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. |
Column[] |
getElementColumns(ClassMapping elem)
Return the columns holding the data for a collection element for the given element mapping from LRSCollectionFieldStrategy.getIndependentElementMappings(boolean)
(or null). |
FieldMapping |
getFieldMapping()
The owning field mapping. |
ClassMapping[] |
getIndependentElementMappings(boolean traverse)
Return all independent mappings to which this strategy must join in order to access collection elements, or empty array if none. |
ForeignKey |
getJoinForeignKey(ClassMapping elem)
Return the foreign key used to join to the owning field for the given element mapping from ContainerFieldStrategy.getIndependentElementMappings(boolean) (or null). |
void |
insert(OpenJPAStateManager sm,
JDBCStore store,
RowManager rm)
Set values for the mapping into the proper rows. |
Joins |
join(Joins joins,
ClassMapping elem)
Join to the owning field table for the given element mapping from ContainerFieldStrategy.getIndependentElementMappings(boolean) (or null). |
Joins |
joinElementRelation(Joins joins,
ClassMapping elem)
Join this value's table to the table for the given element mapping from ContainerFieldStrategy.getIndependentElementMappings(boolean) (or null). |
Object |
loadElement(OpenJPAStateManager sm,
JDBCStore store,
JDBCFetchConfiguration fetch,
Result res,
Joins joins)
Load an element of the collection. |
void |
map(boolean adapt)
Map the owning mapping using this strategy. |
protected Proxy |
newLRSProxy()
Return a large result set proxy for this field. |
void |
selectElement(Select sel,
ClassMapping elem,
JDBCStore store,
JDBCFetchConfiguration fetch,
int eagerMode,
Joins joins)
Implement this method to select the elements of this field for the given element mapping from ContainerFieldStrategy.getIndependentElementMappings(boolean)
(or null). |
