详细描述

Runtime-state serialization for state hot reload.

A module that owns mutable runtime state (animation state machines, dialogue sessions, RPG casting, card phases) implements this and registers with eve::cap::addListener<IStateProvider>(). A reload session captures every provider before code/asset reload and restores the captured state afterwards, so running state survives definition changes instead of being reset.

Modules that do not register a provider are treated as stateless and are simply skipped — the same trimming story as IAssetReloader.

构造及析构函数说明

◆ ~IStateProvider()

virtual eve::caps::IStateProvider::~IStateProvider ( )
virtualdefault

成员函数说明

◆ captureState()

virtual bool eve::caps::IStateProvider::captureState ( StateValue &  out)
pure virtual

Serialize current runtime state into out.

◆ resetToDefaults()

virtual bool eve::caps::IStateProvider::resetToDefaults ( )
pure virtual

Reset this provider to its default state (restore fallback).

◆ restoreState()

virtual bool eve::caps::IStateProvider::restoreState ( const StateValue &  in,
std::string *  err = nullptr 
)
pure virtual

Restore captured state onto the (possibly new) definitions.

返回
false when the captured state is incompatible with the new definitions; the reload session then falls back to resetToDefaults().

◆ stateKind()

virtual const char * eve::caps::IStateProvider::stateKind ( ) const
pure virtual

Stable kind label, e.g. "dialogue" / "anim" / "rpg.casting".

类成员变量说明

◆ capabilityName

constexpr const char* eve::caps::IStateProvider::capabilityName = "IStateProvider"
