getOptions
public java.util.Map<ChannelOption<?>,java.lang.Object> getOptions()
Description copied from interface:ChannelConfig
Return all setChannelOption
's.- Specified by:
getOptions
in interfaceChannelConfig
- Overrides:
getOptions
in classDefaultChannelConfig
-
getOption
public <T> T getOption(ChannelOption<T> option)
Description copied from interface:ChannelConfig
Return the value of the givenChannelOption
- Specified by:
getOption
in interfaceChannelConfig
- Overrides:
getOption
in classDefaultChannelConfig
-
setOption
public <T> boolean setOption(ChannelOption<T> option, T value)
Description copied from interface:ChannelConfig
Sets a configuration property with the specified name and value. To override this method properly, you must call the super class:public boolean setOption(ChannelOption<T> option, T value) { if (super.setOption(option, value)) { return true; } if (option.equals(additionalOption)) { .... return true; } return false; }
- Specified by:
setOption
in interfaceChannelConfig
- Overrides:
setOption
in classDefaultChannelConfig
- Returns:
true
if and only if the property has been set
-
setRcvAllocTransportProvidesGuess
public KQueueChannelConfig setRcvAllocTransportProvidesGuess(boolean transportProvidesGuess)
If this istrue
then theRecvByteBufAllocator.Handle.guess()
will be overridden to always attempt to read as many bytes as kqueue says are available.
-
getRcvAllocTransportProvidesGuess
public boolean getRcvAllocTransportProvidesGuess()
If this istrue
then theRecvByteBufAllocator.Handle.guess()
will be overridden to always attempt to read as many bytes as kqueue says are available.
-
setConnectTimeoutMillis
public KQueueChannelConfig setConnectTimeoutMillis(int connectTimeoutMillis)
Description copied from interface:ChannelConfig
Sets the connect timeout of the channel in milliseconds. If theChannel
does not support connect operation, this property is not used at all, and therefore will be ignored.- Specified by:
setConnectTimeoutMillis
in interfaceChannelConfig
- Overrides:
setConnectTimeoutMillis
in classDefaultChannelConfig
- Parameters:
connectTimeoutMillis
- the connect timeout in milliseconds.0
to disable.
-
setMaxMessagesPerRead
@Deprecated public KQueueChannelConfig setMaxMessagesPerRead(int maxMessagesPerRead)
Deprecated.Description copied from class:DefaultChannelConfig
- Specified by:
setMaxMessagesPerRead
in interfaceChannelConfig
- Overrides:
setMaxMessagesPerRead
in classDefaultChannelConfig
-
setWriteSpinCount
public KQueueChannelConfig setWriteSpinCount(int writeSpinCount)
Description copied from interface:ChannelConfig
Sets the maximum loop count for a write operation untilWritableByteChannel.write(ByteBuffer)
returns a non-zero value. It is similar to what a spin lock is used for in concurrency programming. It improves memory utilization and write throughput depending on the platform that JVM runs on. The default value is16
.- Specified by:
setWriteSpinCount
in interfaceChannelConfig
- Overrides:
setWriteSpinCount
in classDefaultChannelConfig
-
setAllocator
public KQueueChannelConfig setAllocator(ByteBufAllocator allocator)
Description copied from interface:ChannelConfig
Set theByteBufAllocator
which is used for the channel to allocate buffers.- Specified by:
setAllocator
in interfaceChannelConfig
- Overrides:
setAllocator
in classDefaultChannelConfig
-
setRecvByteBufAllocator
public KQueueChannelConfig setRecvByteBufAllocator(RecvByteBufAllocator allocator)
Description copied from interface:ChannelConfig
Set theRecvByteBufAllocator
which is used for the channel to allocate receive buffers.- Specified by:
setRecvByteBufAllocator
in interfaceChannelConfig
- Overrides:
setRecvByteBufAllocator
in classDefaultChannelConfig
-
setAutoRead
public KQueueChannelConfig setAutoRead(boolean autoRead)
Description copied from interface:ChannelConfig
Sets ifChannelHandlerContext.read()
will be invoked automatically so that a user application doesn't need to call it at all. The default value istrue

setWriteBufferHighWaterMark
@Deprecated public KQueueChannelConfig setWriteBufferHighWaterMark(int writeBufferHighWaterMark)
Deprecated.Description copied from interface:ChannelConfig
Sets the high water mark of the write buffer. If the number of bytes queued in the write buffer exceeds this value,
Channel.isWritable()
will start to returnfalse
.- Specified by:
setWriteBufferHighWaterMark
in interfaceChannelConfig
- Overrides:
setWriteBufferHighWaterMark
in classDefaultChannelConfig
-
setWriteBufferLowWaterMark
@Deprecated public KQueueChannelConfig setWriteBufferLowWaterMark(int writeBufferLowWaterMark)
Deprecated.Description copied from interface:ChannelConfig
Sets the low water mark of the write buffer. Once the number of bytes queued in the write buffer exceeded the high water mark and then dropped down below this value,
Channel.isWritable()
will start to returntrue
again.- Specified by:
setWriteBufferLowWaterMark
in interfaceChannelConfig
- Overrides:
setWriteBufferLowWaterMark
in classDefaultChannelConfig
-
setWriteBufferWaterMark
public KQueueChannelConfig setWriteBufferWaterMark(WriteBufferWaterMark writeBufferWaterMark)
Description copied from interface:ChannelConfig
