- Field Detail
  - hashLinkInfoCacheLock
```
protected static final Hashtable<OALinkInfo,ReentrantReadWriteLock> hashLinkInfoCacheLock
```
    Used by OALinkInfo to cache Hubs so that they are not strong linked within object. Key = OALinkInfo
  - hashLinkInfoCacheArrayList
```
protected static final Hashtable<OALinkInfo,ArrayList> hashLinkInfoCacheArrayList
```
  - hashLinkInfoCacheHashSet
```
protected static final Hashtable<OALinkInfo,HashSet> hashLinkInfoCacheHashSet
```
  - hashRootHub
```
protected static final Hashtable<OAObjectInfo,Hub> hashRootHub
```
    Used by OAObjectInfoDelegate to store the Root Hub for recursive classes. Key = Class Value = Hub (that is the 'top' (root) Hub of a recursive hub)
  - hashObjectInfo
```
protected static final ConcurrentHashMap<Class,OAObjectInfo> hashObjectInfo
```
    Static cache of OAObjectInfo, keyed on Class. Key = Class Value = OAObjectINfo
  - hashLock
```
protected static final Hashtable hashLock
```
    Locking support for OAObject. See OALock Key = OAObject Value = OALock
  - hashCacheClass
```
protected static final ConcurrentHashMap<Class,Object> hashCacheClass
```
    Used by Cache to store all OAObjects. Key = Class Value = TreeMap with all of the OAObjects in it.
  - hashCacheListener
```
protected static final ConcurrentHashMap hashCacheListener
```
    List of listeners for Cached objects Key = Class Value = Vector of listeners
  - hashCacheSelectAllHub
```
protected static final Hashtable hashCacheSelectAllHub
```
    Used by Cache to store all hubs that have selected all objects. Key = Class Value = WeakRef of Hubs
  - hashCacheNamedHub
```
protected static final Hashtable hashCacheNamedHub
```
    Used by Cache to store a Hub using a name. Key = upperCase(Name) Value = Hub
  - lstRehash
```
protected static ArrayList lstRehash
```
