Interface InterceptorChain

public interface InterceptorChain

The interceptor chain manages the flow of a command through a chain of interceptors and ultimately to the command handler. Interceptors may continue processing via this chain by calling the proceed() or proceed(Object) methods. Alternatively, they can block processing by returning without calling either of these methods.
