Class TLcdARINCHeliportCommunicationHandler

java.lang.Object
com.luciad.format.arinc.decoder.TLcdARINCHeliportCommunicationHandler
All Implemented Interfaces:
ILcdARINCHandler
public class TLcdARINCHeliportCommunicationHandler extends Object
This extension of the ALcdARINCHandler interface deals with heliport communication records (Heliport Communications Records, section code H, subsection code V). Decoded models have as model descriptor an instance of TLcdARINCHeliportCommunicationModelDescriptor.

The objects in decoded models are based on the AIS domain objects available in com.luciad.ais.model, which all implement ILcdDataObject. This interface provides a generic and format-independent way of accessing the type and properties (features) of a domain object.

For this handler, the type of the decoded objects is TLcdARINCDataTypes.AerodromeCommunication, which can also be retrieved through ILcdDataObject.getDataType(). The available properties of the objects are defined in TLcdARINCAerodromeCommunicationDataProperties. The values for these properties can be retrieved through ILcdDataObject.getValue(com.luciad.datamodel.TLcdDataProperty).

Next to ILcdDataObject, the objects in decoded models also implement ILcdFeatured, the former interface to access the properties (features) of a domain object. This is still fully supported, and explained in the following comments.

The setCommunicationFeatureNamesToBeDecoded(String[]) setCommunicationFeatureNamesToBeDecoded} method allows the user to specify which ARINC features are decoded into the featured model objects.

If no feature names to be decoded are specified, all features will be decoded.

The following fields (taken from the ARINC specification 424) are supported by the decoder. The list indicates into which feature the fields are decoded. It also indicates from which ARINC version on they are available.

      public void handleRecord(char[] aRecord)
      Description copied from interface: ILcdARINCHandler
      Deals with one record of ARINC data.

      Each implementation of the ILcdARINCHandler interface decides by itself whether to use the information found in the given record to create or modify a domain object, or to do nothing at all.

      Typically, this method will be called when looping through the records of a data source.

      The domain objects created or modified when calling this method will be stored in a model. The user can obtain this model by calling the getModel method.
