ColumnIO |
getColumnIO()
Return column I/O information for this mapping.
|
Column[] |
getColumns()
Return the columns used by this strategy.
|
Object[] |
getResultArguments()
Return the arguments needed to extract datastore values via
Result.getObject(java.lang.Object, int, java.lang.Object) for each column. |

loadEmbedded(OpenJPAStateManager sm,
JDBCStore store,
JDBCFetchConfiguration fetch,
Object val)
Load this strategy's field by transforming the given datastore value.
|
Object |
toEmbeddedDataStoreValue(Object val,
JDBCStore store)
Convert the given Java value to its datastore equivalent.
|

toEmbeddedObjectValue(Object val)
Convert the given datastore value to its Java equivalent.

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 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
UNSUPPORTED
if this mapping cannot support this method.void loadEmbedded(OpenJPAStateManager sm, JDBCStore store, JDBCFetchConfiguration fetch, Object val) throws SQLException
getColumns()
returns multiple columns, the given datastore
value will be an object array of the corresponding length. The value
does not have to be loaded immediately; it may be stored as impl data.SQLException
