public abstract class ALcdDAFIFSingleModelDecoder extends ALcdDAFIFDecoder
ALcdDAFIFDecoderclass 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
Extensions of the
ALcdDAFIFSingleModelDecoder class will decode
so-called "single" model. Such a model has no submodels, as opposed to
the "multi" model.
|Constructor and Description|
Initializes the DAFIFProperties field with the specified properties object.
|Modifier and Type||Method and Description|
This method should be implemented by a concrete class.
Creates and returns the model descriptor to be set on the model returned in the
Returns a model containing domain objects read from the given source file.
Deals with one record of input.

public ALcdDAFIFSingleModelDecoder(Properties aDAFIFProperties)
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.

The model will be build by looping through the records found in the source file.
Each record will be manipulated by the abstract
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
IOException- if an error occurs during the reading process
protected void cleanUp()
It should empty all temporary data structures used during the decoding process.
protected abstract void handleRecord(int aFormat, char aRecord)
aFormat- the format of the record
aRecord- the record
protected abstract ILcdModelDescriptor createModelDescriptor(String aSource)
aSource- the source that will be used to decode
public void setKeyFeatureNames(String aKeyFeatureNames)
Arrayobject containing the names of the features that will be used as a key to insert objects into the model.
Please retrieve these feature names from the feature interfaces corresponding with the domain objects (e.g. com.luciad.ais.model.aerodrome.ILcdAerodromeFeature).
