public class ResultMementoBasicStandard
extends Object
implements ResultMementoBasic

Implementation of ResultMappingMemento for scalar (basic) results. Ultimately a scalar result is defined as a column name and a BasicType with the following notes:

• For JPA mappings, the column name is required. For `hbm.xml` mappings, it is optional (positional)
• Ultimately, when reading values, we need the BasicType. We know the BasicType in a few different ways:
  • If we know an explicit Type, that is used.
  • If we do not know the Type, but do know the Java type then we determine the BasicType based on the reported SQL type and its known mapping to the specified Java type
  • If we know neither, we use the reported SQL type and its recommended Java type to resolve the BasicType to use
