Constructor Details

BeforeSaveEvent

public BeforeSaveEvent(Iterable targetEntities,
 Set<String> includeProperties)

Constructor. BeforeSaveEvent does not hold mutations because this event gives the opportunity to modify the entities from which mutations are ultimately generated.

Parameters:

targetEntities - the target entities that need to be mutated. This may be null depending on the original request.

includeProperties - the set of properties to include in the save operation.
