Method Details

isAllowHalfClosure

public boolean isAllowHalfClosure()

Description copied from interface: DuplexChannelConfig

Returns true if and only if the channel should not close itself when its remote peer shuts down output to make the connection half-closed. If false, the connection is closed automatically when the remote peer shuts down output.

Specified by:

isAllowHalfClosure in interface DuplexChannelConfig

setAllowHalfClosure

public NioDomainSocketChannel.NioDomainSocketChannelConfig setAllowHalfClosure(boolean allowHalfClosure)

Description copied from interface: DuplexChannelConfig

Sets whether the channel should not close itself when its remote peer shuts down output to make the connection half-closed. If true the connection is not closed when the remote peer shuts down output. Instead, ChannelInboundHandler.userEventTriggered(ChannelHandlerContext, Object) is invoked with a ChannelInputShutdownEvent object. If false, the connection is closed automatically.

Specified by:

setAllowHalfClosure in interface DuplexChannelConfig

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

getReceiveBufferSize

private int getReceiveBufferSize()

setReceiveBufferSize

private NioDomainSocketChannel.NioDomainSocketChannelConfig setReceiveBufferSize(int receiveBufferSize)

getSendBufferSize

private int getSendBufferSize()

setSendBufferSize

private NioDomainSocketChannel.NioDomainSocketChannelConfig setSendBufferSize(int sendBufferSize)

setConnectTimeoutMillis

public NioDomainSocketChannel.NioDomainSocketChannelConfig 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 NioDomainSocketChannel.NioDomainSocketChannelConfig setMaxMessagesPerRead(int maxMessagesPerRead)

Deprecated.

Description copied from class: DefaultChannelConfig

Specified by:

setMaxMessagesPerRead in interface ChannelConfig

Specified by:

setMaxMessagesPerRead in interface DuplexChannelConfig

Overrides:

setMaxMessagesPerRead in class DefaultChannelConfig

setWriteSpinCount

public NioDomainSocketChannel.NioDomainSocketChannelConfig 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

Specified by:

setWriteSpinCount in interface DuplexChannelConfig

Overrides:

setWriteSpinCount in class DefaultChannelConfig

setAllocator

public NioDomainSocketChannel.NioDomainSocketChannelConfig 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

Specified by:

setAllocator in interface DuplexChannelConfig

Overrides:

setAllocator in class DefaultChannelConfig

setRecvByteBufAllocator

public NioDomainSocketChannel.NioDomainSocketChannelConfig 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

Specified by:

setRecvByteBufAllocator in interface DuplexChannelConfig

Overrides:

setRecvByteBufAllocator in class DefaultChannelConfig

setAutoRead

public NioDomainSocketChannel.NioDomainSocketChannelConfig 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.

setAutoRead in interface DuplexChannelConfig

Overrides:

setAutoRead in class DefaultChannelConfig

setAutoClose

public NioDomainSocketChannel.NioDomainSocketChannelConfig setAutoClose(boolean autoClose)

Description copied from interface: ChannelConfig

Sets whether the Channel should be closed automatically and immediately on write failure. The default is true.

Specified by:

setAutoClose in interface ChannelConfig

Specified by:

setAutoClose in interface DuplexChannelConfig

Overrides:

setAutoClose in class DefaultChannelConfig

setWriteBufferHighWaterMark

public NioDomainSocketChannel.NioDomainSocketChannelConfig setWriteBufferHighWaterMark(int writeBufferHighWaterMark)

Overrides:

setWriteBufferHighWaterMark in class DefaultChannelConfig

setWriteBufferLowWaterMark

public NioDomainSocketChannel.NioDomainSocketChannelConfig setWriteBufferLowWaterMark(int writeBufferLowWaterMark)
