The Qt OPC UA data type generator
Starting with Qt 6.7, Qt OPC UA comes with a data type generator named qopcuaxmldatatypes2cpp which generates Qt OPC UA compatible C++ enumerations and data classes from enums and structured types in .bsd files.
The generator is a command line tool which can be controlled by the following argument:
| Long | Short | Purpose |
|---|---|---|
| –input | -i | A .bsd file for which all contained enum and struct types will be generated. Can be used more than once to generate code for multiple models. |
| –dependencyinput | -d | A dependency input .bsd file where only types required by a struct from an input file passed via —input will be generated. Can be used more than once to accommodate models with dependencies to multiple other models. |
| –output | -o | The output directory where the generated files will be placed. |
| –prefix | -p | The prefix for the generated file, enum and class names. The default value is GeneratedOpcUa. |
The following files are generated for each run:
- One .h file containing a namespace with all enumerated types
- One .h and one .cpp file for each structured type
- One .h and one .cpp file containing encoding and decoding methods
