Enumeration Type Documentation

◆ EPointerPropertyMode

enum EPointerPropertyMode : uint8_t

strong

The deserializer can operate in two modes: using only raw pointers or without any raw pointers at all. The main distinction between the two modes lie in hotloading: in the normal flow of operation, all objects are managed by ResourceManager and internally by ObjectPtrManager. These classes enable the hotloading of objects and they do so by patching internal pointers in non-raw pointers like ObjectPtr, ResourcePtr, ComponentPtr. In such situations, raw pointers are not allowed. However, ObjectPtr and alike are not thread-safe and they should only be used from the main thread. In cases where objects are deserialized directly without the use of ResourceManager, you can use raw pointers instead of ObjectPtr and alike. By enabling OnlyRawPointers or NoRawPointers, the deserializer verifies the correct use of all pointers throughout deserialization.

Enumerator
NoRawPointers	Raw pointers cannot be used to point to other object, only ObjectPtr, ResourcePtr or ComponentPtr, otherwise an error will be returned.
OnlyRawPointers	Only raw pointers can be used to point to other objects, an error will be returned in case of other pointer types.
AllPointerTypes	All types of pointers are supported; no checking is done on raw or non-raw.

◆ EPropertyFileType

strong

Enumerator
Any	Can point to any file, default.
Image	Points to an image file, must be used with EPropertyMetaData::FileLink.

ImageSequence	Points to a an image sequence, must be used with EPropertyMetaData::FileLink.
Audio	Points to an audio file, must be used with EPropertyMetaData::FileLink.
Font	Points to a true type font, must be used with EPropertyMetaData::FileLink.

Required	Load will fail if the property isn't set.
FileLink	Defines a relationship with an external file.
Embedded	An embedded pointer.
ReadOnly	A read only property in Python.

◆ EPropertyValidationMode

enum EPropertyValidationMode : uint8_t

strong

Enumerator
DisallowMissingProperties	When a required property is missing from the file, an error will be returned.
AllowMissingProperties	When a required property is missing from the file, no errors will be returned.

◆ ETypeCheck

enum ETypeCheck : uint8_t

strong

Selects whether the type check should be an exact type match or whether the type should be derived from the given type.

Enumerator
EXACT_MATCH	The type needs to be of the exact same kind.
IS_DERIVED_FROM	The type is derived from the specified type.
