protected void |
assertNotMappedBy()
Throws an informative exception if the field declares a mapped-by value. |
void |
customInsert(OpenJPAStateManager sm,
JDBCStore store)
Override this method to customize flushing this mapping. |
void |
customUpdate(OpenJPAStateManager sm,
JDBCStore store)
Override this method to customize flushing this mapping. |
void |
delete(OpenJPAStateManager sm,
JDBCStore store,
RowManager rm)
Set the where values appropriately to delete the proper instance, and set all relations on non-secondary tables as updates. |
void |
insert(OpenJPAStateManager sm,
JDBCStore store,
RowManager rm)
Set values for the mapping into the proper rows. |
Boolean |
isCustomInsert(OpenJPAStateManager sm,
JDBCStore store)
Return Boolean.FALSE if this mapping does not customize the
insert process, Boolean.TRUE if it does, or null if it does
customize the insert, but also relies on the standard insert method
being called. |
Boolean |
isCustomUpdate(OpenJPAStateManager sm,
JDBCStore store)
Return Boolean.FALSE if this mapping does not customize the
update process, Boolean.TRUE if it does, or null if it does
customize the update, but also relies on the standard update method
being called. |
void |
load(OpenJPAStateManager sm,
JDBCStore store,
JDBCFetchConfiguration fetch,
Result res)
Load virtual row data; the given result is not guaranteed to contain data for this field, so the field mapping should make sure the result contains its needed column data before loading. |
void |
map(boolean adapt)
Map the owning mapping using this strategy. |
int |
select(Select sel,
OpenJPAStateManager sm,
JDBCStore store,
JDBCFetchConfiguration fetch,
int eagerMode)
Select the virtual row columns of this mapping. |
void |
setFieldMapping(FieldMapping owner)
Set the class mapping using this strategy. |
int |
supportsSelect(Select sel,
int type,
OpenJPAStateManager sm,
JDBCStore store,
JDBCFetchConfiguration fetch)
Return whether this mapping can perform the given select type. |
void |
update(OpenJPAStateManager sm,
JDBCStore store,
RowManager rm)
Set values for the mapping into the proper rows. |
