• Decoding an OGC filter from XML: see TLcdOGCFilterDecoder.
• Creating an OGC filter through the API: see TLcdOGCFilterFactory and the other classes in the com.luciad.ogc.filter.model package.
• Evaluating an OGC filter: see TLcdOGCFilterEvaluator.
• Converting an OGC filter to XML: see TLcdOGCFilterEncoder.
