set_value_impl()

void MayaFlux::Kakshya::VideoStreamContainer::set_value_impl ( const std::vector< uint64_t > &  coords, const void *  in, const std::type_info &  type  )

overrideprotectedvirtual

Type-erased single-element write.

Implementations copy from in into their storage at coords if type matches their native type, otherwise no-op. in points to a caller-owned buffer of exactly sizeof(native type) bytes.

Implements MayaFlux::Kakshya::NDDataContainer.
