AbstractCompositeDocumentIterator.AbstractCompositeIndexIntervalIterator (MG4J (big) 5.4.4)

java.lang.Object
- it.unimi.di.big.mg4j.search.AbstractCompositeDocumentIterator.AbstractCompositeIndexIntervalIterator

All Implemented Interfaces:

IntervalIterator

Direct Known Subclasses:

AndDocumentIterator.AndIndexIntervalIterator, ConsecutiveDocumentIterator.ConsecutiveIndexIntervalIterator, OrderedAndDocumentIterator.OrderedAndIndexIntervalIterator, OrDocumentIterator.OrIndexIntervalIterator

Enclosing class:

AbstractCompositeDocumentIterator
```
protected abstract static class AbstractCompositeDocumentIterator.AbstractCompositeIndexIntervalIterator
extends Object
implements IntervalIterator
```
An abstract IndexIterator-based interval iterator. The difference with AbstractCompositeDocumentIterator.AbstractCompositeIntervalIterator is that this class assumes that all document iterators are actually index iterators. The algorithms in this (very common) case can be significantly simplified, obtaining a large gain in performance.
