Field Summary final static  int DEFAULT_INITIAL_CAPACITY      The default initial capacity - MUST be a power of two. final static  float DEFAULT_LOAD_FACTOR      The load factor used when none specified in constructor. final static  int MAXIMUM_CAPACITY      The maximum capacity, used if a higher value is implicitly specified by either of the constructors with arguments. final  float loadFactor      The load factor for the hash table. public  ReferenceQueue queue      transient  int size      The number of key-value mappings contained in this identity hash map.  int threshold      The next size value at which to resize (capacity * load factor). Constructor Summary public   LocalPMCache()      public   LocalPMCache(int initialCapacity)      public   LocalPMCache(int initialCapacity, float loadFactor)      Method Summary public  PCStateMan add(PCStateMan sm)      Add a newly created sm to the managed cache. public  PCStateMan add(OID oid, State state, PCStateMan[] sms)      public  PCStateMan addForProcessing(PCStateMan sm)      Add to the head of the processList. public  void addRealOID(PCStateMan sm)      This add the real oid of the NewOID to the mapping. public  PCStateMan addSm(OID key, PCStateMan value)      This method does not replace the PCStateMan if the OID is present. protected  PCStateMan addState(OID key, State value, boolean manage, PCStateMan[] addSm)      If the instance for this oid is already managed then it will be updated with the state information. public  void addStateOnly(OID oid, State state)      Provide the oid-state pair to local cache. public  void checkModelConsistency()      public static  void checkRefType(int currentRefType)      public  void clear()      public  boolean contains(OID oid)      Do we have a State or PCStateMan for the oid? Note the data may be evicted at any time depending on the reference type. public  PMCacheEntry createCacheKey(PCStateMan sm)      This must create a CacheEntryBase for the sm. public  PMCacheEntry createCacheKey(OID oid, State state)      This must create a CacheEntryBase for the sm. public  void doCommit(boolean retainValues)      public  void doRefresh(boolean strict)      public  void doRollback(boolean retainValues)      public  void dump()      static  boolean eq(OID x, OID y)      Check for equality of non-null reference x and possibly-null y. public  void evict()      public  PCStateMan getByNewObjectOID(NewObjectOID oid)      If the sm is already managed then return it. public  PCStateMan getByOID(OID oid, boolean manage)      If the sm is already managed then return it. public  int getCurrentRefType()      public  State getStateByOID(OID oid)      Return the state if present. public  boolean inProcessList(PCStateMan sm)      static  int indexFor(int h, int length)      Returns index for hash code h. public  boolean isOverWriteMode()      public  void processReferenceQueue()      Process the ReferenceQueue holding keys for GCed values. public  void remove(PCStateMan sm)      public  void setCurrentRefType(int currentRefType)      public  void setInterceptDfgFieldAccess(boolean on)      public  void setOverWriteMode(boolean overWriteMode)      public  void setPm(VersantPersistenceManagerImp pm)      public  int size()       PCStateMan updateSm(State value, PCStateMan sm, OID key)      Field Detail DEFAULT_INITIAL_CAPACITY final static int DEFAULT_INITIAL_CAPACITY(Code) The default initial capacity - MUST be a power of two. DEFAULT_LOAD_FACTOR final static float DEFAULT_LOAD_FACTOR(Code) The load factor used when none specified in constructor. MAXIMUM_CAPACITY final static int MAXIMUM_CAPACITY(Code) The maximum capacity, used if a higher value is implicitly specified by either of the constructors with arguments. MUST be a power of two <= 1<<30. loadFactor final float loadFactor(Code) The load factor for the hash table. queue public ReferenceQueue queue(Code) Reference queue for cleared WeakKeys size transient int size(Code) The number of key-value mappings contained in this identity hash map. threshold int threshold(Code) The next size value at which to resize (capacity * load factor). Constructor Detail LocalPMCache public LocalPMCache()(Code) LocalPMCache public LocalPMCache(int initialCapacity)(Code) LocalPMCache public LocalPMCache(int initialCapacity, float loadFactor)(Code) Method Detail add public PCStateMan add(PCStateMan sm)(Code) Add a newly created sm to the managed cache. add public PCStateMan add(OID oid, State state, PCStateMan[] sms)(Code) addForProcessing public PCStateMan addForProcessing(PCStateMan sm)(Code) Add to the head of the processList. addRealOID public void addRealOID(PCStateMan sm)(Code) This add the real oid of the NewOID to the mapping. addSm public PCStateMan addSm(OID key, PCStateMan value)(Code) This method does not replace the PCStateMan if the OID is present. If the mapping exist it will be verified. If the mapping does not exist it will be created. addState protected PCStateMan addState(OID key, State value, boolean manage, PCStateMan[] addSm)(Code) If the instance for this oid is already managed then it will be updated with the state information. Else the instance will be managed with this state. addStateOnly public void addStateOnly(OID oid, State state)(Code) Provide the oid-state pair to local cache. This will not result in a PCStateman being created. checkModelConsistency public void checkModelConsistency()(Code) checkRefType public static void checkRefType(int currentRefType)(Code) clear public void clear()(Code) contains public boolean contains(OID oid)(Code) Do we have a State or PCStateMan for the oid? Note the data may be evicted at any time depending on the reference type. createCacheKey public PMCacheEntry createCacheKey(PCStateMan sm)(Code) This must create a CacheEntryBase for the sm. createCacheKey public PMCacheEntry createCacheKey(OID oid, State state)(Code) This must create a CacheEntryBase for the sm. doCommit public void doCommit(boolean retainValues)(Code) doRefresh public void doRefresh(boolean strict)(Code) doRollback public void doRollback(boolean retainValues)(Code) dump public void dump()(Code) eq static boolean eq(OID x, OID y)(Code) Check for equality of non-null reference x and possibly-null y. evict public void evict()(Code) getByNewObjectOID public PCStateMan getByNewObjectOID(NewObjectOID oid)(Code) If the sm is already managed then return it. If the oid and state is present then manage it and return it. Else return null. This looks up using the oid as is and does not assume that realOID has been set. getByOID public PCStateMan getByOID(OID oid, boolean manage)(Code) If the sm is already managed then return it. If the oid and state is present then manage it and return it. Else return null. getCurrentRefType public int getCurrentRefType()(Code) getStateByOID public State getStateByOID(OID oid)(Code) Return the state if present. This will not result in the PCStateMan being created if not currently managed. inProcessList public boolean inProcessList(PCStateMan sm)(Code) indexFor static int indexFor(int h, int length)(Code) Returns index for hash code h. isOverWriteMode public boolean isOverWriteMode()(Code) processReferenceQueue public void processReferenceQueue()(Code) Process the ReferenceQueue holding keys for GCed values. remove public void remove(PCStateMan sm)(Code) setCurrentRefType public void setCurrentRefType(int currentRefType)(Code) setInterceptDfgFieldAccess public void setInterceptDfgFieldAccess(boolean on)(Code) setOverWriteMode public void setOverWriteMode(boolean overWriteMode)(Code) setPm public void setPm(VersantPersistenceManagerImp pm)(Code) size public int size()(Code) How many keys are in the cache? updateSm PCStateMan updateSm(State value, PCStateMan sm, OID key)(Code) Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
