Modifier and Type | Method and Description |
---|---|
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). |
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). |
