|
|
<p>Because it is not clear at this time what semantics for set-theoretic methods involving <code><a class="el" href="classgeos_1_1geom_1_1GeometryCollection.html" title="Represents a collection of heterogeneous Geometry objects. ">GeometryCollection</a></code>s would be useful, <code>GeometryCollections</code> are not supported as arguments to the set-theoretic methods.</p>
|
|
<h4>Representation of Computed Geometries </h4>
|
|
<p>The SFS states that the result of a set-theoretic method is the "point-set" result of the usual set-theoretic definition of the operation (SFS 3.2.21.1). However, there are sometimes many ways of representing a point set as a <code><a class="el" href="classgeos_1_1geom_1_1Geometry.html" title="Basic implementation of Geometry, constructed and destructed by GeometryFactory. ">Geometry</a></code>. </p>
|
|
<p>The SFS does not specify an unambiguous representation of a given point set returned from a spatial analysis method. One goal of JTS is to make this specification precise and unambiguous. JTS will use a canonical form for <code><a class="el" href="classgeos_1_1geom_1_1Geometry.html" title="Basic implementation of Geometry, constructed and destructed by GeometryFactory. ">Geometry</a></code>s returned from spatial analysis methods. The canonical form is a <code><a class="el" href="classgeos_1_1geom_1_1Geometry.html" title="Basic implementation of Geometry, constructed and destructed by GeometryFactory. ">Geometry</a></code> which is simple and noded: </p><ul>
|
|
<li>
|
|
Simple means that the <a class="el" href="classgeos_1_1geom_1_1Geometry.html" title="Basic implementation of Geometry, constructed and destructed by GeometryFactory. ">Geometry</a> returned will be simple according to the JTS definition of <code>isSimple</code>. </li>
|
|
<li>
|
|
Noded applies only to overlays involving <code><a class="el" href="classgeos_1_1geom_1_1LineString.html">LineString</a></code>s. It means that all intersection points on <code><a class="el" href="classgeos_1_1geom_1_1LineString.html">LineString</a></code>s will be present as endpoints of <code><a class="el" href="classgeos_1_1geom_1_1LineString.html">LineString</a></code>s in the result. </li>
|
|
</ul>
|
|
<p>This definition implies that non-simple geometries which are arguments to spatial analysis methods must be subjected to a line-dissolve process to ensure that the results are simple.</p>
|
|
<h4>Constructed Points And The Precision Model </h4>
|
|
<p>The results computed by the set-theoretic methods may contain constructed points which are not present in the input <a class="el" href="classgeos_1_1geom_1_1Geometry.html" title="Basic implementation of Geometry, constructed and destructed by GeometryFactory. ">Geometry</a>. These new points arise from intersections between line segments in the edges of the input <a class="el" href="classgeos_1_1geom_1_1Geometry.html" title="Basic implementation of Geometry, constructed and destructed by GeometryFactory. ">Geometry</a>. In the general case it is not possible to represent constructed points exactly. This is due to the fact that the coordinates of an intersection point may contain twice as many bits of precision as the coordinates of the input line segments. In order to represent these constructed points explicitly, JTS must truncate them to fit the <a class="el" href="classgeos_1_1geom_1_1PrecisionModel.html" title="Specifies the precision model of the Coordinate in a Geometry. ">PrecisionModel</a>.</p>
|
|
<p>Unfortunately, truncating coordinates moves them slightly. Line segments which would not be coincident in the exact result may become coincident in the truncated representation. This in turn leads to "topology collapses" – situations where a computed element has a lower dimension than it would in the exact result.</p>
|
|
<p>When JTS detects topology collapses during the computation of spatial analysis methods, it will throw an exception. If possible the exception will report the location of the collapse.</p>
|
|
<p>equals(Object) and hashCode are not overridden, so that when two topologically equal Geometries are added to HashMaps and HashSets, they remain distinct. This behaviour is desired in many cases. </p>

<p>Returns <code>true</code> if this geometry covers the specified geometry. </p>

<p>The <code>covers</code> predicate has the following equivalent definitions:</p>
|
|
<ul>
|
|
<li>Every point of the other geometry is a point of this geometry.</li>
|
|
<li>The DE-9IM Intersection Matrix for the two geometries is <code>T*****FF*</code> or <code>*T****FF*</code> or <code>***T**FF*</code> or <code>****T*FF*</code></li>

In particular, unlike <code>contains</code> it does not distinguish between points in the boundary and in the interior of geometries. For most situations, <code>covers</code> should be used in preference to <code>contains</code>. As an added benefit, <code>covers</code> is more amenable to optimization, and hence should be more performant.</p>
