详细描述

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

Convenience alias of Publisher with per-message security enabled.

Equivalent to Publisher<MsgT, SecurityType::kWithSecurity>. Every outgoing payload is encrypted with the configured Security::Config before transmission; an empty config falls back to the built-in default symmetric slot.

注解: Security is not supported on intra:// or on dds:// CDR payloads – using a SecurityPublisher in those configurations is a constructor-time fatal.

模板参数

MsgT	C++ message type to publish.

成员类型定义说明

◆ SharedPtr

template<typename MsgT >

using vlink::SecurityPublisher< MsgT >::SharedPtr = std::shared_ptr<SecurityPublisher<MsgT> >

Owning shared-pointer alias.

◆ UniquePtr

template<typename MsgT >

using vlink::SecurityPublisher< MsgT >::UniquePtr = std::unique_ptr<SecurityPublisher<MsgT> >

Owning unique-pointer alias.

构造及析构函数说明

◆ SecurityPublisher() [1/2]

template<typename MsgT >

template<typename ConfT , typename SecurityConfigT , typename >

vlink::SecurityPublisher< MsgT >::SecurityPublisher	(	const ConfT &	conf,
		SecurityConfigT &&	sec_cfg = `{}`,
		InitType	type = `InitType::kWithInit`
	)

inlineexplicit

Constructs a SecurityPublisher from a typed configuration object.

Constructs the base Publisher in kWithoutInit mode, installs sec_cfg via enable_security(), then runs init() unless deferred. If enable_security() fails to populate a usable security object the subsequent init() will fail.

模板参数

ConfT	Configuration type derived from `Conf`.
SecurityConfigT	Forwardable `Security::Config` compatible type.

参数

conf	Populated configuration aggregate.
sec_cfg	Security configuration; empty uses the default symmetric slot.
type	Whether to call `init()` inline; default is `InitType::kWithInit`.

◆ SecurityPublisher() [2/2]

template<typename MsgT >

template<typename SecurityConfigT >

vlink::SecurityPublisher< MsgT >::SecurityPublisher	(	const std::string &	url_str,
		SecurityConfigT &&	sec_cfg = `{}`,
		InitType	type = `InitType::kWithInit`
	)

inlineexplicit

Constructs a SecurityPublisher from a URL string.

模板参数

SecurityConfigT Forwardable Security::Config compatible type.

参数

url_str	Topic URL string.
sec_cfg	Security configuration; empty uses the default symmetric slot.
type	Whether to call `init()` inline; default is `InitType::kWithInit`.

成员函数说明

◆ create_shared()

template<typename MsgT >

template<typename SecurityConfigT >

SecurityPublisher< MsgT >::SharedPtr vlink::SecurityPublisher< MsgT >::create_shared	(	const std::string &	url_str,

		InitType	type = `InitType::kWithInit`
	)

inlinestatic

Heap-allocates a SecurityPublisher and wraps it in a std::shared_ptr.

模板参数

SecurityConfigT Forwardable Security::Config compatible type.

参数

url_str	Topic URL string.
sec_cfg	Security configuration; empty uses the default symmetric slot.
type	Whether to call `init()` inline; default is `InitType::kWithInit`.

返回: Owning SharedPtr to the new secure publisher.

◆ create_unique()

template<typename MsgT >

template<typename SecurityConfigT >

SecurityPublisher< MsgT >::UniquePtr vlink::SecurityPublisher< MsgT >::create_unique	(	const std::string &	url_str,
		SecurityConfigT &&	sec_cfg = `{}`,
		InitType	type = `InitType::kWithInit`
	)

inlinestatic

Heap-allocates a SecurityPublisher and wraps it in a std::unique_ptr.

模板参数

SecurityConfigT Forwardable Security::Config compatible type.

参数

url_str	Topic URL string.
sec_cfg	Security configuration; empty uses the default symmetric slot.
type	Whether to call `init()` inline; default is `InitType::kWithInit`.

返回: Owning UniquePtr to the new secure publisher.
