执行顺序

不论是客户端，还是服务器，都可以添加多个过滤器。假设我们按照添加的顺序把它们叫做 filter1, filter2, … filterN。那么它们的执行顺序是这样的。

在客户端的执行顺序

+------------------- OutputFilter -------------------+
| +-------+      +-------+                 +-------+ |
| |filter1|----->|filter2|-----> ... ----->|filterN| |---------+
| +-------+      +-------+                 +-------+ |         v
+----------------------------------------------------+ +---------------+
                                                       | Hprose Server |
+-------------------- InputFilter -------------------+ +---------------+
| +-------+      +-------+                 +-------+ |         |
| |filter1|<-----|filter2|<----- ... <-----|filterN| |<--------+
| +-------+      +-------+                 +-------+ |
+----------------------------------------------------+

在服务器端的执行顺序

                  +-------------------- InputFilter -------------------+
                  | +-------+                 +-------+      +-------+ |
        +-------->| |filterN|-----> ... ----->|filter2|----->|filter1| |
        |         | +-------+                 +-------+      +-------+ |
+---------------+ +----------------------------------------------------+
| Hprose Client |                                                     
+---------------+ +------------------- OutputFilter -------------------+
        ^         | +-------+                 +-------+      +-------+ |
        +---------| |filterN|<----- ... <-----|filter2|<-----|filter1| |
                  | +-------+                 +-------+      +-------+ |
                  +----------------------------------------------------+
