Class AisTcpReader

java.lang.Object

java.lang.Thread

dk.dma.ais.reader.AisReader

dk.dma.ais.reader.AisTcpReader

All Implemented Interfaces:

Runnable

public class AisTcpReader
extends AisReader

Thread class for reading AIS messages from a TCP stream.

Connection handling is fail tolerant. Connection error is handled by waiting a specified amount of time before doing a re-connect (default 5 sec).

Handlers for the parsed AIS messages must be registered with registerHanlder() method.

Example of use:

IAisHandler handler = new SomeHandler();

AisTcpReader aisReader = new AisTcpReader("localhost", 4001); aisReader.registerHandler(handler); aisReader.addProprietaryFactory(new GatehouseFactory()); aisReader.start(); aisReader.join();
