| </p><h1>Property Merge 45</h1> |
| |
| <p> |
| <p>The following is the declaration of the property merge algorithm.<p> |
| <font face="Courier New">template <typename coordinate_type, typename |
| property_type><br> |
| class property_merge_45;</font><p>The property algorithm computes the n-layer |
| map overlay of input polygon sets. Each input geometry is inserted along |
| with a property value. The property type can be anything suitable for use |
| as an element of a std::set. Multiple geometry objects can be separately |
| inserted with the same property value. To store the result of this |
| operation a fairly complex container is required. Resulting geometries are |
| associated with unique subsets of property values of the input geometry. |
| Two suitable containers for storing the result of a property merge operation |
| are:<p><font face="Courier New">std::map<std::set<property_type>, polygon_45_set_data<coordinate_type> |
| ><br> |
| std::map<std::vector<property_type>, polygon_45_set_data<coordinate_type> ></font><p> |
| Example code <a href="gtl_property_merge_usage.htm">property_merge_usage.cpp</a> |
| demonstrates using the n-layer map-overlay algorithm on polygon 90 data.<h2>Member Functions</h2> |
