public abstract class ALcdDAFIFSingleModelDecoder extends ALcdDAFIFDecoder
ALcdDAFIFDecoder class defines
the skeleton of the decode algorithm used to decode DAFIF data files.
The decode method will loop through all records in the source file.
A concrete decoder can decide on what to do with each record by implementing the
handleRecord method.
Extensions of the ALcdDAFIFSingleModelDecoder class will decode
so-called "single" model. Such a model has no submodels, as opposed to
the "multi" model.

If you don't have a properties object here, you can still specify it by decoding a .toc file containing the DAFIF properties. The decoder will read the properties from the .toc file and look for the data file to be decoded in the directory containing this .toc file.
aDAFIFProperties - a Properties object containing for each domain
object the name of its data file or NULLpublic ILcdModel decode(String aSource) throws IOException
The model will be build by looping through the records found in the source file.
Each record will be manipulated by the abstract handleRecord method.
Furthermore, the error message will be initialized and filled with reports about errors occurred during the decode proces.
aSource - either the directory containing the DAFIF source file to decode (if you did not
specify a properties file in the constructor, the default file name will be used), a .toc file
containing the DAFIF properties (the data file should be in the same directory as the .toc file)
or a single file which name corresponds to the file name associated with this decoder
(see getDecodeFileName()).IOException - if an error occurs during the reading processILcdModelDecoder.canDecodeSource(String)protected void cleanUp()

Please retrieve these feature names from the feature interfaces corresponding with the domain objects (e.g. com.luciad.ais.model.aerodrome.ILcdAerodromeFeature).
