Package org.imixs.workflow.micro

Class MemoryDB

java.lang.Object
org.imixs.workflow.micro.MemoryDB
public class MemoryDB extends Object
In Memory DB.

The MemoryDB supports full concurrency of retrievals and updates of ItemCollection objects. The MemoryDB is based on the ConcurrentHashMap providing the same functional specification as a Hashtable, and includes versions of methods corresponding to each method of Hashtable. However, even though all operations are thread-safe, retrieval operations do not entail locking, and there is not any support for locking the entire table in a way that prevents all access. Find details in ConcurrentHashMap.
