FPropertyBagArrayRef

A reference to an array in [FInstancedPropertyBag](API\Runtime\CoreUObject\StructUtils\FInstancedPropertyBag) Allows to modify the array via the [FScriptArrayHelper](API\Runtime\CoreUObject\UObject\FScriptArrayHelper) API, and contains helper methods to get and set properties.

Syntax

class FPropertyBagArrayRef : public FScriptArrayHelper

Remarks

A reference to an array in FInstancedPropertyBag Allows to modify the array via the FScriptArrayHelper API, and contains helper methods to get and set properties. FInstancedPropertyBag Bag; Bag.AddProperties({ { ArrayName, EPropertyBagContainerType::Array, EPropertyBagPropertyType::Float } });

if (auto FloatArrayRes = Bag.GetArrayRef(ArrayName); FloatArrayRes.IsValid()) { FPropertyBagArrayRef& FloatArray = FloatArrayRes.GetValue(); const int32 NewIndex = FloatArray.AddValue(); FloatArray.SetValueFloat(NewIndex, 123.0f); }

Note: The array reference is not valid after the layout of the referenced property bag has changed!
