详细描述

Pure-virtual interface that every shared-library logger backend implements.

Concrete subclasses use VLINK_PLUGIN_REGISTER internally to expose their factory and destructor functions to the Plugin loader. Instances are owned by the host application for the duration of the plugin handle.

构造及析构函数说明

◆ LoggerPluginInterface()

vlink::LoggerPluginInterface::LoggerPluginInterface ( )

protecteddefault

◆ ~LoggerPluginInterface()

virtual vlink::LoggerPluginInterface::~LoggerPluginInterface ( )

protectedvirtualdefault

成员函数说明

◆ init()

virtual bool vlink::LoggerPluginInterface::init ( std::string_view app_name )

pure virtual

Initialises the backend immediately after the plugin instance is constructed.

参数

app_name Calling application name; may inform log labels or file paths.

返回: true on success; false to indicate the plugin must not be used further.

◆ log()

virtual bool vlink::LoggerPluginInterface::log	(	int	level,
		std::string_view	str
	)

pure virtual

Writes a single record to the backend.

Implementations should be non-blocking; str remains valid only for the duration of the call.
