44 | | // Abstract interface for a callback. When calling an RPC, you must provide |
45 | | // a Closure to call when the procedure completes. See the Service interface |
46 | | // in service.h. |
47 | | // |
48 | | // To automatically construct a Closure which calls a particular function or |
49 | | // method with a particular set of parameters, use the NewCallback() function. |
50 | | // Example: |
51 | | // void FooDone(const FooResponse* response) { |
52 | | // ... |
53 | | // } |
54 | | // |
55 | | // void CallFoo() { |
56 | | // ... |
57 | | // // When done, call FooDone() and pass it a pointer to the response. |
58 | | // Closure* callback = NewCallback(&FooDone, response); |
59 | | // // Make the call. |
60 | | // service->Foo(controller, request, response, callback); |
61 | | // } |
62 | | // |
63 | | // Example that calls a method: |
64 | | // class Handler { |
65 | | // public: |
66 | | // ... |
67 | | // |
68 | | // void FooDone(const FooResponse* response) { |
69 | | // ... |
70 | | // } |
71 | | // |
72 | | // void CallFoo() { |
73 | | // ... |
74 | | // // When done, call FooDone() and pass it a pointer to the response. |
75 | | // Closure* callback = NewCallback(this, &Handler::FooDone, response); |
76 | | // // Make the call. |
77 | | // service->Foo(controller, request, response, callback); |
78 | | // } |
79 | | // }; |
80 | | // |
81 | | // Currently NewCallback() supports binding zero, one, or two arguments. |
82 | | // |
83 | | // Callbacks created with NewCallback() automatically delete themselves when |
84 | | // executed. They should be used when a callback is to be called exactly |
85 | | // once (usually the case with RPC callbacks). If a callback may be called |
86 | | // a different number of times (including zero), create it with |
87 | | // NewPermanentCallback() instead. You are then responsible for deleting the |
88 | | // callback (using the "delete" keyword as normal). |
89 | | // |
90 | | // Note that NewCallback() is a bit touchy regarding argument types. Generally, |
91 | | // the values you provide for the parameter bindings must exactly match the |
92 | | // types accepted by the callback function. For example: |
93 | | // void Foo(std::string s); |
94 | | // NewCallback(&Foo, "foo"); // WON'T WORK: const char* != string |
95 | | // NewCallback(&Foo, std::string("foo")); // WORKS |
96 | | // Also note that the arguments cannot be references: |
97 | | // void Foo(const std::string& s); |
98 | | // std::string my_str; |
99 | | // NewCallback(&Foo, my_str); // WON'T WORK: Can't use references. |
100 | | // However, correctly-typed pointers will work just fine. |
