String |
getMappingType()
Return the abbreviated name of this mapping, or the full class name if it is a custom mapping. |
void |
insert(KodoStateManager sm,
RowManager rm)
Set values for the mapping into the proper rows. |
static boolean |
isJoinTable(Table table,
ReverseMappingTool tool)
Return true if the given table matches the pattern for a join table. |
Joins |
joinRelation(Joins joins)
Join this value's table to the table for the related first class object type, if any. |
Object |
loadProjection(JDBCStoreManager store,
JDBCFetchConfiguration fetch,
Result res,
Joins joins)

protected void |
selectProjection(Select sel,
JDBCStoreManager store,
JDBCFetchConfiguration fetch,
int eagerMode,
Joins joins)
Implement this method to select the projection of this field. |
void |
setForeignKey(ForeignKey fk)
Set the foreign key to the related object. |
boolean |
supportsSelect(Select sel,
int type,
KodoStateManager sm,
JDBCStoreManager store,
JDBCFetchConfiguration fetch)
