Method Detail

initialize

void initialize(A annotation,
                Class<?> propertyType)

Initializes this generation strategy for the given annotation instance.

Parameters:

annotation - an instance of the strategy's annotation type. Typically implementations will retrieve the annotation's attribute values and store them in fields.

propertyType - the type of the property annotated with the generator annotation. Implementations may use the type to determine the right ValueGenerator to be applied.

Throws:

HibernateException - in case an error occurred during initialization, e.g. if an implementation can't create a value for the given property type.
