Interface IoAcceptor

All Superinterfaces:
IoService
All Known Subinterfaces:
DatagramAcceptor, SocketAcceptor
All Known Implementing Classes:
AbstractIoAcceptor, AbstractPollingIoAcceptor, AprSocketAcceptor, NioDatagramAcceptor, NioSocketAcceptor, VmPipeAcceptor

public interface IoAcceptor extends IoService
Accepts incoming connection, communicates with clients, and fires events to IoHandlers.

Please refer to EchoServer example.

You should bind to the desired socket address to accept incoming connections, and then events for incoming connections will be sent to the specified default IoHandler.

Threads accept incoming connections start automatically when bind() is invoked, and stop when unbind() is invoked.

  • Method Details

    • getLocalAddress

      SocketAddress getLocalAddress()
      Returns the local address which is bound currently. If more than one address are bound, only one of them will be returned, but it's not necessarily the firstly bound address.
      Returns:
      The bound LocalAddress
    • getLocalAddresses

      Set<SocketAddress> getLocalAddresses()
      Returns a Set of the local addresses which are bound currently.
      Returns:
      The Set of bound LocalAddresses
    • getDefaultLocalAddress

      SocketAddress getDefaultLocalAddress()
      Returns the default local address to bind when no argument is specified in bind() method. Please note that the default will not be used if any local address is specified. If more than one address are set, only one of them will be returned, but it's not necessarily the firstly specified address in setDefaultLocalAddresses(List).
      Returns:
      The default bound LocalAddress
    • getDefaultLocalAddresses

      List<SocketAddress> getDefaultLocalAddresses()
      Returns a List of the default local addresses to bind when no argument is specified in bind() method. Please note that the default will not be used if any local address is specified.
      Returns:
      The list of default bound LocalAddresses
    • setDefaultLocalAddress

      void setDefaultLocalAddress(SocketAddress localAddress)
      Sets the default local address to bind when no argument is specified in bind() method. Please note that the default will not be used if any local address is specified.

      firstLocalAddress - The first local address to bind the acceptor on
      otherLocalAddresses - The other local addresses to bind the acceptor on
    • setDefaultLocalAddresses

      void setDefaultLocalAddresses(Iterable<? extends SocketAddress> localAddresses)
      Sets the default local addresses to bind when no argument is specified in bind() method. Please note that the default will not be used if any local address is specified.
      Parameters:
      localAddresses - The local addresses to bind the acceptor on
    • setDefaultLocalAddresses

      void setDefaultLocalAddresses(List<? extends SocketAddress> localAddresses)
      Sets the default local addresses to bind when no argument is specified in bind() method. Please note that the default will not be used if any local address is specified.
      Parameters:
      localAddresses - The local addresses to bind the acceptor on
    • isCloseOnDeactivation

      boolean isCloseOnDeactivation()
      Returns true if and only if all clients are closed when this acceptor unbinds from all the related local address (i.e. when the service is deactivated).
      Returns:
      true if the service sets the closeOnDeactivation flag
    • setCloseOnDeactivation

      void setCloseOnDeactivation(boolean closeOnDeactivation)
      Sets whether all client sessions are closed when this acceptor unbinds from all the related local addresses (i.e. when the service is deactivated). The default value is true.
      Parameters:
      closeOnDeactivation - true if we should close on deactivation
    • bind

      void bind() throws IOException
      Binds to the default local address(es) and start to accept incoming connections.
      Throws:
      IOException - if failed to bind
    • bind

      void bind(SocketAddress localAddress) throws IOException
      Binds to the specified local address and start to accept incoming connections.
      Parameters:
      localAddress - The SocketAddress to bind to
      Throws:
      IOException - if failed to bind
    • bind

      void bind(SocketAddress firstLocalAddress, SocketAddress... addresses) throws IOException
      Binds to the specified local addresses and start to accept incoming connections. If no address is given, bind on the default local address.
      Parameters:
      firstLocalAddress - The first address to bind to
      addresses - The SocketAddresses to bind to
      Throws:
      IOException - if failed to bind
    • bind

      void bind(SocketAddress... addresses) throws IOException
      Binds to the specified local addresses and start to accept incoming connections. If no address is given, bind on the default local address.
      Parameters:
      addresses - The SocketAddresses to bind to
      Throws:
      IOException - if failed to bind
    • bind

      void bind(Iterable<? extends SocketAddress> localAddresses) throws IOException
      Binds to the specified local addresses and start to accept incoming connections.
      Parameters:
      localAddresses - The local address we will be bound to
      Throws:
      IOException - if failed to bind
    • unbind

      void unbind()
      Unbinds from all local addresses that this service is bound to and stops to accept incoming connections. All managed connections will be closed if disconnectOnUnbind property is true. This method returns silently if no local address is bound yet.
    • unbind

      void unbind(SocketAddress localAddress)
      Unbinds from the specified local address and stop to accept incoming connections. All managed connections will be closed if disconnectOnUnbind property is true. This method returns silently if the default local address is not bound yet.
      Parameters:
      localAddress - The local address we will be unbound from
    • unbind

      void unbind(SocketAddress firstLocalAddress, SocketAddress... otherLocalAddresses)
      Unbinds from the specified local addresses and stop to accept incoming connections. All managed connections will be closed if disconnectOnUnbind property is true. This method returns silently if the default local addresses are not bound yet.
      Parameters:
      firstLocalAddress - The first local address to be unbound from
      otherLocalAddresses - The other local address to be unbound from
    • unbind

      void unbind(Iterable<? extends SocketAddress> localAddresses)
      Unbinds from the specified local addresses and stop to accept incoming connections. All managed connections will be closed if disconnectOnUnbind property is true. This method returns silently if the default local addresses are not bound yet.
      Parameters:
      localAddresses - The local address we will be unbound from
    • newSession

      IoSession newSession(SocketAddress remoteAddress, SocketAddress localAddress)
      (Optional) Returns an IoSession that is bound to the specified localAddress and the specified remoteAddress which reuses the local address that is already bound by this service.

      This operation is optional. Please throw UnsupportedOperationException if the transport type doesn't support this operation. This operation is usually implemented for connectionless transport types.

      Parameters:
      remoteAddress - The remote address bound to the service
      localAddress - The local address the session will be bound to
      Returns:
      The session bound to the the given localAddress and remote address
      Throws:
      UnsupportedOperationException - if this operation is not supported
      IllegalStateException - if this service is not running.
      IllegalArgumentException - if this service is not bound to the specified localAddress.
