Method Details

getMergeResultValueSchema

public SchemaEntry getMergeResultValueSchema(int firstValueSchemaID,
 int secondValueSchemaID)

For general purpose, refer to Javadoc of MergeResultValueSchemaResolver.getMergeResultValueSchema(int, int). This implementation handles 3 situations: 1. Old value schema ID is the same as new value schema ID. Return either schema. 2. Between old and new value schemas, one is a superset schema of another. Return the one that is the superset schema. 3. Old and new value schemas mismatch. Get and return the registered superset schema on this store.
