdata you have set some array types to set as double, byte, float, etc but there's no set_string_array.

Notice in my case i don't use idl file i use a file .qos to describe every topic instead.

How can i set the array of string?
