public ViewerObjectRegistryDisabled()

Method Details

Clone

public PersistenceObjectRegistry Clone()

Description copied from interface: PersistenceObjectRegistry

Useful for PersistenceContextDispatcher.

Specified by:

Clone in interface Cloneable<PersistenceObjectRegistry>

Specified by:

Clone in interface PersistenceObjectRegistry

Returns:

A Clone of this instance as described in Cloneable.

lookupObjectId

public long lookupObjectId(Object object)

Specified by:

lookupObjectId in interface PersistenceObjectIdLookup

Specified by:

lookupObjectId in interface PersistenceObjectRegistry

lookupObject

public Object lookupObject(long objectId)

Specified by:

lookupObject in interface PersistenceObjectLookup

Specified by:

lookupObject in interface PersistenceObjectRegistry

containsObjectId

public boolean containsObjectId(long objectId)

Specified by:

containsObjectId in interface PersistenceObjectRegistry

iterateEntries

public <A extends PersistenceAcceptor> A iterateEntries(A acceptor)

Specified by:

iterateEntries in interface PersistenceObjectRegistry

size

public long size()

Specified by:

size in interface PersistenceObjectRegistry

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface PersistenceObjectRegistry

hashRange

public int hashRange()

Specified by:

hashRange in interface PersistenceObjectRegistry

hashDensity

public float hashDensity()

Specified by:

hashDensity in interface PersistenceObjectRegistry

minimumCapacity

public long minimumCapacity()

Specified by:

minimumCapacity in interface PersistenceObjectRegistry

capacity

public long capacity()

Description copied from interface: PersistenceObjectRegistry

Returns the current size potential before a (maybe costly) rebuild becomes necessary.

Specified by:

capacity in interface PersistenceObjectRegistry

setHashDensity

public boolean setHashDensity(float hashDensity)

Specified by:

setHashDensity in interface PersistenceObjectRegistry

setMinimumCapacity

public boolean setMinimumCapacity(long minimumCapacity)

Specified by:

setMinimumCapacity in interface PersistenceObjectRegistry

setConfiguration

public boolean setConfiguration(float hashDensity, long minimumCapacity)

Specified by:

setConfiguration in interface PersistenceObjectRegistry

ensureCapacity

public boolean ensureCapacity(long capacity)

Description copied from interface: PersistenceObjectRegistry

Makes sure the internal storage structure is prepared to provide a PersistenceObjectRegistry.capacity() of at least the passed capacity value.

Specified by:

ensureCapacity in interface PersistenceObjectRegistry

Returns:

whether a rebuild of internal storage structures was necessary.

registerObject

public boolean registerObject(long objectId, Object object)

Specified by:

registerObject in interface PersistenceObjectRegistry

optionalRegisterObject

public Object optionalRegisterObject(long objectId, Object object)

Specified by:

optionalRegisterObject in interface PersistenceObjectRegistry

registerConstant

public boolean registerConstant(long objectId, Object constant)

Specified by:

registerConstant in interface PersistenceObjectRegistry

consolidate

public boolean consolidate()

Description copied from interface: PersistenceObjectRegistry

Consolidate internal data structures, e.g. by removing orphan entries and empty hash chains. Depending on the implementation and the size of the registry, this can take a considerable amount of time.

Specified by:

consolidate in interface PersistenceObjectRegistry

Returns:

whether a rebuild was required.

clear

public void clear()

Description copied from interface: PersistenceObjectRegistry

Clears all entries except those that are essential for a correctly executed program (e.g. constants).
Clearing means to leave the current capacity as it is and just to actually clear its entries.

NOTE:
This method is currently only intended to be used for testing since calling it can cause inconsistencies if there still exist uncleared lazy references.

Specified by:

clear in interface PersistenceObjectRegistry

clearAll

public void clearAll()

Description copied from interface: PersistenceObjectRegistry

Clears all entries, including those that are essential for a correctly executed program (e.g. constants), effectively leaving a completely empty registry.
Clearing means to leave the current capacity as it is and just to actually clear its entries.

NOTE:
This method is currently only intended to be used for testing since calling it can cause inconsistencies if there still exist uncleared lazy references.

Specified by:

clearAll in interface PersistenceObjectRegistry

truncate

public void truncate()

Description copied from interface: PersistenceObjectRegistry

Truncates all entries except those that are essential for a correctly executed program (e.g. constants). Truncating means to quickly empty the registry by reinitializing the internal storage structures with a new and minimal capacity.

NOTE:
This method is currently only intended to be used for testing since calling it can cause inconsistencies if there still exist uncleared lazy references.

Specified by:

truncate in interface PersistenceObjectRegistry

truncateAll

public void truncateAll()

Description copied from interface: PersistenceObjectRegistry

Truncates all entries, including those that are essential for a correctly executed program (e.g. constants), effectively leaving a completely empty registry.
Truncating means to quickly empty the registry by reinitializing the internal storage structures with a new and minimal capacity.

NOTE:
This method is currently only intended to be used for testing since calling it can cause inconsistencies if there still exist uncleared lazy references.

Specified by:

truncateAll in interface PersistenceObjectRegistry

createHashStatistics

public XGettingTable<String,? extends HashStatistics> createHashStatistics()

Specified by:

createHashStatistics in interface PersistenceObjectRegistry

isValid

public boolean isValid(long objectId, Object object)

Specified by:

isValid in interface PersistenceObjectRegistry

validate

public void validate(long objectId, Object object)

Specified by:

validate in interface PersistenceObjectRegistry
