  extended by com.atlassian.jira.workflow.CachingDraftWorkflowStore
All Implemented Interfaces:
DraftWorkflowStore

public class CachingDraftWorkflowStore
extends Object
implements DraftWorkflowStore

Provides a caching implementation of the DraftWorkflowStore.

The lock is a ReadWriteLock, to speed up performance for gets which will be the most common operation.

Since:
v3.13
