Method Detail

extractKey

public Object extractKey(Object value)

Extracts key from the value.

Specified by:

extractKey in interface JoinedMapping<Z,X,X>

Parameters:

value - the value

Returns:

the key of the value

fillValue

                ManagedInstance<?> managedInstance,
                Object instance)

Fills the sequence / table generated value.

The operation returns false if at least one entity needs to obtain identity from the database.

Specified by:

fillValue in interface SingularMappingEx<Z,X>

Parameters:

type - the entity type

managedInstance - the managed instance

instance - the instance to fill ids.

Returns:

false if all OK, true if if at least one entity needs to obtain identity from the database

flush

public void flush(Connection connection,
         ManagedInstance<?> managedInstance,
         boolean removals,
         boolean force)
           throws SQLException

Flushes the associates.

Specified by:

flush in interface JoinedMapping<Z,X,X>

Parameters:

connection - the connection to use

managedInstance - the managed instance

removals - true if the removals should be flushed and false for the additions

force - true to force, effective only for insertions and for new entities.

Throws:

SQLException - thrown if there is an underlying SQL Exception

Parameters:

path - the current path

Returns:

the association override or null

Since:
