in classJavaTypeMapping
- Parameters:
fmd
- FieldMetaData for the field to be mapped (if any)table
- The datastore container storing this mapping (if any)clr
- the ClassLoaderResolver
-
prepareColumnMapping
protected void prepareColumnMapping(org.datanucleus.ClassLoaderResolver clr) Convenience method to create a column for each implementation type of this reference.- Parameters:
clr
- The ClassLoaderResolver

getJavaType
Description copied from class:JavaTypeMapping
Accessor for the java type being mapped. This is the java type that the mapping represents. Some examples :- if the field is of type "MyClass" then the mapping will be OIDMapping (or subclass) the javaType will be OID, and the type will be MyClass.
- if the field is of type "int" then the mapping will be IntegerMapping, the javaType will be Integer, and the type will be int.
- Specified by:
getJavaType
in classJavaTypeMapping
- Returns:
- The java type
