## 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.
