Method Detail

getOptions

public Map<ChannelOption<?>,Object> getOptions()

Description copied from interface: ChannelConfig

Return all set ChannelOption's.

Specified by:

getOptions in interface ChannelConfig

Overrides:

getOptions in class DefaultChannelConfig

getOption

public <T> T getOption(ChannelOption<T> option)

Description copied from interface: ChannelConfig

Return the value of the given ChannelOption

Specified by:

getOption in interface ChannelConfig

Overrides:

getOption in class DefaultChannelConfig

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 interface ChannelConfig

Overrides:

setOption in class DefaultChannelConfig

Returns:

true if and only if the property has been set

setRcvAllocTransportProvidesGuess

public KQueueChannelConfig setRcvAllocTransportProvidesGuess(boolean transportProvidesGuess)

If this is true then the RecvByteBufAllocator.Handle#guess() will be overriden to always attempt to read as many bytes as kqueue says are available.

getRcvAllocTransportProvidesGuess

public boolean getRcvAllocTransportProvidesGuess()

If this is true then the RecvByteBufAllocator.Handle#guess() will be overriden 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 the Channel does not support connect operation, this property is not used at all, and therefore will be ignored.

Specified by:

setConnectTimeoutMillis in interface ChannelConfig

Overrides:

setConnectTimeoutMillis in class DefaultChannelConfig

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 interface ChannelConfig

Overrides:

setMaxMessagesPerRead in class DefaultChannelConfig

setWriteSpinCount

public KQueueChannelConfig setWriteSpinCount(int writeSpinCount)

Description copied from interface: ChannelConfig

Sets the maximum loop count for a write operation until WritableByteChannel.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 is 16.

Specified by:

setWriteSpinCount in interface ChannelConfig

Overrides:

setWriteSpinCount in class DefaultChannelConfig

setAllocator

public KQueueChannelConfig setAllocator(ByteBufAllocator allocator)

Description copied from interface: ChannelConfig

Set the ByteBufAllocator which is used for the channel to allocate buffers.

Specified by:

setAllocator in interface ChannelConfig

Overrides:

setAllocator in class DefaultChannelConfig

setRecvByteBufAllocator

public KQueueChannelConfig setRecvByteBufAllocator(RecvByteBufAllocator allocator)

Description copied from interface: ChannelConfig

Set the RecvByteBufAllocator which is used for the channel to allocate receive buffers.

Specified by:

setRecvByteBufAllocator in interface ChannelConfig

Overrides:

setRecvByteBufAllocator in class DefaultChannelConfig

setAutoRead

public KQueueChannelConfig setAutoRead(boolean autoRead)

Description copied from interface: ChannelConfig

Sets if ChannelHandlerContext.read() will be invoked automatically so that a user application doesn't need to call it at all. The default value is true.

Specified by:

setAutoRead in interface ChannelConfig

Overrides:

setAutoRead in class DefaultChannelConfig

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 return false.

Specified by:

setWriteBufferHighWaterMark in interface ChannelConfig

Overrides:

setWriteBufferHighWaterMark in class DefaultChannelConfig

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 return true again.

Specified by:

setWriteBufferLowWaterMark in interface ChannelConfig

Overrides:

setWriteBufferLowWaterMark in class DefaultChannelConfig

setWriteBufferWaterMark

public KQueueChannelConfig setWriteBufferWaterMark(WriteBufferWaterMark writeBufferWaterMark)

Description copied from interface: ChannelConfig

Set the WriteBufferWaterMark which is used for setting the high and low water mark of the write buffer.

Specified by:

setWriteBufferWaterMark in interface ChannelConfig

Overrides:

setWriteBufferWaterMark in class DefaultChannelConfig

setMessageSizeEstimator

public KQueueChannelConfig setMessageSizeEstimator(MessageSizeEstimator estimator)

Description copied from interface: ChannelConfig

Set the MessageSizeEstimator which is used for the channel to detect the size of a message.

Specified by:

setMessageSizeEstimator in interface ChannelConfig

Overrides:

setMessageSizeEstimator in class DefaultChannelConfig

autoReadCleared

protected final void autoReadCleared()

Description copied from class: DefaultChannelConfig

Is called once DefaultChannelConfig.setAutoRead(boolean) is called with false and DefaultChannelConfig.isAutoRead() was true before.

Overrides:

autoReadCleared in class DefaultChannelConfig
