Could you assign routing id within agent host implementation instead?

[yurys, 2011/08/16 08:14:48]

Done.

+
+ protected:
+  explicit DevToolsAgentHost(int routing_id) : routing_id_(routing_id) {}
+  virtual ~DevToolsAgentHost() {}
+
+ private:
+  int routing_id_;
+};

DISALLOW_COPY_AND_ASSIGN ?

The class is abstract, no need to put the declaration here.
