VersionAwareCatalogConfigLoader:loadConfig Method
Loads the configuration for the VersionAwareCatalog service, defined in the Version Aware Object Relationship metadata (VersionAwareObjectRelationship__mdt).
Signature
public Boolean invokeMethod(String methodName, Map<String, Object> inputs, Map<String, Object> outputs, Map<String, Object> options)Usage
When the Version Aware Catalog Service is used by Vlocity Order Management to retrieve a Vlocity Catalog entity, the getSubGraph method of that service invokes the VersionAwareCatalogConfigLoader:loadConfig method.
