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:
