List (Enum) parameters

Parameters that are defined though a choice list (usually a Type list in the Speos interface) can be changed using their corresponding enum. For instance, there are three different types of volume properties (opaque, optic and library) and three types of surface properties (mirror, optical polished, library) in the Material definition:

#Example of the use of enum to define optical properties
newMaterial = SpeosSim.Material.Create()
newMaterial.Name = "Plastic"
newMaterial.VOPType = SpeosSim.Material.EnumVOPType.Opaque
newMaterial.SOPType = SpeosSim.Material.EnumSOPType.Library 
newMaterial.SOPLibrary = ".\\SPEOS input files\\Plastic.simplescattering"

For lists that are not predefined, for example the possible locations of a Natural Light Ambient Source, the complete list of enums can be obtained though a Get method and parsed to find the useful value.

naturalLight = SpeosSim.SourceAmbientNaturalLight.Create() 
locations = naturalLight.GetLocationPossibleValues()
locationLabel = ""
for locationLabel in locations:
 print locationLabel
 if locationLabel.Contains("Boston"): 
 break
naturalLight.Location = locationLabel
