build()

std::optional< MeshAccess > MayaFlux::Kakshya::MeshInsertion::build

(

)

const

Produce a MeshAccess over the current variant contents.

Returns std::nullopt if no data has been inserted or if either variant holds the wrong type (indicates a programming error, logged as error). The returned MeshAccess borrows from the two DataVariant references held by this object; both must remain alive while the MeshAccess is in use.
