Method Detail

getOptions

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

Description copied from interface: ChannelConfig

Return all set ChannelOption's.

Specified by:

getOptions in interface ChannelConfig

getOptions

protected Map<ChannelOption<?>,Object> getOptions(Map<ChannelOption<?>,Object> result,
                                      ChannelOption<?>... options)

setOptions

public boolean setOptions(Map<ChannelOption<?>,?> options)

Description copied from interface: ChannelConfig

Sets the configuration properties from the specified Map.

Specified by:

setOptions in interface ChannelConfig

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

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(String name, Object value) {
     if (super.setOption(name, value)) {
         return true;
     }

     if (name.equals("additionalOption")) {
         ....
         return true;
     }

     return false;
 }
 

Specified by:

setOption in interface ChannelConfig

Returns:

true if and only if the property has been set

validate

protected <T> void validate(ChannelOption<T> option,
                T value)

getConnectTimeoutMillis

public int getConnectTimeoutMillis()

Description copied from interface: ChannelConfig

Returns 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:

getConnectTimeoutMillis in interface ChannelConfig

Returns:

the connect timeout in milliseconds. 0 if disabled.

setConnectTimeoutMillis

public void 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

Parameters:

connectTimeoutMillis - the connect timeout in milliseconds. 0 to disable.

getWriteSpinCount

public int getWriteSpinCount()

Description copied from interface: ChannelConfig

Returns 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:

getWriteSpinCount in interface ChannelConfig

setWriteSpinCount

public void 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.
