类 AbstractAISMessageListener<T extends AISMessage>

java.lang.Object

net.sf.marineapi.nmea.event.AbstractSentenceListener<AISSentence>

net.sf.marineapi.ais.event.AbstractAISMessageListener<T>

类型参数:

T - AIS message type to be listened.

所有已实现的接口:

EventListener, SentenceListener

直接已知子类:

AISListenerExample

public abstract class AbstractAISMessageListener<T extends AISMessage>
extends AbstractSentenceListener<AISSentence>

Abstract listener for AIS messages. Extend this class to create a listener for a specific AIS message type and register it in a SentenceReader.

To listen to all incoming AIS sentences, extend the AbstractSentenceListener using AISSentence as type. However, in this case you also need to implement the message concatenation to parse messages being delivered over multiple sentences.

This class is based on AbstractSentenceListener and thus it has the same recommendations and limitations regarding the usage of generics and inheritance.

构造器详细资料

AbstractAISMessageListener

public AbstractAISMessageListener()

Default constructor with automatic generic type resolving. Notice that the GenericTypeResolver may not always succeed.

抛出:

IllegalStateException - If the generic type cannot be resolved at runtime.

• AbstractAISMessageListener(Class)

AbstractAISMessageListener

public AbstractAISMessageListener(Class<T> c)

Constructor with explicit generic type parameter. This constructor may be used when the default constructor fails to resolve the generic type T at runtime.

参数:

c - Message type T to be listened.

方法详细资料

sentenceRead

public final void sentenceRead(AISSentence sentence)

Invoked when AISSentence of any type is received. Pre-parses the message to determine it's type and invokes the onMessage(net.sf.marineapi.ais.message.AISMessage) method when the type matches the generic type T.

This method has been declared final to ensure the correct handling of received sentences.

指定者:

sentenceRead 在类中 AbstractSentenceListener<AISSentence>

参数:

sentence - Sentence of type T

onMessage

public abstract void onMessage(T msg)

Invoked when AIS message has been received.

参数:

msg - AISMessage of type T

readingPaused

public void readingPaused()

Empty implementation.

指定者:

readingPaused 在接口中 SentenceListener

覆盖:

readingPaused 在类中 AbstractSentenceListener<AISSentence>

另请参阅:

• SentenceListener.readingPaused()

readingStarted

public void readingStarted()

Empty implementation.

指定者:

readingStarted 在接口中 SentenceListener

覆盖:

readingStarted 在类中 AbstractSentenceListener<AISSentence>

另请参阅:

• SentenceListener.readingStarted()

readingStopped

public void readingStopped()

Empty implementation.

指定者:

readingStopped 在接口中 SentenceListener

覆盖:

readingStopped 在类中 AbstractSentenceListener<AISSentence>
