JsonCall
February 7, 2026 · View on GitHub
JsonCall is a data model for encapsulating function calls with parameters and data as JSON-serializable objects. It provides methods for populating from JSON, accessing and modifying function names, parameters, data, and error strings, and serializing back to JSON format. It is primarily used for socket communication with MakeHuman.
