Public Member Functions
	TSdlNestedField (InnerType OuterType::innerObjPtr, const TSdlOwnedField< InnerType > innerObjField)

void	ownedValueToDefault (OuterType &outerObj) const override
	Set the value of the field to a default one. Since the field class is templatized by `Owner` type, we are able to define default value on a per owner type basis.

std::string	valueToString (const OuterType &outerObj) const override
	Convert the value of the field to human-readable string.

void	ownedResources (const OuterType &outerObj, std::vector< const ISdlResource * > &out_resources) const override
	Get all SDL resources associated by `owner`.

SdlNativeData	ownedNativeData (OuterType &outerObj) const override
	Direct access to the field memory of an owner. Short-lived owner objects such as function parameter structs must be kept alive during during this call and any further usages of the returned native data.

	TSdlOwnedField (std::string typeName, std::string valueName, std::string typeSignature)

SdlNativeData	nativeData (SdlNonConstInstance instance) const override
	Direct access to the field memory of a SDL instance. Note that this field may not necessarily be bound to a SDL resource type (e.g., may bound to any function parameter structs). Empty native data info will be returned in cases where this field is not owned by (or being part of) the input instance. Obtaining native data requires the input instance be valid during this call and any further usages of the returned native data.

void	fromSdl (OuterType &owner, const SdlInputClause &clause, const SdlInputContext &ctx) const
	Acquire value and store in the owner's field. The loading process will follow a series of preset policy. In addition, failed loading attempt may be recovered if needed.

bool	isFallbackEnabled () const
	Whether the field want to use built-in mechanism to handle I/O problems. An example of this is default field value. With fallback enabled, the field may set itself to the default value supplied (if available) on error. By default, fallback is enabled.

Protected Member Functions
void	loadFromSdl (OuterType &outerObj, const SdlInputClause &clause, const SdlInputContext &ctx) const override
	Load SDL value to actual value and store it in the owner's field. Implementations are highly encouraged to throw SdlLoadError if the loading process is not successful. This will allow things such as automatic fallback to work according to field policies.

void	saveToSdl (const OuterType &outerObj, SdlOutputClause &out_clause, const SdlOutputContext &ctx) const override
	Convert actual value back to SDL value. Saving a loaded value as SDL value should rarely fail–as loaded value has been properly handled by the loading process already. In case of failure, throw SdlSaveError and provide detailed reason describing the event.

SdlField &	setImportance (EFieldImportance importance)
	Sets the importance of the field. Different importance affect the underlying policy used during the import and export of the field, e.g., whether warnings are emitted.

Detailed Description

template<typename OuterType, typename InnerType>
class ph::TSdlNestedField< OuterType, InnerType >

A field that lives within an inner object.

Field properties (importance, fall back, etc.) are initialized to the same values as inner field, and can be overridden by manually setting the properties later.

◆ loadFromSdl()

template<typename OuterType , typename InnerType >

void ph::TSdlNestedField< OuterType, InnerType >::loadFromSdl	(	OuterType &	owner,
		const SdlInputClause &	clause,
		const SdlInputContext &	ctx ) const

inlineoverrideprotectedvirtual

Load SDL value to actual value and store it in the owner's field. Implementations are highly encouraged to throw SdlLoadError if the loading process is not successful. This will allow things such as automatic fallback to work according to field policies.

Parameters

owner	Instance that owns the field.
clause	The SDL representation to be loaded into actual value.
ctx	The context for loading.

Implements ph::TSdlOwnedField< OuterType >.

◆ ownedNativeData()

template<typename OuterType , typename InnerType >

SdlNativeData ph::TSdlNestedField< OuterType, InnerType >::ownedNativeData ( OuterType & owner ) const

inlineoverridevirtual

Direct access to the field memory of an owner. Short-lived owner objects such as function parameter structs must be kept alive during during this call and any further usages of the returned native data.

Implements ph::TSdlOwnedField< OuterType >.

◆ ownedResources()

template<typename OuterType , typename InnerType >

void ph::TSdlNestedField< OuterType, InnerType >::ownedResources	(	const OuterType &	owner,
		std::vector< const ISdlResource * > &	out_resources ) const

inlineoverridevirtual

Get all SDL resources associated by owner.

Parameters

owner	Owner instance in question.
out_resources	SDL resources associated with this field by the owner. Never contains null. Appends to existing ones.

Implements ph::TSdlOwnedField< OuterType >.

◆ ownedValueToDefault()

template<typename OuterType , typename InnerType >

void ph::TSdlNestedField< OuterType, InnerType >::ownedValueToDefault ( OuterType & owner ) const

inlineoverridevirtual

Set the value of the field to a default one. Since the field class is templatized by Owner type, we are able to define default value on a per owner type basis.

Implements ph::TSdlOwnedField< OuterType >.

◆ saveToSdl()

template<typename OuterType , typename InnerType >

void ph::TSdlNestedField< OuterType, InnerType >::saveToSdl	(	const OuterType &	owner,
		SdlOutputClause &	out_clause,
		const SdlOutputContext &	ctx ) const

overrideprotectedvirtual

Convert actual value back to SDL value. Saving a loaded value as SDL value should rarely fail–as loaded value has been properly handled by the loading process already. In case of failure, throw SdlSaveError and provide detailed reason describing the event.

Parameters

owner	Instance that owns the field.
out_clause	The SDL representation for the actual value.
ctx	The context for saving.

Implements ph::TSdlOwnedField< OuterType >.

◆ valueToString()

template<typename OuterType , typename InnerType >

std::string ph::TSdlNestedField< OuterType, InnerType >::valueToString ( const OuterType & owner ) const

inlineoverridevirtual

Convert the value of the field to human-readable string.

Implements ph::TSdlOwnedField< OuterType >.
