Examples of IndexIterator

com.antlersoft.odb.IndexIterator

An iterator resulting from a search on a key.

it.unimi.dsi.mg4j.index.IndexIterator

An iterator over an inverted list.

An index iterator scans the inverted list of an indexed term. Each integer returned by {@link DocumentIterator#nextDocument() nextDocument()} is the index of a document containing the term. If the index contains counts, they can be obtained after each call to {@link #nextDocument()} using {@link #count()}. Then, if the index contains positions they can be obtained as an array using {@link #positionArray()}, as an iterator using {@link #positions()}, or stored into an array using {@link #positions(int[])}.

Note that this interface extends {@link it.unimi.dsi.mg4j.search.DocumentIterator}. The intervals returned for a document are exactly length-one intervals corresponding to the positions returned by {@link #positions()}. If the index to which an instance of this class refers does not contain positions, an {@link UnsupportedOperationException}will be thrown.

Additionally, this interface strengthens {@link DocumentIterator#weight(double)} so thatit {@linkplain #weight(double) returns an index iterator}.

mikera.indexz.impl.IndexIterator

General purpose iterator for arbitrary indexes. @author Mike

org.apache.accumulo.core.file.rfile.MultiLevelIndex.Reader.IndexIterator

org.rhq.server.metrics.aggregation.IndexIterator

An iterator for the index with paging support. The iterator will scan through all partitions for a particular date range, one page at a time. If a query results in a read timeout, the iterator simply logs the exception and queries the next page. @author John Sanda

ucar.ma2.IndexIterator

Iteration through each element of an Array in "canonical order". The user obtains this by calling getIndexIterator() on an Array.

Canonical order for A[i][j][k] has k varying fastest, then j, then i.

Example: Replace array with its square:

 IndexIterator iter = A.getIndexIterator(); while (iter.hasNext()) { double val = iter.getDoubleNext(); iter.setDoubleCurrent( val * val); }

Note that canonical order may not be physical order. @author caron
