  Throws:

  MappingException

• findIdentityByName

  protected FieldDescriptor findIdentityByName(List<FieldDescriptor> fldList, String idName, Class javaClass) throws MappingException

  Throws:

  MappingException

• resolveRelations

  protected void resolveRelations(ClassDescriptor clsDesc)

  Walks through all fields of a descriptor and resolves relation ClassDescriptors by using mapping information or, if not present, resolution by file to support generated ClassDescriptors. Resolved ClassDescriptors will be set as a field's descriptor.

  Specified by:

  resolveRelations in class AbstractMappingLoader

  Parameters:

  clsDesc - The ClassDescriptor in focus.

• getSqlTypes

  protected String[] getSqlTypes(FieldMapping fieldMap)

• getTypeInfo

  protected TypeInfo getTypeInfo(Class fieldType, CollectionHandler colHandler, FieldMapping fieldMap) throws MappingException

  Overrides:

  getTypeInfo in class AbstractMappingLoader

  Throws:

  MappingException

• createFieldDesc

  protected FieldDescriptorImpl createFieldDesc(Class javaClass, FieldMapping fieldMap) throws MappingException

  Description copied from class: AbstractMappingLoader

  Creates a single field descriptor. The field mapping is used to create a new stock FieldDescriptor. Implementations may extend this class to create a more suitable descriptor.

  Overrides:

  createFieldDesc in class AbstractMappingLoader

  Parameters:

  javaClass - The class to which the field belongs.

  fieldMap - The field mapping information.

  Returns:

  The field descriptor.

  Throws:
