- Method Detail
  - initialize
```
void initialize(A annotation,
                java.lang.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.
