Description copied from interface: BeforeSaveCallback

Entity callback method invoked before a domain object is saved. Can return either the same or a modified instance of the domain object and can modify Document contents. This method is called after converting the entity to a Document so effectively the document is used as outcome of invoking this callback. Changes to the domain object are not taken into account for saving, only changes to the document. Only transient fields of the entity should be changed in this callback. To change persistent the entity before being converted, use the BeforeConvertCallback.

Specified by:

Parameters:

entity - the domain object to save.

document - Document representing the entity.

collection - name of the collection.
