Annotation Type ChannelHandler.Sharable

@Inherited
@Documented
@Target(value=TYPE)
@Retention(value=RUNTIME)
public static @interface ChannelHandler.Sharable

Indicates that the same instance of the annotated ChannelHandler can be added to one or more ChannelPipelines multiple times without a race condition.

If this annotation is not specified, you have to create a new handler instance every time you add it to a pipeline because it has unshared state such as member variables.

This annotation is provided for documentation purpose, just like the JCIP annotations.
