Interface KeyHandleOffHeap

All Superinterfaces:

KeyHandle

All Known Implementing Classes:

SimpleHandleOffHeap

public interface KeyHandleOffHeap
extends KeyHandle

KeyHandle for an off-heap record. The key handle consists of a pair (address, sequenceId:

• address is a raw pointer to the data structure containing the key blob in the RAM store;
• sequenceId is a unique integer associated with the pointer. This is needed to prevent the A-B-A problem where the same pointer could be first invalidated, then later reused for an unrelated data structure, then dereferenced from this object.
