public abstract class OSVersionPredicate

extends Object

implements QuickSerializable

The OSVersionPredicate class is the abstract super class for all version predicates that are used in read requests to specify requirements of the versions to be read.

This class also defines a number of constants that are used in conjunction with the specific version predicates. For example, the constants LT, LEQ, EQ, GEQ, and GT correspond to the different types of comparisons that can be used to evaluate versions with predicates such as OSVPSeqNum.
