Class ObjectMappingInfo

The ObjectMappingInfo class is a helper class that holds the mapping information for a particular type. This information is in two parts:

  • Information about the Database Table that the object is mapped to
  • Information about how the object is cached. For each object, when it is first accessed, reflection is used on the class and an instance of ObjectMappingInfo is created, which is cached for performance.
