Interface AsyncIOInterceptor

All Known Implementing Classes:

AsyncIOInterceptorAdapter

public interface AsyncIOInterceptor

A filter-like API that allow an AtmosphereInterceptor to intercept the response before it gets written back to the client. An AsyncIOInterceptor can only be used with an AtmosphereInterceptorWriter.

An implementation of this class must make sure the data is written inside the intercept method because otherwise it will be lost.
