Detailed Description

template<typename ValueT>
class vlink::SecurityGetter< ValueT >

Convenience alias of Getter with per-message decryption enabled.

Equivalent to Getter<ValueT, SecurityType::kWithSecurity>. Each incoming payload is decrypted before codec dispatch and caching.

Template Parameters

ValueT Value type to read.

◆ SecurityGetter() [1/2]

template<typename ValueT >

template<typename ConfT , typename SecurityConfigT , typename >

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

inlineexplicit

Constructs a SecurityGetter from a typed configuration object.

Template Parameters

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

Parameters

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

Here is the call graph for this function:

◆ SecurityGetter() [2/2]

template<typename ValueT >

template<typename SecurityConfigT >

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

inlineexplicit

Constructs a SecurityGetter from a URL string and installs the security configuration.

Builds the base Getter in kWithoutInit mode, installs sec_cfg via enable_security(), then calls init() unless deferred. When enable_security() fails to produce a usable NodeImpl::security the subsequent init() will fail.

Template Parameters

SecurityConfigT Forwardable Security::Config compatible type.

Parameters

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

Parameters

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

Returns: Owning UniquePtr to the new secure getter.
