Class L1SegmentedDataContainer<K,V>

java.lang.Object

org.infinispan.container.impl.AbstractInternalDataContainer<K,V>

org.infinispan.container.impl.DefaultSegmentedDataContainer<K,V>

org.infinispan.container.impl.L1SegmentedDataContainer<K,V>

All Implemented Interfaces:

Iterable<InternalCacheEntry<K,V>>, DataContainer<K,V>, InternalDataContainer<K,V>

public class L1SegmentedDataContainer<K,V>
extends DefaultSegmentedDataContainer<K,V>

Segmented data container that also allows for non owned segments to be written to a temporary map (L1). This temporary map is cleared whenever a segment becomes no longer owned.

If the segment is owned, only the owner segment is used. If the segment is not owned it will query the temporary map to see if the object is stored there.

Constructor Detail

L1SegmentedDataContainer

public L1SegmentedDataContainer(Supplier<PeekableTouchableMap<K,V>> mapSupplier,
                                int numSegments)

Method Detail

stop

public void stop()

Overrides:

stop in class DefaultSegmentedDataContainer<K,V>

getMapForSegment

public PeekableTouchableMap<K,V> getMapForSegment(int segment)

Overrides:

getMapForSegment in class DefaultSegmentedDataContainer<K,V>

iteratorIncludingExpired

public Iterator<InternalCacheEntry<K,V>> iteratorIncludingExpired(IntSet segments)

Description copied from interface: InternalDataContainer

Same as DataContainer.iteratorIncludingExpired() except that only entries that map to the provided segments are returned via the iterator. The iterator can return expired entries.

Specified by:

iteratorIncludingExpired in interface InternalDataContainer<K,V>

Overrides:

iteratorIncludingExpired in class DefaultSegmentedDataContainer<K,V>

Parameters:

segments - segments of entries to use

Returns:

iterator that returns all entries mapped to the given segments that could be expired

iteratorIncludingExpired

public Iterator<InternalCacheEntry<K,V>> iteratorIncludingExpired()

Description copied from interface: DataContainer

Same as DataContainer.iterator() except that is also returns expired entries.

Specified by:

iteratorIncludingExpired in interface DataContainer<K,V>

Overrides:

iteratorIncludingExpired in class DefaultSegmentedDataContainer<K,V>

Returns:

iterator that returns all entries including expired ones

spliteratorIncludingExpired

public Spliterator<InternalCacheEntry<K,V>> spliteratorIncludingExpired(IntSet segments)

Description copied from interface: InternalDataContainer

Same as DataContainer.spliteratorIncludingExpired() except that only entries that map to the provided segments are returned via this spliterator. The spliterator will return expired entries as well.

Specified by:

spliteratorIncludingExpired in interface InternalDataContainer<K,V>

Overrides:

spliteratorIncludingExpired in class DefaultSegmentedDataContainer<K,V>

Parameters:

segments - segments of entries to use

Returns:

spliterator containing entries mapping to those segments that could be expired

spliteratorIncludingExpired

public Spliterator<InternalCacheEntry<K,V>> spliteratorIncludingExpired()

Description copied from interface: DataContainer

Same as DataContainer.spliterator() except that is also returns expired entries.

Specified by:

spliteratorIncludingExpired in interface DataContainer<K,V>

Overrides:

spliteratorIncludingExpired in class DefaultSegmentedDataContainer<K,V>

Returns:

spliterator that returns all entries including expired ones

clear

public void clear()

Description copied from interface: DataContainer

Removes all entries in the container

Specified by:

clear in interface DataContainer<K,V>

Overrides:

clear in class DefaultSegmentedDataContainer<K,V>

clear

public void clear(IntSet segments)

Removes all entries that map to the given segments

Specified by:

clear in interface InternalDataContainer<K,V>

Overrides:

clear in class AbstractInternalDataContainer<K,V>

Parameters:

segments - the segments to clear data for

removeSegments

public void removeSegments(IntSet segments)

Description copied from interface: InternalDataContainer

Removes and un-associates the given segments. This will notify any listeners registered via InternalDataContainer.addRemovalListener(Consumer) of entries that were removed due to no longer being associated with this container. There is no guarantee if the consumer is invoked once or multiple times for a given group of segments and could be in any order.

When this method is invoked an implementation is free to remove any entries that don't map to segments currently associated with this container. Note that entries that were removed due to their segments never being associated with this container do not notify listeners registered via InternalDataContainer.addRemovalListener(Consumer).

Specified by:

removeSegments in interface InternalDataContainer<K,V>

Overrides:

removeSegments in class DefaultSegmentedDataContainer<K,V>

Parameters:

segments - segments that should no longer be associated with this container
