spliterator

public Spliterator<InternalCacheEntry<WrappedBytes,WrappedBytes>> 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

spliterator

public Spliterator<InternalCacheEntry<WrappedBytes,WrappedBytes>> spliterator(IntSet segments)

Description copied from interface: org.infinispan.container.impl.InternalDataContainer

Same as DataContainer.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

spliteratorIncludingExpired

public Spliterator<InternalCacheEntry<WrappedBytes,WrappedBytes>> spliteratorIncludingExpired()

Description copied from interface: DataContainer

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

Returns:

spliterator that returns all entries including expired ones

spliteratorIncludingExpired

public Spliterator<InternalCacheEntry<WrappedBytes,WrappedBytes>> spliteratorIncludingExpired(IntSet segments)

Description copied from interface: org.infinispan.container.impl.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.

Parameters:

segments - segments of entries to use

Returns:

spliterator containing entries mapping to those segments that could be expired

iterator

public Iterator<InternalCacheEntry<WrappedBytes,WrappedBytes>> 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

iterator

public Iterator<InternalCacheEntry<WrappedBytes,WrappedBytes>> iterator(IntSet segments)

Description copied from interface: org.infinispan.container.impl.InternalDataContainer

Same as DataContainer.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

iteratorIncludingExpired

public Iterator<InternalCacheEntry<WrappedBytes,WrappedBytes>> iteratorIncludingExpired()

Description copied from interface: DataContainer

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

Returns:

iterator that returns all entries including expired ones

iteratorIncludingExpired

public Iterator<InternalCacheEntry<WrappedBytes,WrappedBytes>> iteratorIncludingExpired(IntSet segments)

Description copied from interface: org.infinispan.container.impl.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.

Parameters:

segments - segments of entries to use

Returns:

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

addSegments

public void addSegments(IntSet segments)

Description copied from interface: org.infinispan.container.impl.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(IntSet segments)

Description copied from interface: org.infinispan.container.impl.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).

Parameters:

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

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
