ALIAS
public static final String ALIAS
- See Also:
- Constant Field Values
FlatClassStrategy
public FlatClassStrategy()
getAlias
public String getAlias()
- Description copied from interface: Strategy
- Return the alias of this strategy. For custom strategies, return the
 full class name.

- Specified by:
- getAliasin interface- Strategy
- Overrides:
- getAliasin class- AbstractStrategy

map
public void map(boolean adapt)
- Description copied from interface: Strategy
- Map the owning mapping using this strategy.
 
- 
- Specified by:
- mapin interface- Strategy
- Overrides:
- mapin 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
 
isPrimaryKeyObjectId
public boolean isPrimaryKeyObjectId(boolean hasAll)
- Description copied from interface: ClassStrategy
- Return true if the this class' primary key columns correspond to the
 base class' primary key columns used to construct oid values. Base
 classes always return true. Classes that join to the base class table,
 though, may not always join using the same columns the base class
 uses for oid values, or may not use all the columns. When performing a
 select, we will join down to the most-derived class that is identified
 by oid values. We cannot use non-primary key field values for joining
 during selects, because the field values to join on might be the ones
 we're trying to select! Similarly, we can only reconstruct oid values
 for selected objects using classes whose primary keys store oid values.

- Specified by:
- isPrimaryKeyObjectIdin interface- ClassStrategy
- Overrides:
- isPrimaryKeyObjectIdin class- AbstractClassStrategy
 
- 
- Parameters:
- hasAll- if true, there must be a primary key column for every
 base class primary key column; if false the primary key
 must only match a subset of the base class primary key columns
