Class LazyIterator

java.lang.Object
  org.infinispan.query.impl.AbstractIterator
      org.infinispan.query.impl.LazyIterator

All Implemented Interfaces:

Iterator<Object>, ListIterator<Object>, QueryIterator

@NotThreadSafe
public class LazyIterator
extends AbstractIterator

Implementation for QueryIterator. This is what is returned when the CacheQuery.lazyIterator() method is called. This loads the results only when required and hence differs from EagerIterator which is the other implementation of QueryResultIterator.

public Object next()

previous

public Object previous()

nextIndex

public int nextIndex()

previousIndex

public int previousIndex()

remove

public void remove()

This method is not supported and should not be used. Use cache.remove() instead.

set

public void set(Object o)
         throws UnsupportedOperationException

This method is not supported in and should not be called. Use cache.put() instead.

Parameters:

o -

Throws:

UnsupportedOperationException

add

public void add(Object o)
