## Class SpatialOperation

- java.lang.Object
- - org.apache.lucene.spatial.query.SpatialOperation

- All Implemented Interfaces:
    Serializable

      public abstract class SpatialOperation
      extends Object
      implements Serializable

  A predicate that compares a stored geometry to a supplied geometry. It's enum-like. For more explanation of each predicate, consider looking at the source implementation of `evaluate(org.locationtech.spatial4j.shape.Shape, org.locationtech.spatial4j.shape.Shape)`. It's important to be aware that Lucene-spatial makes no distinction of shape boundaries, unlike many standardized definitions. Nor does it make dimensional distinctions (e.g. line vs polygon). You can lookup a predicate by "Covers" or "Contains", for example, and you will get the same underlying predicate implementation.

  WARNING: This API is experimental and might change in incompatible ways in the next release.

    Fields
    Modifier and Type | Field and Description
    --- | ---
    `static SpatialOperation` | `BBoxIntersects` Bounding box of the *indexed* shape, then `Intersects`.
    `static SpatialOperation` | `BBoxWithin` Bounding box of the *indexed* shape, then `IsWithin`.
    `static SpatialOperation` | `Contains` Meets the "Covers" OGC definition (boundary-neutral).
    `static SpatialOperation` | `Intersects` Meets the "Intersects" OGC definition.
    `static SpatialOperation` | `IsDisjointTo` Meets the "Disjoint" OGC definition.
    `static SpatialOperation` | `IsEqualTo` Meets the "Equals" OGC definition.
    `static SpatialOperation` | `IsWithin` Meets the "CoveredBy" OGC definition (boundary-neutral).
    `static SpatialOperation` | `Overlaps` Almost meets the "Overlaps" OGC definition, but boundary-neutral (boundary==interior).
