* A CoordinateFieldType is the base class for {@link org.apache.solr.schema.FieldType}s that have semantics
22
* related to items in a coordinate system.
24
* Implementations depend on a delegating work to a sub {@link org.apache.solr.schema.FieldType}, specified by
25
* either the {@link #SUB_FIELD_SUFFIX} or the {@link #SUB_FIELD_TYPE} (the latter is used if both are defined.
28
* <pre><fieldType name="xy" class="solr.PointType" dimension="2" subFieldType="double"/>
30
* In theory, classes deriving from this should be able to do things like represent a point, a polygon, a line, etc.
32
* NOTE: There can only be one sub Field Type.
