Class FilteringRangeIterator<T>

java.lang.Object
  info.magnolia.jcr.iterator.FilteringRangeIterator<T>

Type Parameters:

T -

All Implemented Interfaces:

Iterator, javax.jcr.RangeIterator

Direct Known Subclasses:

ContentDecoratorNodeIterator, ContentDecoratorPropertyIterator, FilteringNodeIterator, FilteringPropertyIterator

public abstract class FilteringRangeIterator<T>
extends Object
implements javax.jcr.RangeIterator

Base class for implementing filtering JCR iterators. Does not support the remove method because doing so would make it impossible to implement the getSize method. Should not be a problem since Jackrabbit anyway does not support the remove method on its iterators.
