Flattening

Flattening is a LabVIEW term for Serialization. Objects in LV are flattened in order to be saved to file or transmitted over network or serial interface, then unflattened in order to be used again.

Saving a VI file on disk can be considered as flattening all the resources from it.

In 2017, a vulnerability was discovered in LV code for unflattening variable of Variant data type.
