Constructor Detail

DefaultSctpServerChannelConfig

public DefaultSctpServerChannelConfig(SctpServerChannel channel,
                                      com.sun.nio.sctp.SctpServerChannel javaChannel)

Creates a new instance.

Method Detail

getOptions

public java.util.Map<ChannelOption<?>,java.lang.Object> getOptions()

Description copied from interface: ChannelConfig

Return all set ChannelOption's.

Specified by:

getOptions in interface ChannelConfig

Overrides:

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

getSendBufferSize

public int getSendBufferSize()

Description copied from interface: SctpServerChannelConfig

Gets the SO_SNDBUF option.

Specified by:

getSendBufferSize in interface SctpServerChannelConfig

setSendBufferSize

public SctpServerChannelConfig setSendBufferSize(int sendBufferSize)

Description copied from interface: SctpServerChannelConfig

Sets the SO_SNDBUF option.

Specified by:

setSendBufferSize in interface SctpServerChannelConfig

getReceiveBufferSize

public int getReceiveBufferSize()

Description copied from interface: SctpServerChannelConfig

Gets the SO_RCVBUF option.

Specified by:

getReceiveBufferSize in interface SctpServerChannelConfig

setReceiveBufferSize

public SctpServerChannelConfig setReceiveBufferSize(int receiveBufferSize)

Description copied from interface: SctpServerChannelConfig

Gets the SO_RCVBUF option.

Specified by:

setReceiveBufferSize in interface SctpServerChannelConfig

getInitMaxStreams

public com.sun.nio.sctp.SctpStandardSocketOptions.InitMaxStreams getInitMaxStreams()

Description copied from interface: SctpServerChannelConfig

Gets the SCTP_INIT_MAXSTREAMS option.

Specified by:

getInitMaxStreams in interface SctpServerChannelConfig

setInitMaxStreams

public SctpServerChannelConfig setInitMaxStreams(com.sun.nio.sctp.SctpStandardSocketOptions.InitMaxStreams initMaxStreams)

Description copied from interface: SctpServerChannelConfig

Gets the SCTP_INIT_MAXSTREAMS option.

Specified by:

setInitMaxStreams in interface SctpServerChannelConfig

getBacklog

public int getBacklog()

Description copied from interface: SctpServerChannelConfig

Gets the backlog value to specify when the channel binds to a local address.

Specified by:

getBacklog in interface SctpServerChannelConfig

setBacklog

public SctpServerChannelConfig setBacklog(int backlog)

Description copied from interface: SctpServerChannelConfig

Sets the backlog value to specify when the channel binds to a local address.

Specified by:

setMaxMessagesPerRead

public SctpServerChannelConfig setMaxMessagesPerRead(int maxMessagesPerRead)

Description copied from interface: ChannelConfig

Sets the maximum number of messages to read per read loop. If this value is greater than 1, an event loop might attempt to read multiple times to procure multiple messages.

Specified by:

Specified by:

setMaxMessagesPerRead in interface SctpServerChannelConfig

Overrides:

setMaxMessagesPerRead in class DefaultChannelConfig

setWriteSpinCount

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:

Specified by:

setConnectTimeoutMillis in interface ChannelConfig

Specified by:

setConnectTimeoutMillis in interface SctpServerChannelConfig

Overrides:

setConnectTimeoutMillis in class DefaultChannelConfig
