<h1>Property Merge 45</h1>
|
||
<p> </p>
|
||
<p>The following is the declaration of the property merge
|
||
algorithm.</p>
|
||
<p><font face="Courier New">template <typename
|
||
coordinate_type, typename property_type><br />
|
||
class property_merge_45;</font></p>
|
||
<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>
|
||
<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>
|
||
<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.</p>
