## org.apache.commons.math.linear
Class OpenMapRealVector.OpenMapSparseIterator

    java.lang.Object
      org.apache.commons.math.linear.OpenMapRealVector.OpenMapSparseIterator

All Implemented Interfaces:
  Iterator<RealVector.Entry>

Enclosing class:
  OpenMapRealVector

    protected class OpenMapRealVector.OpenMapSparseIterator

extends Object
implements Iterator<RealVector.Entry>

Iterator class to do iteration over just the non-zero elements.

This implementation is fail-fast, so cannot be used to modify any zero element.

Field Summary
`private RealVector.Entry` `current` Current entry.
`private OpenIntToDoubleHashMap.Iterator` `iter` Underlying iterator.

Constructor Summary
`protected` `OpenMapRealVector.OpenMapSparseIterator()` Simple constructor.

Method Summary
`boolean` `hasNext()`
`RealVector.Entry` `next()`
`void` `remove()`
