Syntax

class FTransformSource

Remarks

FTransformSource

Defines common API for storing owners of a transform hierarchy. For example, to store the component that generated a transform hierirchy, use the function : Key = this->AddTransformSource(="">, ="">, {="">});

Key = this->AddTransformSource("", GUID, {1,5,7});

The source root indices can be queries later using the name and guid: TSet SourceRoots = this->GetSourceTransformRoots("", GUID);

The following groups are created on the collection based on which API is called.

= FTransformSource::TransformSourceGroup

FindAttribute(FTransformSource::SourceNameAttribute, );
FindAttribute(FTransformSource::SourceGuidAttribute, );
FindAttribute<TSet>(FTransformSource::SourceRootsAttribute, );
