Example 51 with RegionVersionVector

use of org.apache.geode.internal.cache.versions.RegionVersionVector in project geode by apache.

the class PersistentRVVRecoveryDUnitTest method getDiskRVV.

protected RegionVersionVector getDiskRVV(VM vm) throws IOException, ClassNotFoundException {
    SerializableCallable createData = new SerializableCallable("getRVV") {

        public Object call() throws Exception {
            Cache cache = getCache();
            LocalRegion region = (LocalRegion) cache.getRegion(REGION_NAME);
            RegionVersionVector rvv = region.getDiskRegion().getRegionVersionVector();
            rvv = rvv.getCloneForTransmission();
            HeapDataOutputStream hdos = new HeapDataOutputStream(Version.CURRENT);
            // Using gemfire serialization because
            // RegionVersionVector is not java serializable
            DataSerializer.writeObject(rvv, hdos);
            return hdos.toByteArray();
        }
    };
    byte[] result = (byte[]) vm.invoke(createData);
    ByteArrayInputStream bais = new ByteArrayInputStream(result);
