used just as a gate check for classes (eg.This step is used just as a gate check to verify that a cluster belongs to a class.Checks that all the records from the upstream are of a particular type (or subclasses).Checks if a record can be safely deleted (throws OCommandExecutionException in case).takes a result set made of OUpdatableRecord instances and transforms it in another result set made of normal OResultInternal instances.takes a normal result set and transforms it in another result set made of OUpdatableRecord instances.Reads an upstream result set and returns a new result set that contains copies of the original OResult instancesReads an upstream result set and returns a new result set that contains copies of the original OResult instancesReturns the number of records contained in a class (including subclasses) Executes a count(*) on a class and returns a single record that contains that value (with a specific alias).Returns the number of records contained in an indexReturns
