ExceptionCodeProvider (Camunda Platform Javadocs 7.20.0-SNAPSHOT)

```
public interface ExceptionCodeProvider
```
One of the provider methods are called when a ProcessEngineException occurs. The default implementation provides the built-in exception codes.
You can disable the built-in or/and additionally register a custom provider via the ProcessEngineConfigurationImpl using the following properties:
- disableExceptionCode - disables the whole feature
- disableBuiltinExceptionCodeProvider - only disables the built-in provider and allows overriding reserved exception codes
- customExceptionCodeProvider - provide custom exception codes
