## Class OpenMapRealVector.OpenMapEntry

- java.lang.Object
- - org.apache.commons.math3.linear.RealVector.Entry
  - - org.apache.commons.math3.linear.OpenMapRealVector.OpenMapEntry

Enclosing class:
  OpenMapRealVector

    protected class OpenMapRealVector.OpenMapEntry
    extends RealVector.Entry

Implementation of `Entry` optimized for OpenMap. This implementation does not allow arbitrary calls to `setIndex` since the order in which entries are returned is undefined.

### Field Summary

Fields
`private OpenIntToDoubleHashMap.Iterator` `iter` Iterator pointing to the entry.

### Constructor Summary

Constructors
`protected` `OpenMapRealVector.OpenMapEntry(OpenIntToDoubleHashMap.Iterator iter)` Build an entry from an iterator point to an element.

### Method Summary

Methods
`int` `getIndex()` Get the index of the entry.
`double` `getValue()` Get the value of the entry.
`void` `setValue(double value)` Set the value of the entry.
