com.luciad.format.asterix.TLcdASTERIXSacSicRecordFilter

All Implemented Interfaces:

ILcdASTERIXRecordFilter

public class TLcdASTERIXSacSicRecordFilter
extends Object
implements ILcdASTERIXRecordFilter

ILcdASTERIXRecordFilter implementation that allows you to filter the ASTERIX records by data source (for instance, by the radar system that picked them up). The data source is defined by a SAC/SIC code (System Area Code / System Identification Code).

When multiple radar systems report on the same tracks in turn, a zig-zag effect might show up because of slight deviations in either radar system. To avoid this, filter out reports of either radar system using this filter.

Since:

2012.0

                      int aSystemIdentificationCode)

Add the specified combination of 'System Area Code' / 'System Identification Code' to this filter. Depending on the aNegate property of this filter, ASTERIX records will be accepted or rejected based on the added SAC/SIC combinations.

Parameters:

aSystemAreaCode - The System Area Code, as specified in the ASTERIX specification.

aSystemIdentificationCode - The System Identification Code, as specified in the ASTERIX specification.

Parameters:

aASTERIXRecord - The ILcdDataObject that represents the ASTERIX record. Its type corresponds to one of the UAP types in the TLcdASTERIXDataTypes class. No references should be kept to this object after this method has returned, as the same object might be reused in subsequent calls.
