	)		const

overridevirtual

Returns true if this property, or in the case of e.g. array or struct properties any sub- property, contains a UObject reference.

Parameters

EncounteredStructProps	used to check for recursion in arrays
InReferenceType	type of object reference (strong / weak)

Returns: true if property (or sub- properties) contains the specified type of UObject reference, false otherwise

Returns true if this property, or in the case of e.g. array or struct properties any sub- property, contains a UObject reference.

Returns: true if property (or sub- properties) contain a UObject reference, false otherwise

Reimplemented from FProperty.

◆ ConvertFromType()

EConvertFromTypeResult FOptionalProperty::ConvertFromType	(	const FPropertyTag &	Tag,
		FStructuredArchive::FSlot	Slot,
		uint8 *	Data,

		const uint8 *	Defaults
	)

overridevirtual

Allows a property to implement backwards compatibility handling for tagged properties

Parameters

Tag	property tag of the loading data
Ar	the archive the data is being loaded from
Data	a pointer to the container to write the loaded data to
DefaultsStruct
Defaults	if available, a pointer to the container containing the default value for this property, or null

Returns: A state which tells the tagged property system how the property dealt with the data. Converted: the function handled conversion. CannotConvert: the tag is not something that the property can convert. Serialized: the function handled serialization without conversion. UseSerializeItem: no conversion was done on the property - this can mean that the tag is correct and normal serialization applies or that the tag is incompatible.

Visits this property and allows recursion into the inner properties This method allows callers to visit inner properties without knowing about its container type as opposed to TPropertyIterator. This visit property pattern facilitates the recursion into user defined properties and allows users to add specific visit logic on UStruct via traits.

Parameters

Context	which containes the path that was computed until we reached this property and the sata to the property to visit
InFunc	to call on each visited property, the return value controls what is the next behavior once this property has been visited

Returns: the new action to take one visited this property
