Method Details

newUnsafe
Description copied from class:AbstractChannel
Create a newAbstractChannel.AbstractUnsafe
instance which will be used for the life-time of theChannel
- Overrides:
newUnsafe
in classAbstractKQueueStreamChannel
-
localAddress0
Description copied from class:AbstractChannel
Returns theSocketAddress
which is bound locally.- Overrides:
localAddress0
in classAbstractKQueueChannel
-
remoteAddress0
Description copied from class:AbstractChannel
Return theSocketAddress
which theChannel
is connected to.- Overrides:
remoteAddress0
in classAbstractKQueueChannel
-
doBind
Description copied from class:AbstractChannel
Bind theChannel
to theSocketAddress
- Overrides:
doBind
in classAbstractKQueueChannel
- Throws:
Exception
-
config
Description copied from interface:Channel
Returns the configuration of this channel.- Specified by:
config
in interfaceChannel
- Specified by:
config
in interfaceDomainSocketChannel
- Specified by:
config
in classAbstractKQueueChannel
-
doConnect
protected boolean doConnect(SocketAddress remoteAddress, SocketAddress localAddress) throws Exception Description copied from class:AbstractKQueueChannel
Connect to the remote peer- Overrides:
doConnect
in classAbstractKQueueChannel
- Throws:
Exception
-
remoteAddress
Description copied from interface:Channel
Returns the remote address where this channel is connected to. The returnedSocketAddress
is supposed to be down-cast into more concrete type such asInetSocketAddress
to retrieve the detailed information.- Specified by:
remoteAddress
in interfaceChannel
- Specified by:
remoteAddress
in interfaceDomainSocketChannel
- Overrides:
remoteAddress
in classAbstractChannel
- Returns:
- the remote address of this channel.
null
if this channel is not connected. If this channel is not connected but it can receive messages from arbitrary remote addresses (e.g.DatagramChannel
, useDefaultAddressedEnvelope.recipient()
to determine the origination of the received message as this method will returnnull
.
-
localAddress
Description copied from interface:Channel
Returns the local address where this channel is bound to. The returnedSocketAddress
is supposed to be down-cast into more concrete type such asInetSocketAddress
to retrieve the detailed information.- Specified by:
localAddress
in interfaceChannel
- Specified by:
localAddress
in interfaceDomainSocketChannel
- Overrides:
localAddress
in classAbstractChannel
- Returns:
- the local address of this channel.
null
if this channel is not bound.
-
doWriteSingle
Description copied from class:AbstractKQueueStreamChannel
Attempt to write a single object.- Overrides:
doWriteSingle
in classAbstractKQueueStreamChannel
- Parameters:
in
- the collection which contains objects to write.- Returns:
- The value that should be decremented from the write quantum which starts at
ChannelConfig.getWriteSpinCount()
. The typical use cases are as follows:- 0 - if no write was attempted. This is appropriate if an empty
ByteBuf
(or other empty content) is encountered - 1 - if a single call to write data was made to the OS
ChannelUtils.WRITE_STATUS_SNDBUF_FULL
- if an attempt to write data was made to the OS, but no data was accepted
- 0 - if no write was attempted. This is appropriate if an empty
- Throws:
Exception
- If an I/O error occurs.
-
filterOutboundMessage
Description copied from class:AbstractChannel
Invoked when a new message is added to aChannelOutboundBuffer
of thisAbstractChannel
, so that theChannel
implementation converts the message to another. (e.g. heap buffer -> direct buffer)- Overrides:
filterOutboundMessage
in classAbstractKQueueStreamChannel
-
peerCredentials
Returns the unix credentials (uid, gid, pid) of the peer SO_PEERCRED- Throws:
IOException
-
