Constructor Detail

SecondaryRow

public SecondaryRow(Table table,
                    int action)

Constructor; supply table and action.

                       int action)

Method Detail

setForeignKey

public void setForeignKey(ForeignKey fk,
                          OpenJPAStateManager sm)
                   throws SQLException

Description copied from interface: Row

Set the value of the given foreign key to the given object. If the related type uses table-per-class mappings, the foreign key may be targeted at an independent superclass table.

Specified by:

setForeignKey in interface Row

Overrides:

setForeignKey in class RowImpl

Throws:

SQLException

setForeignKey

public void setForeignKey(ForeignKey fk,
                          ColumnIO io,
                          OpenJPAStateManager sm)
                   throws SQLException

Description copied from interface: Row

Set the value of the given foreign key to the given object. If the related type uses table-per-class mappings, the foreign key may be targeted at an independent superclass table.

Specified by:

setForeignKey in interface Row

Overrides:

setForeignKey in class RowImpl

io - information on which columns are settable; may be null

Throws:

SQLException

setRelationId

public void setRelationId(Column col,
                          OpenJPAStateManager sm,
                          RelationId rel)
                   throws SQLException

Description copied from interface: Row

Set the value of the given column to the identity of given instance, using the given callback to create the column value. This method is used for mappings that store some serialized form of id values, but must make sure that the related object's id is assigned (which might require an insert if the instance uses auto-increment) before it is serialized.

Specified by:

setRelationId in interface Row

Overrides:

setRelationId in class RowImpl

Throws:

SQLException

generateSQL

protected String generateSQL(DBDictionary dict)

Description copied from class: RowImpl

Generate the SQL for this row; the result of this method is cached.

Overrides:

generateSQL in class RowImpl

newInstance

protected RowImpl newInstance(Column[] cols,
                              int action)

Description copied from class: RowImpl

Return a new row.

Overrides:

newInstance in class RowImpl

copyInto

public void copyInto(RowImpl row,
                     boolean whereOnly)

Description copied from class: RowImpl

Copy all values from this row into the given one.

Overrides:

copyInto in class RowImpl

whereOnly - if true, only copy where conditions
