This class defines a disciminator used for the inheritance mapping. A discriminator is characterized by its strategy and the columns or field composing the discriminator.

Method Summary public  boolean basedOnColumnsOnly()      public  boolean basedOnFieldsAndColumns()      public  boolean basedOnFieldsOnly()      public  boolean hasDiscriminator()      final public static  int parseStrategy(String strategyName)      Parses a string representation of a strategy. Parameters:   strategyName - is a representation of a strategy the strategy corrresponding to the strategy name. public  void setDiscriminatorValue(Object value, SpeedoInheritance si, SpeedoElement elem)      final public static  String strategy2str(int s)      Parameters:   s - is a strategy string representation of the strategy. Field Detail STRATEGY_CLASS_NAME final public static int STRATEGY_CLASS_NAME(Code) This strategy of discriminator is a specialization of the STRATEGY_MAP_VALUE strategy. With this strategy the value associated to each persistent and concrete class is the class name. STRATEGY_MAP_VALUE final public static int STRATEGY_MAP_VALUE(Code) strategy of discriminator based on couples (class , value). To each value corresponds only one value and to each concrete class corresponds an unique value. Each classes has to defines its value. STRATEGY_NONE final public static int STRATEGY_NONE(Code) strategy without discriminator STRATEGY_UNKNOWN final public static int STRATEGY_UNKNOWN(Code) elements public List elements(Code) If discriminatorStrategy equals to #STRATEGY_NONE this field has no sense. Otherwise this field defines the columns of fields composing the discriminator. Elements of this list can be SpeedoField or SpeedoNoFieldColumn instances.

This field defines the strategy of the discriminator. The default value is #STRATEGY_NONE, corresponding to the case of there is no discriminator. Possible values are defined as constant in this class: See Also:   SpeedoDiscriminator.STRATEGY_NONE See Also:    See Also:   SpeedoDiscriminator.STRATEGY_MAP_VALUE See Also:    See Also:   SpeedoDiscriminator.STRATEGY_CLASS_NAME See Also:    Method Detail basedOnColumnsOnly public boolean basedOnColumnsOnly()(Code) boolean value indicating if there is a discriminator composedof columns only. basedOnFieldsAndColumns public boolean basedOnFieldsAndColumns()(Code) basedOnFieldsOnly public boolean basedOnFieldsOnly()(Code) boolean value indicating if there is a discriminator composedof fields. hasDiscriminator public boolean hasDiscriminator()(Code) a boolean value indicating if the strategy is not NONE and if there is elements composing the discriminator. parseStrategy final public static int parseStrategy(String strategyName)(Code) Parses a string representation of a strategy. Parameters:   strategyName - is a representation of a strategy the strategy corrresponding to the strategy name. If the strategy is notrecongnized STRATEGY_UNKNOWN is returned. setDiscriminatorValue public void setDiscriminatorValue(Object value, SpeedoInheritance si, SpeedoElement elem)(Code) strategy2str final public static String strategy2str(int s)(Code) Parameters:   s - is a strategy string representation of the strategy. If the strategy is notrecongnized a null value is returned.
