| <section><p>The distance from a provided Point to a Point retrieved from a ValueSource via |
| <span class="xref">Lucene.Net.Queries.Function.FunctionValues.ObjectVal(System.Int32)</span>. The distance |
| is calculated via a <span class="xref">Spatial4n.Core.Distance.IDistanceCalculator</span>.</p> |

| <h4><a class="xref" href="Lucene.Net.Spatial.Util.ShapeFieldCache-1.html">ShapeFieldCache<T></a></h4> |
| <section><p>Bounded Cache of Shapes associated with docIds. Note, multiple Shapes can be |
| associated with a given docId |
| <p> |
| WARNING: This class holds the data in an extremely inefficient manner as all Points are in memory as objects and they |
| are stored in many Lists (one per document). So it works but doesn't scale. It will be replaced in the future. |

| between an input point and a document's points in |
| <a class="xref" href="Lucene.Net.Spatial.Util.ShapeFieldCacheProvider-1.html">ShapeFieldCacheProvider<T></a>. The shortest distance is returned if a |
