The HanaGenerator class in the hana_ml.artifacts.generators.hana module provides HANA specific generation functionality, extending the config file for HANA specific config generation, and includes methods for initializing the class and generating artifacts.
------
Here is a Python code template based on the provided help doc:

```python
from hana_ml.artifacts.generators.hana import HanaGenerator

# Define your parameters
project_name = "your_project_name"
version = "your_version"
grant_service = "your_grant_service"
connection_context = "your_connection_context"
outputdir = "your_output_directory"
generation_merge_type = 1
generation_group_type = 12
sda_grant_service = None
remote_source = ''

# Initialize the HanaGenerator
hg = HanaGenerator(project_name, version, grant_service, connection_context, outputdir, generation_merge_type, generation_group_type, sda_grant_service, remote_source)

# Generate the artifacts
output_path = hg.generate_artifacts(base_layer=True, consumption_layer=True, sda_data_source_mapping_only=False)

print(output_path)
```

Please replace `"your_project_name"`, `"your_version"`, `"your_grant_service"`, `"your_connection_context"`, and `"your_output_directory"` with your actual values.
