IEntitySave Method (IPredicate)

Saves the Entity class to the persistent storage. It updates or inserts the entity, which depends if the entity was originally read from the database. If the entity is new, an insert is done and the updateRestriction is ignored. If the entity is not new, the updateRestriction predicate is used to create an additional where clause (it will be added with AND) for the update query. This predicate can be used for concurrency checks, like checks on timestamp column values. Will not recursively save internal dirty entities.
