BeforeSaveEntity() 보호된 메소드

The method is called for each entity to be saved before the save occurs. If this method returns 'false' then the entity will be excluded from the save. The base implementation returns the result of BeforeSaveEntityDelegate, or 'true' if BeforeSaveEntityDelegate is null.

protected BeforeSaveEntity ( EntityInfo entityInfo ) : bool
entityInfo	EntityInfo
리턴	bool
