| 92 | <h1>Property Merge 45</h1> | |
| 93 | <p> </p> | |
| 94 | <p>The following is the declaration of the property merge | |
| 95 | algorithm.</p> | |
| 96 | <p><font face="Courier New">template <typename | |
| 97 | coordinate_type, typename property_type><br /> | |
| 98 | class property_merge_45;</font></p> | |
| 99 | <p>The property algorithm computes the n-layer map overlay of | |
| 100 | input polygon sets. Each input geometry is inserted along with a | |
| 101 | property value. The property type can be anything suitable for | |
| 102 | use as an element of a std::set. Multiple geometry objects can be | |
| 103 | separately inserted with the same property value. To store the | |
| 104 | result of this operation a fairly complex container is required. | |
| 105 | Resulting geometries are associated with unique subsets of property | |
| 106 | values of the input geometry. Two suitable containers for storing | |
| 107 | the result of a property merge operation are:</p> | |
| 108 | <p><font face="Courier New">std::map<std::set<property_type>, | |
| 109 | polygon_45_set_data<coordinate_type> ><br /> | |
| 110 | std::map<std::vector<property_type>, | |
| 111 | polygon_45_set_data<coordinate_type> ></font></p> | |
| 112 | <p>Example code <a href="gtl_property_merge_usage.htm">property_merge_usage.cpp</a> | |
| 113 | demonstrates using the n-layer map-overlay algorithm on polygon 90 data.</p> | |
