Library to read and parse Unreal Engine 4 manifest and delta files.
- Read and parse a raw serialized (json format is NOT supported) manifest from a file (.manifest | .delta usually), a byte array, a stream or an Uri.
- Choose whether to write the output in a specific json format or keep it simple. (more details in the library XML documentation)
- Fast execution. Not writing the output to file makes the execution faster.
- Choose how to format the json output (indented or not).
- Choose which fields to read and which to skip. The less fields, the faster the execution.
