static PolygonSeeder * Create (Pvl &pvl)
 Create a PolygonSeeder object using a PVL specification.

Detailed Description

This class is used to create PolygonSeeder objects.

Applications which use autoseeding of points in polygons can use different techniques such as Grid or ????. If this factory is given a Pvl object which contains a PolygonSeeder definition it will create that specific instance of the class. For example,

 Object = PolygonSeeder
   Group = Algorithm
     Name = Grid
     ...
   EndGroup
   ...
 EndObject
 End

Will create a GridPolygonSeeder object (which is derived from PolygonSeeder). The simplest way to create an PolygonSeeder class is to use the static Create method

 Pvl p("myPolygonSeeder.pvl");
 PolygonSeeder *ps = PolygonSeederFactory::Create(p);

Member Function Documentation

PolygonSeeder * Isis::PolygonSeederFactory::Create ( Pvl &  pvl  )  [static]

Create a PolygonSeeder object using a PVL specification.

An example of the PVL required for this is:

 Object = AutoSeed
   Group = PolygonSeederAlgorithm
     Name      = Grid
     Tolerance = 0.7
   EndGroup

   Group = InterestOperatorAlgorithm
     Name      = StandardDeviation
     Tolerance = 10
   EndGroup

 EndObject
Parameters:
pvl The pvl object containing the PolygonSeeder specification
