Class IntSet


  • public final class IntSet
    extends java.lang.Object
    Read-optimized Set for storing Oid values. Note: the set does not support nullable values.

      • MAX_OID_TO_STORE_IN_BITSET

        private static final int MAX_OID_TO_STORE_IN_BITSET
        Maximal Oid that will bs stored in BitSet. If Oid exceeds this value, then it will be stored in Set<Int> only. In theory, Oids can be up to 32bit, so we want to limit per-connection memory utilization. Allow BitSet to consume up to 8KiB (one for send and one for receive).
