• I/O Service - Performs actual I/O
• I/O Filter Chain - Filters/Transforms bytes into desired Data Structures and vice-versa
• I/O Handler - Here resides the actual business logic

create mina application process

• Create I/O service - Choose from already available Services (*Acceptor) or create your own
• Create Filter Chain - Choose from already existing Filters or create a custom Filter for transforming request/response
• Create I/O Handler - Write business logic, on handling different messages
  Creating a MINA application is this simple

Service

•  Server - IoAcceptor implement
• client -IoConnector implement

  Session

client 가  server 에 접속시 생성되며,  disconected 하기전까지 메모리에 상주한다.

• Connected : the session has been created and is available
• Idle : the session hasn’t processed any request for at least a period of time (this period is configurable)
  • Idle for read : no read has actually been made for a period of time
  • Idle for write : no write has actually been made for a period of time
  • Idle for both : no read nor write for a period of time
• Closing : the session is being closed (the remaining messages are being flushed, cleaning up is not terminated)
• Closed : The session is now closed, nothing else can be done to revive it.

IOBuffer

•  Buffers are just buffers
• ByteBuffer의 wrapper 객체인 IOBuffer는 3.x에 대폭 수정되거나,  deprecated 될것으로 보여진다.
• Assuming that the MINA ByteBuffer is just a wrapper on top of NIO ByteBuffer, this can be a real problem when using direct buffers.

mina  프로젝트를 보던중..build 시 .3.0.x,를 요구하더군요..

달라진게 먼지 아직 보진 못했으니..

이것도 공부해야할 대상..

$ mvn -Pserial clean install             # Build packages (JARs) for the core API and other extensions and install them to the local Maven repository.
$ mvn -Pserial site                      # Generate reports (JavaDoc and JXR)
$ mvn -Pserial package assembly:assembly # Generate a tarball (package goal needed to fix an assembly plugin bug)
$ mvn -Pserial eclipse:eclipse           # Generate Eclipse project files if you want
최초 이것만 알아도 별 문제없이 진행될듯..
