Detailed Description

Type-erased visitor over a behavior's reflected authoring fields.

ReflectedBehavior::visitFields dispatches each field: leaves to a field() overload (the one closed set; add an overload for a new type), VKM_ENUM_NAMES enums to enumField(), AssetRef<Asset> to assetField(), and VKM_REFLECT-ed structs through beginStruct()/endStruct().

Member Function Documentation

virtual void Vkm::Engine::BehaviorFieldVisitor::enumField	(	const char *	name,
		int &	index,
		const char const	names,
		std::size_t	count )

pure virtual

Visit an enum field, type-erased to (name index, name table).

Serialize by name (names[index]), never the integer, so reordering values keeps scenes valid.

Parameters

name	Field name.
index	In: current value. Out: the visitor's chosen value.
names	Value-ordered names[count] from the enum's EnumNames.
count	Number of names.

virtual void Vkm::Engine::BehaviorFieldVisitor::assetField	(	const char *	name,
		std::string &	assetName,
		AssetType	type )

pure virtual

Visit a field that names an asset, type-erased to (name, kind).

The name, not a handle, is the serializable identity; a serializer needs type to save the asset too, or the reference resolves to nothing on load.

Parameters

name	Field name.
assetName	In: the current reference, empty for none. Out: the visitor's chosen one.
type	Asset kind the field may reference.

virtual bool Vkm::Engine::BehaviorFieldVisitor::beginStruct ( const char * name )

pure virtual

Enter a nested reflected-struct field; return true to descend.

False skips the children and no endStruct() follows, so open per-struct scope (a JSON sub-object, a tree node) only on the true path.

Parameters

name	Field name of the nested struct.
