```text
## Getting MINA 2.0
You you can download the latest built version (2.0.2).
If you prefer to build the code from the trunk, and need assistance to do so, please consult the Developer Guide.
## Prerequisite
**Useful Information**  
Before accessing serial port from a Java program you need a native library (.DLL or .so depending of your OS). MINA use the one from RXTX.org : <ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7-bins-r2.zip>.   
Just put the good .dll or .so in the jre/lib/i386/ path of your JDK/JRE or use the -Djava.library.path= argument for specify where you placed the native libraries 
**Useful Information**  
The **mina-transport-serial** jar is not included in the full distribution. You can download it from [here](https://repo1.maven.org/maven2/org/apache/mina/mina-transport-serial/2.0.2/)

@Transition(on = "messageReceived")
public void messageReceived(List l, Number n) { ... }

// Matches since ((b instanceof Number) == true)
@Transition(on = "messageReceived")
public void messageReceived(Number n) { ... }

// Methods with no arguments always matches
@Transition(on = "messageReceived")
public void messageReceived() { ... }

// Methods only interested in the current Event or StateContext always matches
@Transition(on = "messageReceived")

Source: https://mina.apache.org/mina-project/userguide/ch14-state-machine/ch14-state-machine

This section introduces the mina-statemachine library as a tool for handling complex network interactions, suggesting it as an alternative to the State pattern.

```text
If you are using MINA to develop an application with complex network interactions you may at some point find yourself reaching for the good old [State pattern](http://home.earthlink.net/~huston2/dp/state.html) to try to sort out some of that complexity. However, before you do that you might want to checkout mina-statemachine which tries to address some of the shortcomings of the State pattern.

### NIO Overview

Source: https://mina.apache.org/mina-project/userguide/ch1-getting-started/ch1

Explains the core components of Java's New I/O (NIO) API, including Buffers, Charsets, Channels, and Selectors, and their relevance to the Apache MINA framework. MINA is built on NIO 1 and aims to abstract these low-level details for users.

```en
The `java.nio.*` package contains following key constructs
  * _Buffers_ - Data Containers
  * _Chartsets_ - Containers translators for bytes and Unicode
  * _Channels_ - represents connections to entities capable of I/O operations
  * _Selectors_ - provide selectable, multiplexed non-blocking IO
  * _Regexps_ - provide provide some tools to manipulate regular expressions

We are mostly interested in the _Channels_ , _Selectors_ and _Buffers_ parts in the **MINA** framework, except that we want to hide those elements to the user.
```

### Auto Shrinking Buffer Example

Source: https://mina.apache.org/mina-project/userguide/ch8-iobuffer/ch8-iobuffer

Demonstrates the usage of the autoShrink property and the shrink() method in IoBuffer to manage buffer capacity and conserve memory. It shows how the buffer's capacity changes when shrink() is called under different conditions.

```java
IoBuffer buffer = IoBuffer.allocate(16);
buffer.setAutoShrink(true);
buffer.put((byte)1);
System.out.println("Initial Buffer capacity = "+buffer.capacity());

buffer.shrink();
System.out.println("Initial Buffer capacity after shrink = "+buffer.capacity());

buffer.capacity(32);
System.out.println("Buffer capacity after incrementing capacity to 32 = "+buffer.capacity());

buffer.shrink();
System.out.println("Buffer capacity after shrink= "+buffer.capacity());

### Initialize MINA Datagram Acceptor with Spring Integration

Source: https://mina.apache.org/mina-project/userguide/ch17-spring-integration/ch17-spring-integration

This Java code snippet demonstrates the initialization of an Apache MINA NioDatagramAcceptor. It configures the acceptor with a handler, logging filter, protocol codec filter, and session configuration, then binds it to a specific port. This setup is typical for integrating MINA with Spring applications.

```java
public void initialize() throws IOException {

    // Create an Acceptor
    NioDatagramAcceptor acceptor = new NioDatagramAcceptor();

    // Add Handler
    acceptor.setHandler(new ServerHandler());

    acceptor.getFilterChain().addLast("logging",
                new LoggingFilter());
    acceptor.getFilterChain().addLast("codec",
                new ProtocolCodecFilter(new SNMPCodecFactory()));

    // Create Session Configuration
    SessionConfig dcfg = acceptor.getSessionConfig();
    dcfg.setReuseAddress(true);
    logger.debug("Starting Server......");
    // Bind and be ready to listen
    acceptor.bind(new InetSocketAddress(DEFAULT_PORT));
    logger.debug("Server listening on "+DEFAULT_PORT);
}

### IoService Interface Methods

Source: https://mina.apache.org/mina-project/userguide/ch3-service/ch3

This section documents the various methods available in the IoService interface. These methods allow for the management of I/O sessions, filters, handlers, and service lifecycle.

```APIDOC
IoService:
  getTransportMetadata()
    Returns the Transport meta-data the IoAcceptor or IoConnector is running. Typical details include provider name (nio, apr, rxtx), connection type (connectionless/connection oriented) etc.

  addListener(IoServiceListener listener)
    Allows to add an IoServiceListener to listen to specific events related to IoService.

  removeListener(IoServiceListener listener)
    Removes specified IoServiceListener attached to this IoService.

  isDisposing()
    Returns true if the service is currently being disposed.

  isDisposed()
    Returns true if the service has been disposed. A service will be considered as disposed only when all the resources it has allocated have been released.

  dispose()
    Releases all the resources the service has allocated. It may take a while, so the user should check the service status using isDisposing() and isDisposed() to know if the service is now disposed completely. Always call dispose() when you shutdown a service!

  getHandler()
    Returns the IoHandler associated with the service.

  setHandler(IoHandler handler)
    Sets the IoHandler that will be responsible for handling all the events for the service. The handler contains your application logic!

  getManagedSessions()
    Returns the map of all sessions which are currently managed by this service. A managed session is a session which is added to the service listener. It will be used to process the idle sessions, and other session aspects, depending on the kind of listeners a user adds to a service.

  getManagedSessionCount()
    Returns the number of all sessions which are currently managed by this service.

  getSessionConfig()
    Returns the session configuration.

  getFilterChainBuilder()
    Returns the Filter chain builder. This is useful if one wants to add some new filter that will be injected when the sessions will be created.

  setFilterChainBuilder(FilterChainBuilder builder)
    Defines the Filter chain builder to use with the service.

  getFilterChain()
    Returns the current default Filter chain for the service.

  isActive()
    Returns true if the service is active or not.

  getActivationTime()
    Returns the time when this service was activated. It returns the last time when this service was activated if the service is not anymore active.

  broadcast(Object message)
    Writes the given message to all the managed sessions.

  setSessionDataStructureFactory(IoSessionDataStructureFactory factory)
    Sets the IoSessionDataStructureFactory that provides related data structures for a new session created by this service.

  getScheduledWriteBytes()
    Returns the number of bytes scheduled to be written (ie, the bytes stored in memory waiting for the socket to be ready for write).

  getScheduledWriteMessages()
    Returns the number of messages scheduled to be written (ie, the messages stored in memory waiting for the socket to be ready for write).
```
