public class DefaultSegmentedDataContainer<K,V> extends AbstractInternalDataContainer<K,V>
DataContainer implementation that internally stores entries in an array of maps. This array is indexed by the segment that the entries belong to. This provides for much better iteration of entries when a subset of segments are required.This implementation doesn't support bounding or temporary entries (L1).

iterator
public Iterator<InternalCacheEntry<K,V>> iterator(org.infinispan.commons.util.IntSet segments)
Description copied from interface:InternalDataContainer
Same asDataContainer.iterator()
except that only entries that map to the provided segments are returned via the iterator. The iterator will not return expired entries.- Parameters:
segments
- segments of entries to use- Returns:
- iterator that returns all entries mapped to the given segments
-
iterator
public Iterator<InternalCacheEntry<K,V>> iterator()
Description copied from interface:DataContainer
This iterator only returns entries that are not expired, however it will not remove them while doing so.
- Returns:
- iterator that doesn't produce expired entries
-
spliterator
public Spliterator<InternalCacheEntry<K,V>> spliterator(org.infinispan.commons.util.IntSet segments)
Description copied from interface:InternalDataContainer
Same asDataContainer.spliterator()
except that only entries that map to the provided segments are returned via this spliterator. The spliterator will not return expired entries.- Parameters:
segments
- segments of entries to return- Returns:
- spliterator containing entries mapping to those segments that aren't expired
-
spliterator
public Spliterator<InternalCacheEntry<K,V>> spliterator()
Description copied from interface:DataContainer
This spliterator only returns entries that are not expired, however it will not remove them while doing so.
- Returns:
- spliterator that doesn't produce expired entries
-
iteratorIncludingExpired
public Iterator<InternalCacheEntry<K,V>> iteratorIncludingExpired(org.infinispan.commons.util.IntSet segments)
Description copied from interface:InternalDataContainer
Same asDataContainer.iteratorIncludingExpired()
except that only entries that map to the provided segments are returned via the iterator. The iterator can return expired entries.- 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 asDataContainer.iterator()
except that is also returns expired entries.- Returns:
- iterator that returns all entries including expired ones
-
spliteratorIncludingExpired
public Spliterator<InternalCacheEntry<K,V>> spliteratorIncludingExpired(org.infinispan.commons.util.IntSet segments)
Description copied from interface:InternalDataContainer
Same asDataContainer.spliteratorIncludingExpired()
except that only entries that map to the provided segments are returned via this spliterator. The spliterator will return expired entries as well.- 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 asDataContainer.spliterator()
except that is also returns expired entries.- Returns:
- spliterator that returns all entries including expired ones
-
sizeIncludingExpired
public int sizeIncludingExpired(org.infinispan.commons.util.IntSet segment)
Description copied from interface:InternalDataContainer
Returns how many entries are present in the data container that map to the given segments including any entries that may be expired- Parameters:
segment
- segments of entries to count- Returns:
- count of the number of entries in the container including expired entries
-
sizeIncludingExpired
public int sizeIncludingExpired()
- Returns:
- count of the number of entries in the container including expired entries
-
clear
public void clear()
Description copied from interface:DataContainer
Removes all entries in the container
-
forEach
public void forEach(org.infinispan.commons.util.IntSet segments, Consumer<? super InternalCacheEntry<K,V>> action)
Description copied from interface:InternalDataContainer
Performs the given action for each element of the container that maps to the given set of segments until all elements have been processed or the action throws an exception. Unless otherwise specified by the implementing class, actions are performed in the order of iteration (if an iteration order is specified). Exceptions thrown by the action are relayed to the caller.action
- The action to be performed for each element
-
addSegments
public void addSegments(org.infinispan.commons.util.IntSet segments)
Description copied from interface:InternalDataContainer
Sets what segments this data container should be using. Already associated segments are unaffected by this and takes a union of existing and new segments.- Parameters:
segments
- segments to associate with this container
-
removeSegments
public void removeSegments(org.infinispan.commons.util.IntSet segments)
Description copied from interface:InternalDataContainer
Removes and un-associates the given segments. This will notify any listeners registered viaInternalDataContainer.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)
.- Parameters:
segments
- segments that should no longer be associated with this container
