Initializes this generation strategy for the given annotation instance.
Params:
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./**
