Method Detail

### 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:
    `getAlias` in interface `Strategy`
  Overrides:
    `getAlias` in class `AbstractStrategy`

### getJavaType

    protected int getJavaType()

  Description copied from class: `InValueDiscriminatorStrategy`
  Return the Java type code from `JavaTypes` for the discriminator values. This method is only used during mapping installation.

  Specified by:
    `getJavaType` in class `InValueDiscriminatorStrategy`

### getDiscriminatorValue

    protected Object getDiscriminatorValue(ClassMapping cls)

  Description copied from class: `InValueDiscriminatorStrategy`
  Return the discriminator value for the given type.

  Specified by:
    `getDiscriminatorValue` in class `InValueDiscriminatorStrategy`

### getClass

    protected Class getClass(Object val,
                             JDBCStore store)
                      throws ClassNotFoundException

  Description copied from class: `InValueDiscriminatorStrategy`
  Convert the given discriminator value to the corresponding class.

  Specified by:
    `getClass` in class `InValueDiscriminatorStrategy`
  Throws:
    `ClassNotFoundException`

### 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 `InValueDiscriminatorStrategy`
  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
