Configuration Internals

The configuration subsystem is located in snakeway-core/src/conf.

The configuration loading process is broken down into the following steps:

1. Spec
   • The operator-facing config file specification.
   • Defined in snakeway-core/src/conf/types/specification
2. Parse
   • Ingest the config files and convert to an in-memory spec representation.
   • Fail early on parse errors.
3. Validate
   • Pass the spec representation through a series of validation steps.
   • Collect validation errors and warnings.
4. Lower
   • Transform the spec representation into a runtime representation.
   • Define in snakeway-core/src/conf/types/runtime
5. Runtime
   • Runtime representation is returned by the load_config function.
