MnaProject

Namespace: MNALIB  ·  Library: MNA Library

#include <mna/mna_project.h>

class MNALIB::MnaProject

Top-level MNA project container.

Holds subjects, pipeline steps, and project metadata.

src/examples/ex_mna/main.cpp
MnaProject project;
project.name = "ex_mna";
project.subjects.append(subject);
project.pipeline = graph.nodes();
const QString jsonPath = dir.filePath("pipeline.mna"); // UTF-8 JSON
const QString cborPath = dir.filePath("pipeline.mnx"); // CBOR with an "MNX1" magic
const bool saved = MnaIO::write(project, jsonPath) && MnaIO::write(project, cborPath);
const MnaProject fromJson = MnaIO::read(jsonPath);
const MnaProject fromCbor = MnaIO::read(cborPath);

Public Methods​

MnaProject()​

Default constructor.

toJson()​

Serialize to QJsonObject.

Returns:

  • QJsonObject — JSON object with all project fields, subjects, pipeline nodes and preserved extras.

toCbor()​

Serialize to QCborMap.

Returns:

  • QCborMap — CBOR map with all project fields, subjects, pipeline nodes and preserved extras.

Static Methods​

fromJson(json)​

Deserialize from QJsonObject.

Parameters:

  • json : const QJsonObject & JSON object as produced by toJson().

Returns:

  • MnaProject — The project; missing keys take default values and unknown keys go to extras.

fromCbor(cbor)​

Deserialize from QCborMap.

Parameters:

  • cbor : const QCborMap & CBOR map as produced by toCbor().

Returns:

  • MnaProject — The project; missing keys take default values and unknown keys go to extras.

read(path)​

Read an MNA project from file.

Delegates to MnaIO.

Parameters:

  • path : const QString & Path to the .mna or .mnx file.

Returns:

write(project, path)​

Write an MNA project to file.

Delegates to MnaIO.

Parameters:

  • project : const MnaProject & The project to write.

  • path : const QString & Path to the .mna or .mnx file.

Returns:

  • bool — True if successful.

Example​

Used in examples​

ex_mna​

MNA library: register operations, build and run a graph, bind parameters and save a project.
