Interface ILcdGDFFeatureThemeMap

All Known Implementing Classes:
TLcdGDFDefaultFeatureThemeMap
public interface ILcdGDFFeatureThemeMap
This interface maps feature classes on feature themes. It is used by the decoder to determine to which feature theme a feature class belongs. When using GDF data in which extra feature classes, not defined in the GDF specification, are used, the default implementation ( TLcdGDFDefaultFeatureThemeMap) should be extended to map these extra feature classes to the right feature theme. It's also possible to extend the default map with user-defined feature themes.
