Class AbstractCloseableIteratorCollection<O,K,V>

java.lang.Object

java.util.AbstractCollection<O>

org.infinispan.commands.read.AbstractCloseableIteratorCollection<O,K,V>

All Implemented Interfaces:

Iterable<O>, Collection<O>, CloseableIteratorCollection<O>

Direct Known Subclasses:

DistributionBulkInterceptor.BackingEntrySet, DistributionBulkInterceptor.BackingKeySet, ValueCacheCollection

public abstract class AbstractCloseableIteratorCollection<O,K,V>
extends AbstractCollection<O>
implements CloseableIteratorCollection<O>

Abstract collection that uses an underlying Cache instance to do various operations. This is useful for a backing collection such as entrySet, keySet or values from the Map interface. Implementors only need to implement individual methods such as Collection.contains(Object), Collection.remove(Object) and CloseableIteratorCollection.iterator(). The Collection.add(Object) by default will throw an UnsupportedOperationException.

Method Detail

iterator

public abstract CloseableIterator<O> iterator()

Description copied from interface: CloseableIteratorCollection

This iterator should be explicitly closed when iteration upon it is completed. Failure to do so could cause resources to not be freed properly

Specified by:

iterator in interface Iterable<O>

Specified by:

iterator in interface Collection<O>

Specified by:

iterator in interface CloseableIteratorCollection<O>

Specified by:

iterator in class AbstractCollection<O>

spliterator

public abstract CloseableSpliterator<O> spliterator()

Description copied from interface: CloseableIteratorCollection

This spliterator should be explicitly closed after it has been used. Failure to do so could cause resources to not be freed properly

Specified by:

spliterator in interface Iterable<O>

Specified by:

spliterator in interface Collection<O>

Specified by:

spliterator in interface CloseableIteratorCollection<O>
