<div class="textblock"><p>A <code><a class="el" href="classgeos_1_1geomgraph_1_1Label.html" title="A Label indicates the topological relationship of a component of a topology graph to a given Geometry...">Label</a></code> indicates the topological relationship of a component of a topology graph to a given <code>Geometry</code>. </p>
<p>This class supports labels for relationships to two <code>Geometry</code>s, which is sufficient for algorithms for binary operations.</p>
<p>Topology graphs support the concept of labeling nodes and edges in the graph. The label of a node or edge specifies its topological relationship to one or more geometries. (In fact, since JTS operations have only two arguments labels are required for only two geometries). A label for a node or edge has one or two elements, depending on whether the node or edge occurs in one or both of the input <code>Geometry</code>s. Elements contain attributes which categorize the topological location of the node or edge relative to the parent <code>Geometry</code>; that is, whether the node or edge is in the interior, boundary or exterior of the <code>Geometry</code>. Attributes have a value from the set <code>{Interior, Boundary, Exterior}</code>. In a node each element has a single attribute <code>&lt;On&gt;</code>. For an edge each element has a triplet of attributes <code>&lt;Left, On, Right&gt;</code>.</p>
<p>It is up to the client code to associate the 0 and 1 <code><a class="el" href="classgeos_1_1geomgraph_1_1TopologyLocation.html" title="A TopologyLocation is the labelling of a GraphComponent&#39;s topological relationship to a single Geomet...">TopologyLocation</a></code>s with specific geometries. </p>
