详细描述

One state hot-reload transaction: capture → reload → restore.

A script reload (soft_reload_scripts) drives this via the eve.dev API:

begin(): snapshot script state roots + every registered IStateProvider into an in-memory buffer, and persist eve_snapshot.json as a manual rollback point.
(scripts are re-dofile'd in between)
commit(): restore the captured state on top of the new definitions — captured root values win, fields the new script added are kept, native providers are restored (falling back to resetToDefaults() on failure).
abort(): restore the captured state unchanged and clear the session.

构造及析构函数说明

◆ ReloadSession()

eve::dev::ReloadSession::ReloadSession ( const ReloadSession & )

delete

成员函数说明

◆ abort()

bool eve::dev::ReloadSession::abort	(	HSQUIRRELVM	vm,
		std::string *	err = `nullptr`
	)

End the session, rolling back to the captured state.

在文件 ReloadSession.cpp 第 59 行定义.

引用了 eve::StateValue::null(), ok , 以及 vm.

◆ active()

bool eve::dev::ReloadSession::active ( ) const

inline

Whether a session is currently open.

在文件 ReloadSession.h 第 50 行定义.

◆ begin()

bool eve::dev::ReloadSession::begin	(	HSQUIRRELVM	vm,
		std::string *	err = `nullptr`
	)

Start a session: capture current script + native state.

返回: false when capture fails (session stays inactive).

在文件 ReloadSession.cpp 第 12 行定义.

引用了 eve::dev::Snapshot::instance(), eve::StateValue::null(), eve::dev::Snapshot::saveFile() , 以及 vm.

◆ commit()

bool eve::dev::ReloadSession::commit	(	HSQUIRRELVM	vm,
		std::string *	err = `nullptr`
	)

End the session, restoring captured state over the new definitions (old values win; newly added fields kept).

在文件 ReloadSession.cpp 第 28 行定义.

引用了 eve::StateValue::find(), eve::dev::Snapshot::instance(), eve::StateValue::isObject(), eve::StateValue::keys(), eve::StateValue::mergeDefaults(), name, eve::StateValue::null(), ok , 以及 vm.

◆ instance()

ReloadSession & eve::dev::ReloadSession::instance ( )

static

被这些函数引用 eve::dev::DevTool::exposeScriptApi().

◆ operator=()

ReloadSession & eve::dev::ReloadSession::operator= ( const ReloadSession & )
