详细描述

template<typename MsgT>
class vlink::SecurityPublisher< MsgT >

Convenience alias for Publisher with message security enabled.

Equivalent to Publisher<MsgT, SecurityType::kWithSecurity>. Encrypts every outgoing message using the key or callbacks configured via set_security_key() or set_security_callbacks().

注解: Not supported on intra:// or dds:// CDR transport.

模板参数

MsgT	Message type to publish.
