Append a where clause to the given statement checking if this value is not null. |
void |
appendIsNull(SQLBuffer sql,
Select sel,
Joins joins)
Append a where clause to the given statement checking if this value is null. |
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. |
ColumnIO |
getColumnIO()
Return column I/O information for this mapping. |
Column[] |
getColumns()
The columns managed by this joinable. |
int |
getFieldIndex()
Return the field index of this joinable, or -1 if not a field. |
Object |
getJoinValue(Object fieldVal,
Column col,

Return the join value of the given column. |
Object |
getJoinValue(OpenJPAStateManager sm,
Column col,
JDBCStore store)
Return the join value of the given column. |
Object |
getPrimaryKeyValue(Result res,
Column[] cols,
ForeignKey fk,

Return the value for this joinable from the given result, using the given columns. |
Object[] |
getResultArguments()
Return the arguments needed to extract datastore values via Result.getObject(java.lang.Object, int, java.lang.Object) for each column. |

void |
load(OpenJPAStateManager sm,

where(OpenJPAStateManager sm,
JDBCStore store,
RowManager rm,
Object prevValue)

EmbeddableEmbeddable.getColumns() returns multiple columns, the given datastore
value will be an object array of the corresponding length. This method
must only be supported by mappings of embedded id objects. In other
cases Embeddable.loadEmbedded(org.apache.openjpa.kernel.OpenJPAStateManager, org.apache.openjpa.jdbc.kernel.JDBCStore, org.apache.openjpa.jdbc.kernel.JDBCFetchConfiguration, java.lang.Object) will be used instead. Return

does not have to be loaded immediately; it may be stored as impl data.
