Module: Mxrb::IO::MxunitCodec

Defined in:
lib/mxrb/io/mxunit_codec.rb

Overview

Storage adapter for MPR v2 unit files.

Mendix currently stores the serialized unit payload outside SQLite. The payload is kept opaque here: known BSON payloads can be decoded, while unknown/newer encodings fail explicitly instead of being overwritten.
