类 ChannelOption<T>

java.lang.Object

io.netty.util.UniqueName

io.netty.channel.ChannelOption<T>

类型参数:

T - the type of the value which is valid for the ChannelOption

所有已实现的接口:

java.lang.Comparable<UniqueName>

直接已知子类:

EpollChannelOption, RxtxChannelOption, SctpChannelOption, UdtChannelOption

public class ChannelOption<T>
extends UniqueName

A ChannelOption allows to configure a ChannelConfig in a type-safe way. Which ChannelOption is supported depends on the actual implementation of ChannelConfig and may depend on the nature of the transport it belongs to.

方法详细资料

valueOf

public static <T> ChannelOption<T> valueOf(java.lang.String name)

Creates a new ChannelOption with the specified or return the already existing ChannelOption for the given name.

exists

public static boolean exists(java.lang.String name)

Returns true if a ChannelOption exists for the given name.

newInstance

public static <T> ChannelOption<T> newInstance(java.lang.String name)

Creates a new ChannelOption for the given or fail with an IllegalArgumentException if a ChannelOption for the given exists.

validate

public void validate(T value)

Validate the value which is set for the ChannelOption. Sub-classes may override this for special checks.
