Constructor Detail

GridNioSessionImpl

public GridNioSessionImpl(GridNioFilterChain filterChain,
                  @Nullable
                  InetSocketAddress locAddr,
                  @Nullable
                  InetSocketAddress rmtAddr,
                  boolean accepted)

Parameters:

filterChain - Chain.

locAddr - Local address.

rmtAddr - Remote address.

accepted - True if this session was initiated from remote host.

Method Detail

send

public GridNioFuture<?> send(Object msg)

Performs a request for asynchronous data send.

Specified by:

send in interface GridNioSession

Parameters:

msg - Message to be sent. This message will be eventually passed in to a parser plugged to the nio server.

Returns:

Future representing result.

resumeReads

public GridNioFuture<?> resumeReads()

Resumes session reads.

Specified by:

resumeReads in interface GridNioSession

Returns:

Future representing result.

pauseReads

public GridNioFuture<?> pauseReads()

Pauses reads.

Specified by:

pauseReads in interface GridNioSession

Returns:

Future representing result.

close

public GridNioFuture<Boolean> close()

Performs a request for asynchronous session close.

Specified by:

close in interface GridNioSession

Returns:

Future representing result.

localAddress

@Nullable
public InetSocketAddress localAddress()

Gets local address of this session.

Specified by:

localAddress in interface GridNioSession

Returns:

Local network address or null if non-socket communication is used.

remoteAddress

@Nullable
public InetSocketAddress remoteAddress()

Gets address of remote peer on this session.

Specified by:

remoteAddress in interface GridNioSession

Returns:

Address of remote peer or null if non-socket communication is used.

bytesSent

public long bytesSent()

Gets the total count of bytes sent since the session was created.

Specified by:

bytesSent in interface GridNioSession
