SuperclassDiscriminatorStrategy
public SuperclassDiscriminatorStrategy()
map
public void map(boolean adapt)
- Description copied from interface:
Strategy
- Map the owning mapping using this strategy.
- Specified by:
map in interface Strategy- Overrides:
map in class AbstractStrategy
- Parameters:
adapt - if true, use the owning mapping's raw mapping info
to set its ORM data; if false, ORM data will already be set
loadSubclasses
public void loadSubclasses(JDBCStore store)
throws SQLException,
ClassNotFoundException
- Description copied from class:
AbstractDiscriminatorStrategy
- By default, logs a warning that this discriminator cannot calculate
its list of subclasses on its own.
- Specified by:
loadSubclasses in interface DiscriminatorStrategy- Overrides:
loadSubclasses in class AbstractDiscriminatorStrategy
- Throws:
SQLException
ClassNotFoundException
getClass
public Class getClass(JDBCStore store,
ClassMapping base,
Result res)
throws SQLException,
ClassNotFoundException
- Description copied from interface:
DiscriminatorStrategy
- Return the class for the current result row.
- Specified by:
getClass in interface DiscriminatorStrategy- Overrides:
getClass in class AbstractDiscriminatorStrategy
- Throws:
SQLException
ClassNotFoundException
hasClassConditions
public boolean hasClassConditions(ClassMapping base,
boolean subclasses)
- Description copied from interface:
DiscriminatorStrategy
- Whether any class conditions are necessary.
- Specified by:
hasClassConditions in interface DiscriminatorStrategy- Overrides:
hasClassConditions in class AbstractDiscriminatorStrategy
- See Also:
DiscriminatorStrategy.getClassConditions(org.apache.openjpa.jdbc.sql.Select, org.apache.openjpa.jdbc.sql.Joins, org.apache.openjpa.jdbc.meta.ClassMapping, boolean)
getClassConditions
public SQLBuffer getClassConditions(Select sel,
Joins joins,
ClassMapping base,
boolean subclasses)
- Description copied from interface:
DiscriminatorStrategy
- Return SQL to limit the classes selected as much as possible to the
given base class, and optionally its subclasses. The select and joins
instances are supplied in order to get column aliases.
- Specified by:
