详细描述

Abstract base class for VLink transport configuration objects.

Each supported transport backend has a corresponding Conf subclass that implements the virtual factory methods (create_publisher, create_server, etc.) to produce transport-specific NodeImpl instances. The base class provides default implementations that return nullptr / false, so subclasses only need to override the methods they support.

Conf objects are held exclusively by Url and the six Node<> template classes; they are not intended for direct use by application code.

注解

The parse() method caches the ImplType so that subsequent factory calls know which node role is being requested.

成员类型定义说明

PropertiesMap

using vlink::Conf::PropertiesMap = std::map<std::string, std::string>

Key/value property map type.

Used by transport conf subclasses and NodeImpl to store DDS QoS strings, IP addresses, buffer sizes, and other per-channel tuning parameters (e.g. "dds.ip" = "127.0.0.1").

构造及析构函数说明

~Conf()

virtual vlink::Conf::~Conf ( )

virtual

Virtual destructor.

Conf()

vlink::Conf::Conf ( )

protected

成员函数说明

create_client()

virtual std::unique_ptr< class ClientImpl > vlink::Conf::create_client ( ) const

nodiscardprotectedvirtual

create_getter()

virtual std::unique_ptr< class GetterImpl > vlink::Conf::create_getter ( ) const

nodiscardprotectedvirtual

create_publisher()

virtual std::unique_ptr< class PublisherImpl > vlink::Conf::create_publisher ( ) const

nodiscardprotectedvirtual

create_server()

virtual std::unique_ptr< class ServerImpl > vlink::Conf::create_server ( ) const

nodiscardprotectedvirtual

create_setter()

virtual std::unique_ptr< class SetterImpl > vlink::Conf::create_setter ( ) const

nodiscardprotectedvirtual

create_subscriber()

virtual std::unique_ptr< class SubscriberImpl > vlink::Conf::create_subscriber ( ) const

nodiscardprotectedvirtual

get_impl_type()

virtual ImplType vlink::Conf::get_impl_type ( ) const

nodiscardvirtual

Returns the most recently parsed ImplType.

返回

ImplType cached by the last call to parse(); kUnknownImplType before parse() is called.

被 vlink::Url 重载.

get_transport_type()

virtual TransportType vlink::Conf::get_transport_type ( ) const

nodiscardvirtual

Returns the transport backend this configuration represents.

The base implementation returns TransportType::kUnknown. Each subclass overrides this to return its own TransportType value.

返回

TransportType identifier for this conf.

被 vlink::Url 重载.

is_valid()

virtual bool vlink::Conf::is_valid ( ) const

nodiscardvirtual

Returns true when the configuration holds valid, usable data.

The base implementation always returns false. Subclasses override this to perform transport-specific validation.

返回

true if the configuration is ready to create NodeImpl objects.

被 vlink::Url 重载.

parse()

virtual bool vlink::Conf::parse ( ImplType impl_type ) const

nodiscardvirtual

Validates the conf for the given node role and caches the type.

Called by the Node<> template before invoking any create_*() factory. The base implementation logs a fatal message and returns false for kUnknownImplType; otherwise it caches impl_type and returns true. Concrete subclasses typically call this base and then validate their own fields.

参数

impl_type

The role being requested (e.g. kPublisher).

返回

true on success; false if the type is unknown.

被 vlink::Url 重载.
