Example 1 with ValueWrapper

use of org.apache.geode.internal.cache.DiskEntry.Helper.ValueWrapper in project geode by apache.

the class Oplog method copyForwardModifyForCompact.

Example 2 with ValueWrapper

use of org.apache.geode.internal.cache.DiskEntry.Helper.ValueWrapper in project geode by apache.
