get_value_impl()

void MayaFlux::Kakshya::PlotContainer::get_value_impl ( const std::vector< uint64_t > &  coords, void *  out, const std::type_info &  type  ) const

overrideprotectedvirtual

Type-erased single-element read.

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

Implements MayaFlux::Kakshya::NDDataContainer.
